There's an almost immediate change in Sam's bearing as soon as Stacia says, "I'm a werewolf." The smile, the 'friendly giant' demeanour falls away and he straightens, managing to look fairly imposing even while sitting.

Internally, he was running down what he knew about werewolves and if there would be anything of use here. Unfortunately, he was already coming up empty. If this turned bad, he was in more than a bit of trouble. Even the fact that Stacia was fairly small and doing her best to look harmless didn't mean she was actually harmless. He'd been hunting far too long to just write her off for being five foot nothing.

After a moment, he nodded, expression still closed off as he worked through that. "All right. I'm not sure what that means for you in particular. I know what it would mean back home, and it wouldn't be good." The look in his eyes wasn't exactly wary. A little more interested, wanting information first before deciding to jump one way or the other. "That said, since I'm fairly certain by now that we're not from the same world, I'm going to hope that while that might mean you turn furry on the full moon, it doesn't mean that you do things like tear the hearts out of humans in order to feed."

It's said pretty mildly, but Sam's body language says he's ready to move in moments if necessary. So not QUITE as mild mannered as he had been trying to come off as.
