She's Making Progress!.

Eve can't stay, so she tried leaving but stopped on hearing Quinn say. "Take one more step forward again and I call our close relationship off and also make life at school hell for you" Quinn threatened, staring at her mom straight in the eyes. If her mom loves playing games and wants to play this game, then she should have known Quinn's a master at all games.

Principal Young scoffed, watching how her daughter is acting so disrespectful to her and disgracing her in front of her friend. Thinking she's actually smart and tough by doing this. 

The tension in the room became too much for Eve to take in. She doesn't want to go against Principal Young and at the same time Quinn too. But it would be much disrespectful for her to listen to Quinn and not her mom. She's also rude and stubborn, but Quinn's own is just extraordinary.
