ending question (spoiler)

yep

Ramones, the best band ever.

There's only one "werewolf". The ending attacker was dear ol' dad defending his daughters honor, she having all that sexual intercourse and stuff. Remember he wasn't killed. Last we seen him, he was knocked out by a seditive dart and throw into the back of the pick up truck.

Look carefully at the attacker. No long muzzel full of sharp teeth and the left hand had fingers on it, not claws.

Gotta admire his persistence.

I like waking up in the morning not knowing who I'll meet or where I'll end up: The Titanic
