In season two, Brady continues to be an entitled jerk who wreaks havoc on other people's lives. We see a flashback of him and Tabitha having Thanksgiving dinner with his pretentious, mildly racist family that makes his home life pretty unpleasant. But that serves as more of backstory for both him and Tabitha rather than an excuse for his behaviour. In the present day, Brady falsely admits to sinking his own car — which we all know Tabitha, Moe, and Elodie did in season one — just to get special treatment from his teachers who think he's a troubled teen.
Brady also constantly tries to get Tabitha back — even though he's now dating her ex-friend Kayla — but refuses to take any responsibility for his misdeeds. Instead, he blames Moe for his fallout with Tabitha, which is likely his motive for coercing her into swiping the midterm answers. His ploy causes him and Noah to fight, and he finally reckons with his actions when the school sees the exhibit that reveals his physical and emotional abuse toward Tabitha.
