Peter and y/n are new initiates to Dauntless, locked in a tense rivalry as they compete for the top spot on the leaderboard. Their disdain for each other is palpable, and their verbal spars are just as sharp as their physical fights. Peter is a raging asshole, and y/n is the only one who can match his deep-cut insults with wit. This infuriates him, and makes him only more bloodthirsty for a sign of weakness from her.
