She shrank back when he looked back at her and confirmed that he was in fact the notorious werewolf by the name of Fenrir Greyback. She wanted to run, but he knew she would never be able to get far enough to escape, and the fact that no one ever found where he kept his pack made her very weary that she'd ever get rescued. The only thing she could hope for was that she would, even if the chances were getting slim.
When she saw him get territorial over her, she watched as the other man back down. Though, she wasn't sure if he really was backing down. He was still looking at her like he wanted something she definitely wasn't willing to give, so she went willingly when he pulled her into what looked like a cave. She did notice that he was a little gentler with her than he had been, but she was still very afraid of what would happen to her.
As soon as he let her go, she scrambled over to the back wall and sat with her knees at her chest, and was thinking so hard on what would happen to her now that she almost missed what he said. "What? Oh. Um. I don't know." Her voice shaking the whole time, making it clear she didn't think they'd find her any more.
