I don't want to be just one thing, I can't be. I want to be brave and I want to be selfless, intelligent and honest and kind.

–Tobias to Tris Prior, in Divergent

Tobias Eaton, more prominently known as Four because of his four fears, is one of the main characters in Divergent,'Insurgent, and Allegiant and is the son of Evelyn Johnson-Eaton and Marcus Eaton. Alongside Lauren (instructor of Dauntless-born initiates), he is the instructor of the transfer initiates. He becomes the love interest of Tris Prior later on in the first book of the trilogy. 


Early life

Tobias was born to Marcus and Evelyn Eaton in the Abnegation faction. His father was said to have noticed his Divergence at a young age and became observant of him since then. Evelyn supposedly died when Tobias was young, leaving Tobias alone with Marcus. Tobias became a victim to his father's cruelty. During his aptitude tests he got an Abnegation result, but chose Dauntless as his faction at the Choosing Ceremony to escape his father. During his initiation training, when he went through his fear landscape, it was discovered Tobias only had four fears, with the average being between ten and fifteen. As a result, his instructor, Amar, started calling him "Four." Tobias accepted it so he could escape his past. He finished first in his initiation class, and chose to work in the intelligence sector of Dauntless, but also decided to train transfer initiates.  


Four is first seen helping Tris get out of the net after she jumps through the hole into the Dauntless compound. After all the initiates have come in, he introduces himself as the instructor to the transfer initiates.

Four supervises their training, showing them how to fight with weapons, as well as hand-to-hand combat. Tris' fellow initiates, Christina and Will, both comment that Four seems like someone to stay away from. Four tries to help Tris out with her combat abilities, though Tris is wary to trust him, initially. During Tris' first fight, against Peter, when Tris starts being beaten badly, she notices Four leaving the room. When she comments to him about this, he says it "wasn't something I wanted to watch," confusing her.

Four is next seen when the initiates gather at the tracks to play a Dauntless game of capture the flag. On the train, Four and Dauntless leader Eric are the two captains under which initiates will be split up into two teams. Four surprises Tris, as well as the rest of the group, by choosing her as his first team member. Tris later notices that all the members Eric picked have bigger builds compared to Four's picks. Eventually, they come to the amusement park, and Four tells them to come up with a strategy before the other team picks their spot. While the other members start bickering about a strategy, Four notices Tris sneak off toward the ferris wheel.

He follows her, and she says she's "seeking higher ground" to find the other team. Four climbs with her, and Tris later realizes he has a fear of heights. They're able to climb high enough to find the other team's flag, but on the way down, Tris loses her footing and is dangling in midair. Four climbs down and turns on the wheel, helping Tris ride down and safely land. They come back to the group, and Tris devises a strategy to go into two groups, with half distracting the team while the other gets the flag. The strategy works, and Four's team wins. Though Christina is the one who captures the flag, Four tells Tris "well done," acknowledging her role in their win.

The next day, the initiates are shown how to throw knives by Four and Eric. After they start throwing, both Eric and Four notice that Tris' friend, Al, hasn't hit the target yet. Eric tells him to go get his knife when he misses again, but Al refuses because he's afraid of being hit by a stray knife thrown by the other initiates. Eric has them stop, and tells Al to stand in front of the target. Eric calls Four over, and tells Al to stand in front of the target while Four throws knives at him. If he flinches, he's out. Just as Four is getting ready to throw, Tris stops him and voluntarily takes Al's place. She manages to stay composed while Four throws the knives, believing he won't hit her. He throws a knife that nicks her ear, and she later calls him out for doing it on purpose. Four admits it, saying if he hadn't, Eric wouldn't have let her go. When she yells at him for "taunting" her, he angrily tells her that if he wanted to hurt her, he would've by now. He storms out before she can ask what he means.

