Stefan and Neo
Stefan didn't wear "I'm a vampire" on a t-shirt on his chest, so there was really no way that she would have known. It wasn't as if she was in any danger sitting next to him. Stefan wasn't that kind of vamp, anyway. He was the protector kind, not the dangerous kind. --well, most of the time.
When she lifted her phone and typed into it, Stefan was a little curious. He cocked his head to the side, then read what she'd typed. Maybe she had some kind of a speech problem? He was open-minded.
"I hope it's not too frightening," he commented softly. Not that he would be scared, really... it just seemed like the right kind of thing to say. "Do you like scary movies?"
