The police are still outside, but they won't bother to search this building, especially not a few stories up. But, well, it would take them some time. Which meant he and this girl had to keep themselves tucked away for a small amount of time. Enough, he felt, to try to help her.

"Here," he said, holding out his hand for the knife. Since it was already out, he wouldn't bother fetching his. No need to startle her more. "Let me."

Which probably sounded odd.

"I've seen similar traps before. Set them, too. I can get it off easier."

...Which didn't help him. But, well, it was true. He had more than his fair share of hunting experience. Because he did as he was told. If he was told to bring in a witch, he brought them in. If he was told to kill a werewolf, he killed them. He followed his orders, and he was good at it.
