There were bows in the Inn, but Thorfinn had borrowed the axe a lot and felt like asking for something else would be pushing his luck. Even if he could likely sweet talk Kate into it, he'd rather not.

Hearing the door hit hard, he looks over to the door his eyes going wide, all the wrong instincts kicking in, but there was no time to react besides looking back. The second his mind connects who it is and the edge to her voice, Thorfinn KNOWS he has messed up. It was almost like being a child caught in his father's trunk again. But, only a fraction more worrying, because Jo isn't his father, Jo could leave if he made a wrong choice, upset her to much. He didn't want to even think about that prospect.

At Kol's words he looked back to him. "You wouldn't have. I would have stabbed you first." It's not bragging, just stated as the fact he felt it was. If he really felt he was in danger he would have, but only when that fight or flight instinct kicked in. A sad fact to how little he understands the supernatural. He thinks he could have stopped Kol.

Looking back to Jo he gave an apologetic look. "Sorry, should have closed the door." He saw nothing wrong with offering her as well, they were a team in his eyes. Three surviving in a strange world. Kol was part of the team.