Tris is paired up against Molly, Peter's sidekick, in her following fight. She manages to knock Molly off her feet, and proceeds to repeatedly kick her while she's down, leaving Molly bloody and bruised. Four finally has to pull Tris away, telling her to stop since she won. Tris notices that Four is looking at her with shock. He tries to get her to calm down by walking away, but Tris insists that she's fine. During Visiting Day, Tris introduces Four to her mom, Natalie Prior. Natalie comments that Four looks familiar to her, though Four dismisses it, saying he doesn't care to be associated with Abnegation. During the second stage of initiation, Four supervises the initiates as they go through their fear simulations while under a serum. Four figures out that Tris is Divergent, and though she denies it, he tells her to find a way to conceal it or she could end up at the bottom of the chasm. Tris wonders if he's Divergent, as well.

When rankings for stage two are posted, Tris finds herself ranked first. Soon after, she's attacked by Peter, Drew, and Al, when they try to throw her into the chasm. Four hears her screams and manages to stop them, severely injuring Drew while Peter and Al run away. Four brings Tris back to his room. Though he tells her to act scared so Peter and Drew won't attack her again, he is furious when Tris tells him they tried to assault her. He encourages her to humiliate them in some way.

Four shows the transfers the fear landscape room, where they'll try to conquer their fears as their final test. Tris later notices him going alone toward the room, and follows him. Four realizes she's following him, and reveals he wanted her to come so he could show her something. Tris goes through his fear landscape, and finds out his true identity. She protects him from Marcus when he shows up in his landscape, preventing him from hitting Tobias with a belt as he usually did. He's amazed afterwards by her actions, and credits her for helping him get through his fears. They later make their way next to the chasm, where Four shares with Tris his test results and how he chose not to be a leader because he didn't want to see his father again. They share their first kiss during this time.

The next day, the initiates go through Lauren's fear landscapes as preparation for the final. But when Tris goes in, facing Lauren's fear of being kidnapped, the fear morphs into her own, and Tris freaks out. Tobias shuts down the simulation, and yells at her for being "pathetic." Tris hits him, and tells him off before running away. She goes to Erudite to visit her brother, Caleb, before being driven back to Dauntless compounds after getting caught. Eric reprimands her for leaving, but Tobias comes out, and the two come up with a story that Tris has a crush on Tobias, and he rejected her, so she ran off, upset. Eric buys it, and Tobias talks to Tris alone, who scolds him for yelling at her. Tobias insists he was trying to protect her so no one would know their relationship and accuse him of choosing favorites; Tris understands, and they reconcile. 

Tobias has Tris meet him later that night, and the two of them get onto the train. He brings her to Erudite headquarters, where he shows her that their lights are on throughout the night even though it's against city rules. Tris makes the connection between the lights and the recent articles Erudite have written, slandering Abnegation city leaders. She also figures out what Tobias has: Erudite are planning to use Dauntless to overthrow Abnegation and take over the government. Tobias doesn't know how, and Tris admits she doesn't know, either.

On Initiation Day, Tris realizes Tobias is monitoring the initiates, but he can't see the simulations as Dauntless leaders can. After Tris goes through her test, Tobias brings her back to his room, where they start making out. Tris, though, pulls back and reveals to Tobias that he was in her fear landscape because she's afraid of being intimate with him, thinking he only wants her for her body. Tobias insists that's not what he thinks of her, and she says he's probably not going to be in her fear landscape anymore. At the dinner, Tris is ranked first, and she's accepted into Dauntless. Tobias comes up to congratulate her, and she kisses him, not caring what others think, but she pulls back, realizing how Erudite are going to use Dauntless, insisting she'll tell him later.

Tris' assumption is proven correct, as Erudite activate a tracker serum put in every Dauntless member, making them sleepwalking soldiers, that night. Tris sees Tobias next when she gets onto the train, and is afraid she was wrong about him being Divergent, as well. He grabs her hand, though, revealing his Divergence to her. The two get down with the other soldiers at Abnegation, where the leaders are rounded up to be killed. At one point, Eric decides to shoot Four to get rid of his competition, thinking no one will notice, but Tris stops him, shooting him in the foot. She and Four run, but don't make it far because Tris is shot, and Tobias refuses to leave her. The two are brought before Jeanine Matthews, leader of the Erudite, who decides to use Tobias to test out her new simulation serum for Divergents, and leaving Tris to die since she's wounded. Tobias tries to attack Jeanine to prevent this, but fails and is dragged off by her guards.

