Even if they were in the heat of their argument, there was no way in hell sh was going to let Dean go after Sam alone. She did see Sam as her own younger brother and if it was vampires that had taken him then she knew Dean would need help. She couldn't help but also wonder why the hell John wasn't out here trying to find his son, but here they were doing the one job John bloody Winchester should be doing. She was thankful that Dean let her catch up to him as she then caught up and proceeded to keep pace with him as they crossed the road and to the entrance of the woods. 

As they entered the woods and came to the premade trail, she really hoped they were both wrong in thinking this girl Sam followed was a vampire. The idea of them being possibly so close to the main town was unlikely to her but she also knew hunts could lead them to many surprises and maybe this was one of those moments. She looked at Dean as he pointed out the pre made trail, "I really hope it's not vampires and it's just some random kid he's run off with. But let's keep our heads level either way. We do this together to bring him back" she replied to him.

Sam smiled when his awful joke made her at least chuckle. He knew he wasn't great at making jokes but he didn't care. He let her pull him into the cabin as he looked around at how it was holding up, making notes of how the floors creaked and really hoped that them doing this won't attract any of the vampires that they were even in town for. He smirked at her words, "It'll do" he said back to her before he suddenly got taken off guard and almost off balance when she just flung herself onto him and kissed him. He didn't fully know what to do or how to react until he suddenly felt his brain kick back into gear and kissed her back.
