Sam gives the door a quick try-- locked, of course. He pounds a fist against the door once, in frustration, and faces the vigilante. "Kill it? D'you even know what it-- what that thing's capable of?" Because he sure as hell doesn't. Right now, the shrieking woman's a completely unknown variable. Maybe she really is a monster, or maybe she could be... sick, for all he knows. The thought turns his stomach.

Of course, Sam might feel a lot less conflicted once he realizes just how much of a danger the creature poses to innocent people.