Tris is saved, and comes to Dauntless headquarters in order to shut down the simulation. She comes to the control room, where she finds Four under simulation monitoring the other Dauntless soldiers on the screen. The two of them start fighting against each other, until Tris manages to get Tobias' gun and points it at him. Not able to shoot him, she puts the gun in his hand and he points it at her head. However, her voice comes through to him, and he breaks out of the simulation. They shut down the Dauntless simulation, and run out, where Caleb and Marcus are waiting. Tris pushes Marcus away from Tobias when Marcus hugs him. She lets him know that she thinks Tobias has the right to shoot him, though she might do it herself. The four of them jump onto the train with Peter, who helped Tris get into the control room after she injured him, and they head towards Amity headquarters.


Tobias and Tris both enter the Amity compound, where the surviving Abnegation members and loyal Dauntless have gathered. However, soon after, the compound is attacked by the Erudite, and Tobias and Tris both run towards the trains, evading the Dauntless traitors sent by Erudite. On the train, they find Edward, one of Tris' fellow initiates who quit after getting his eye stabbed by Peter, inside, and they realize they have found the factionless. Tobias then tells them his name in order to stop them from attacking. Edward recognizes him, and brings him to the factionless leader - Evelyn, Tobias' mother. Tobias later reveals to Tris that his mother contacted him after he joined Dauntless, and when he met her, the reunion wasn't a happy one. Later that night, Tris overhears a conversation between Evelyn and Tobias, where she tries to convince him to get the Dauntless to ally with factionless. Tobias isn't sure he can make that happen since he's not someone held in high regard. Evelyn then says he should "become important."

Tris and Tobias leave to Candor headquarters to devise a plan. There, the two of them are subjected to the truth serum, and Tobias' abusive past is revealed, as well as his wish to leave Dauntless to become factionless until he met Tris. Afterwards, Tris reveals, while under the truth serum, that she killed Will while he was under simulation. Christina is heartbroken when she hears this, while Tobias is upset he never told her this before. Tris overhears a conversation between Marcus and Johanna Reyes, the Amity representative, about some important information that could change everything. When she tells Tobias, though, he discounts it, saying Marcus is lying to make himself more important. Tris thinks Tobias knows Marcus better, but she still has her doubts.

When Tris and other Dauntless members is ambushed by Dauntless traitors on the rooftop of Hancock Tower, she is captured by the traitors as a Divergent. However, just as she manages to stab Eric, who captured her, Tobias bursts in with other loyal Dauntless soldiers, and manages to save her. He later reprimands her for confronting the Erudite when she only had a pocket knife, and when she insists it was necessary, Tobias reveals that he doesn't want to lose her. Meanwhile, the Candor have started mocking and teasing Tobias about being abused by his father.

Tobias helps the other Dauntless soldiers by spying on Jack Kang, the Candor leader, and finds out Erudite is going to send a representative of Jeanine to discuss a negotiation. Tris figures that they need to listen in to the conversation to find out what Erudite is going to ask for. When Tobias is openly mocked in the Candor cafeteria, he gets up and heads for Marcus, also at the compound, and publicly beats him up in the cafeteria. Tris is shocked by this sudden outburst, but later realizes it wasn't sudden. Tobias claims he no longer wanted to be mocked by everyone, but she realizes he wanted to be held in high regard by Dauntless in order to assist Evelyn's plan for him to "become important." Tobias then asks her about spying on Jack Kang, arguing she's not able to carry a gun. Tris refuses to back down from spying, despite several others going, and Tobias tags along to protect her. During the stakeout, Dauntless member Lynn shoots Max, Jeanine's representative, and Tris leads a group to the place she believes Jeanine is hiding. Before she can get there, Lynn's sister Shauna is shot and injured. Tobias is furious with Tris for her actions, and warns her that if she continues to be reckless, he's done with her.

