I'd be seriously shocked if Vinny isn't responsible for trashing the DIKs mansion. Ep6 went overdrive introducing him to us (although he was already mentioned way back at the first Pink Rose visit). The stilted speech every time Nick mentions how Vinny left, and then the whole sneaky Nick bullshit when the laptop went missing, and then the surprisingly lack of damage done to Nick's room compared to everyone else. Nick even went as far as to ask the MC not to tell everyone about how he was "lucky" that his room wasn't so seriously trashed. We know Nick didn't trash the mansion since he was with the DIKs the whole time, and the Alphas would have to be utter meatheads to tag the building with their symbols - it was a total frame attempt.
Burke is so slimy, there's no way he's innocent. We know Mona didn't have a legitimate scholarship otherwise she wouldn't have even bothered prostituting herself out for the HOTs, she'd have no need for a HOTs sponsored tuition. So the Mona scholarship Burke was deleting was definitely bogus, and convincingly related to Quinn's prostitution ring. He's guilty as sin.
I hope Maya's dad is the first thing to be dealt with in Ep7. Getting sick of that fucker.
I agree Quinn is dangerous, in that shit may happen to her which will overflow onto others, but other than being a drug dealing, prostitute pimping, cunt of a woman, she's actually pretty nice.
