Bigby's not sure at all what the fuck he's doing here. Sure, there's food and beer, but that's never been much of a motivator for him; he can get his own food if needs be, and he's not nearly as fond of booze as he is of his smokes. Wolves might be pack animals by nature, but Bigby's never had one. Mostly, he was here because he was curious.

Food didn't suck, though, so there was that.

It was a party, but still, Bigby kept to himself. He ate, he drank, he spoke when spoken to. And, most importantly, he observed.
