Okay that's not AS BAD as Bertuzzi, but that's also not saying a whole lot.
Thornton (IIRC) had challenged Orpik to a fight earlier in the game and Orpik wouldn't go. The Code says that's done. It's over with. All Thornton can do at that point is to make sure he finishes EVERY check on the guy (which I absolutely would) and maybe a face-wash or something a little extra here and there but no matter how pissed you are at Orpik, you can't jump him. Makes Thornton no better than a punk.
