Tris Prior

This section is in need of major improvement. Please help improve this article by editing it. In Divergent, Four first meets Tris, formerly known as Beatrice, 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. It becomes evident very quickly that Four has some sort of feelings for Tris when he walks out of the training room when Tris is unfairly paired up to fight with fellow initiate Peter who is much stronger than her. In addition, on the night of the capture the flag game, Four accompanies Tris as she climbs up the ferris wheel so he can be sure that she is not hurt even though one of his only fears is heights. Four continually tries to help Tris through her Dauntless training, and she begins to develop feelings for him as they interact with each other. Eventually they become a couple, and Four is adamant that he will protect Tris no matter what the cost is to him.


  • Theo James has been cast as Tobias "Four" Eaton in the film adaptations. The film will depict Tobias Eaton as an older instructor by the age of 24 instead of the original 18 in the novels.
