I think unfortunately I tend to identify with Cuddy more than is good for my writing, and I'm pretty hot-blooded. But I think she's possessive enough that thinking of what Wilson had done (and she had, after all, refused to do, and had imagined House to have given up for her sake LOL) made her go really berserk.
She might not have been SO violent hadn't she been drunk, though.
I can't wait until the next work day :-).

I also think House really wouldn't view this as infidelity. It's Cuddy's failure to be GGG that is to blame.
