I think you mean this statement?Well, I didn't know Vic had such violent tendencies. That's horrific. And apparently it wasn't a big secret either.
"Vic's violent rages that literally put a manager in the hospital..."
Unfortunately, it was never elaborated upon, so all we have is that (it's not good but it's a shame it's not elaborated upon). (edit: I wasn't able to find it at least in the thread, perhaps I missed it).