Dauntless members at Candor gather together to discuss Erudite's demands and their next move. They decide to create new leadership, and elect Tobias, Tori Wu, and Harrison as the new leaders. They also decide to put Eric on trial, since he's a Dauntless member, and their responsibility. During Eric's "trial," he asks Tris to state his crimes, and she realizes it's his way of getting to Tobias. Eventually, they sentence him to death, and he tells Tobias to execute him, hoping he will have to live with the guilt. Tobias doesn't feel guilty at all, and kills Eric. Afterwards, Tobias jumps onto the train with the other Dauntless members to head back to headquarters.

Tobias pulls Tris aside that evening to join him for a meeting. Tris notices that he went through his fear landscape again. They get on the train, and he reveals that one of his fears has changed; instead of having to kill a woman, he has to watch Tris die and cannot help her. Evelyn and Edward jump on the train, and Tobias says he wants to negotiate an alliance between the Dauntless and the factionless to take down Erudite. Evelyn accepts, but after she and Edward get off, Tris reveals that she doesn't trust Evelyn, and believes she has an ulterior motive. Tobias doesn't think she has a clear perspective, and chooses to discount her suspicions. Tris gets off the train, angry at Tobias' words.

That night, the Erudite activate a simulation serum, and send a message saying that the Divergent have to surrender or members will be killed every two days. Tris and Christina are able to save Kee and Hector, two members under simulation, but a third member, Marlene, jumps off the roof and dies. Tobias approaches Tris at dinner the next day, telling her not to make any decisions until they've talked about it. When Tobias finds Tris in his room later, he reveals that he knows she's lying and planning to go to Erudite. The two of them argue about the situation, with Tris saying this is the only solution. Tobias becomes angry, and admits to Tris he wants her to stay for him. Tris tries to convince him he'll go on, but he tells her to promise to stay for his sake. Tris agrees, but that night, she goes to Erudite and turns herself in.

Tobias later gets into the Erudite compound, supposedly trying to rescue Tris. Tris sees him while getting escorted by Peter, and he claims he turned himself in, as well. Tobias is later brought into a room where Jeanine has Tris strapped to a table, and Tobias reveals to Tris that Jeanine wants information on the factionless safe houses. In order to achieve this, Jeanine injects Tris with a concentrated fear simulation serum, making her completely overwhelmed by terror. Tobias tries to stop it, but when he can't get away from the soldiers holding him, he tells Jeanine where the safe houses are. Soon after, he manages to fight off both his and Tris' guards, and runs through the hallways. He then pulls her into a closet, where he reveals that he came here to get intel on Erudite headquarters, so that the Dauntless and factionless could break in two weeks from then, when Tris' execution was scheduled. Tobias tries to encourage Tris to hang on till then, though she feels she can't. The two are captured by the guards soon after.

Tris' execution is moved up when Jeanine becomes frustrated at not being able to find a serum to keep her under, and decides to execute her and run the experiments with Tobias instead. On the day of the execution, Tris walks by the room where Tobias is being held, and hears him screaming to let him "see her." Tris puts her hand on the window from the outside, and Tobias notices, and puts his hand alongside hers from the inside. Tris notices his face is red and splotchy before she leaves. Tris supposedly is executed, but is actually rescued by Peter, who brings her to Tobias. The three escape together, heading to Abnegation where the factionless and Dauntless have gathered. Peter says he felt like he owed Tris after she saved him from being shot at the Amity compound when Erudite raided the place.


Tris Prior

Looking at her is like waking up.

–Tobias on Tris, In Free Four

...she didn't want to leave you.

Caleb Prior on Tris, in Allegiant

Welcome to Dauntless
Four first meets Tris.

