I think Vinny definitely trashed the DIK Mansion.
And again, I just don't see it.
The only thing this theory has is motivation with Vinny possibly holding a grudge against the DIKs, but we have obvious suspects in the Jocks who not only had the motive to do this but also the means and the access as well. We saw the dildos strewn and displayed all over the DIK mansion, the same ones the Jocks used before that the DIKs then used against them, so I think we can say safely that they were definitely responsible for the damage to the mansion's windows. We also know that they knew the mansion was unoccupied, so why wouldn't they do more? Yes, they're technically supposed to keep their heads down after the Chad incident, but they're the Jocks; a bunch of roided-up idiots who are probably too stupid and too macho to care. Also, remember that Dawe is going around handing out flyers of Cathy's pic taken from Rooster, so he's clearly not caring about repurcussions even though he was told the Jocks would be more closely monitored.
Vinny being responsible is more convoluted because either he was hiding in the bushes waiting for the Hell Week party to begin so he could crash it, or was told by someone that the mansion was empty, made his way over from wherever he was, got there in time to see the Jocks throwing dildos through the windows, and then proceeded to break in and to trash it all by himself, spraying Alpha symbols on the walls to put the blame on the Jocks. It's quite honestly daft to believe he did it when the suspects are much more obvious and clear cut than that.
Sorry to break this to you, but that means nothing. In fact Quinn was in the banner with other LI's BEFORE Jill even existed all the way back to during the planning stage of v0.1. That still didn't make her an LI.
Let's also remember this from Ep 6:
DPC's probably not-so-subtly telling people to not expect much from this.
I wonder if there's any drama between Tommy and Vinny regarding Quinn.
My guess would be they (Quinn and Vinny) had a relationship, maybe Quinn had actual feelings for Vinny, but either he didn't reciprocate or after he got expelled things just broke down between them and she's bitter about it. So perhaps she sees the MC as someone who reminds her of Vinny in certain ways but better than him, and it's why she doesn't want to get too close because she doesn't want to get hurt again and feels she doesn't want to have those kinds of feelings again.
Also, I think that this drug operation Quinn is running is the same one Vinny was running and he passed it to her when he was expelled. Perhaps Vinny
and Quinn were doing it together and Vinny got caught dealing but he didn't give up Quinn and she's still carrying on what they started together.
With regards to Tommy, I think he was interested in Quinn and her potentially being with Vinny may have been a source of contention between them. He probably gave up on trying to get with Quinn because she didn't have any interest in him in that way and so never gave him any opportunity to pursue something.
