Julian and Ezra

Julian and Ezra are at the start very disliking of each other. Julian dislikes Ezra because he broke his vows as the Right Hand to Isiah Copper by killing him during Scott's Rebellion, and Ezra disliking Julian because he thinks that Ezra's blind loyalty to the Empire he serves is infuriating.

Eventually, Ezra and Julian are forced to pair up together on their quest to hunt down the Blacktydes and arrest them. They dislike each other heavily at first, disagreeing on methods of arresting them. As time goes on however, they slowly learn to trust each other and begin to work alongside each other on their quest to find the Blacktydes, with the inciting incident being when Julian and Ezra are chasing down Beatrice and unbeknownst to them, Ryker, Julian ends up tripping on one of the buildings and Ezra is given the choice of chasing down the two revolutionists and ending the revolution then and there, or saving Julian from falling to his death. Ezra chooses to save Julian and says he only did it because Ezra wants to be the one who kills Julian, not the pavement on the ground.

Later on when Scott is scolding Ezra for not catching the Revolutionists, Ezra lies and says that it was one of the peaceguards who fell on the building and not Julian, much to Julian's confusion. As they continue working to chase down the revolutionists, they still continue to disagree often, but rather than flat out arguing they try to understand each other's argument.

Eventually when Julian and Ezra are captured and Ezra believes that they're going to be killed, Ezra admits that he killed Isiah Copper in order to save all of Los Angeles from being burnt down. After this point, Julian stops calling Ezra the vowbreaker and adresses him by his first name.
