Claire really couldn't know what Simon was dealing with unless he told her, and that was pretty unlikely since they had just met and all. If he wanted to tell her, he could. She was a pretty good listener, and she honestly would be comforted to find someone as messed up as she was, even if it was a little selfish.
She was willing to bet that he thought she was a good girl, maybe even sweet. She seriously doubted that he suspected she sometimes spent the night with a serial killer. This getting coffee thing was normal, and that was what Claire liked so much about it. She felt like she could just hang out.
"Happens all the time." Claire said. "New people arrive daily, and they always replace someone. Sometimes it is famous people, sometimes just regular ones." She shrugged. "It's a pretty strange place." When he said it was something that only happened in the comic books, she sort of looked down. He would probably think she was a pretty big freak in that case, if he ever found out her big secret.
