Rick nodded. He thought he remembered Scott saying something similar before, but he'd chalked it up to his being young, athletic, and maybe a little bit cocky. He was about to ask what sort of advantage Scott thought he had over anyone else when Stiles spoke up. His statement made Rick pause, but--all things considered--it wasn't the strangest thing he'd heard. Or seen.
"Okay." He didn't ask how knowing about werewolves would give them an advantage over zombies. It seemed strongly implied that at least one of them was a werewolf. It also seemed a little stupid not to take him at his word when there were hordes of the walking dead outside. So he did his best to push past whatever skepticism he may have, and ask the relevant questions. "What do I need to know?"