Tris is Tobias' girlfriend. He first meets Tris, when she is the first transfer initiate to jump off a building unknowingly into the net in the Dauntless entrance on the day of her Choosing Ceremony. Tobias starts developing feelings for her, since she was an Abnegation transfer just like him. Over time, he eventually reveals his feelings to Tris when he starts protecting her from other initiates and Dauntless leadership, as well as covering up evidence that exposes her as Divergent. Tris eventually reciprocates, and the two start dating. They work together to stop Erudite from usurping control of the city, fighting against Dauntless traitors and Erudite leadership to thwart their plans.

As much as the two can work together and be a strong team, they are each other's weakness, as well. Tris becomes protective of Tobias, as well, after finding out about the abuse he endured from his father, though she sees him as a strong person. When Eric is put on trial in front of Dauntless, he tries to get Tris to speak up in order to get at Tobias. Tris realizes how she can be used to push Tobias, and isn't happy about it.

Tris and Tobias are both intelligent, but also outspoken, which leads to them fighting quite often. The two of them become distant when Tris reveals she killed her friend, Will, under truth serum, and never told Tobias. He comes back for her, though, when she almost gets killed by Dauntless traitors. When Tris continuously puts herself in danger in Insurgent, trying to stop Erudite, Tobias becomes angry at her reckless actions, because he's become afraid of losing her. When Tobias enters his fear landscape again in Insurgent, he finds out one of his fears has changed into watching Tris die and not being able to help her.

Evelyn Johnson-Eaton

In Insurgent, it is revealed that Evelyn is Tobias' mother, who was supposed to be dead, is in fact alive and leading the Factionless. She faked her death, putting up a fake story about her dying during childbirth. Tobias was not happy to see her because she willingly left him with Marcus. Later in Insurgent it is revealed that Evelyn left because her other choice was exile because she had an affair with another man. Tobias' feelings toward her soften when he learns this and he starts to believe her, but Tris thinks she was a liar and is using Tobias, and threatens to tell him so.

Marcus Eaton

Tobias has an very strained relationship with his father Marcus, the leader of Abnegation, due to the physical beatings he endured

. Physical and emotional torment continued throughout Tobias' childhood, with Marcus repeatedly saying, "this is for your own good" every beating. The result was that Tobias left Abnegation due to his abuse from his father, as revealed in Divergent.

Tobias declined becoming a Dauntless leader because it would mean he would see his father more frequently. Tobias' relief is evident, whilst Marcus' rage hit a new high after his son left Abnegation, tarnishing his already blemished reputation.

In Insurgent, Tobias humiliates Marcus in the Candor meeting room. Tobias publicly beats and whips Marcus in front the crowd of Dauntless, Amity, Abnegation, Candor and Erudite, after receiving taunting comments. Often, Tobias was called a "coward" after his revelation of being beaten by Marcus during the Candor Truth Serum questioning with Tris.

Tobias later explains to Tris why he publicly beat Marcus, stating that he was sick of being jeered at by his fellow faction members, but most likely the truth is he wanted to be leader, which he becomes later in Insurgent.


  • Four's fears are heights, confinement (claustrophobia), killing innocent people (symbolized in his fear landscape as having to shoot a woman) and being beaten up by Marcus (his father). However, as said in Insurgent, his fears switched over the course of the trilogy. In Allegiant, it is revealed that the heights and confinement fear remain the same; instead of having to kill a woman, he must watch Tris die, and it is shown that instead of being beaten up by Marcus, he is afraid of turning into his father.
Theo James
Theo James will play Four
  • When Tris tells Tobias that he may not be in her fear landscape anymore, he says that everybody could call her Six, referring to her then only having six fears, to which Tris replies, "Four and Six".
  • In the movie, Four's age has been changed to 24, instead of him being 18.

Film Portrayal

Summit Entertainment bought the rights to create a film adaptation of the novel. Theo James has been cast as Tobias "Four" Eaton. The film will depict Tobias Eaton as an older instructor by the age of 24 instead of the original 18 in the novels.
