Even if Lydia had already told Allison about Derek being here, there's still some surprise when she sees him walking up to her. Partly because she didn't expect it but, then again, it's not like things had ended badly between them. Allison couldn't say that she trusted Derek, but Scott had. Isaac and her father had, too. And Allison trusted them, so by default she had ended up trusting Derek at least in some way as well.

Now... Here they are. Whatever her feelings towards Derek Hale could have been in the past, it's at least someone from home, and she returns a similar smile to the one that Derek has on his face.

"Hey. Thanks." She gives a small nod, as if to say that she means it. And, she understands what he means, about the whole finding each other in this place. "Yeah, I'm okay. How...are you? Have you gotten used to this place yet?"

At the last part, she keeps her voice low as she casually inches a little closer to him, as if to keep that part between them and it won't be taken as treason by someone in the crowd just for asking that question.
