There was indeed something very off about Ruby, but she didn't seem to care about spending some time drinking with her new human friend. He seemed okay, and it wasn't like she had anything better to do or any kind of a life here, so a few drinks with some guy would not hurt. Bobby had said she should find something to do here, so now she was kind of taking his advice. It wasn't all that important that Slevin was human, it was unlikely he knew she was a demon anyhow.
She laughed at his toast, and downed her own shot. He had no idea how funny that really was.
