Rachel just nodded, her eyes dropping a little at the explanation of how he knew.  She wasn't surprised, but it only exacerbated something that she didn't like: the way that her nature forced her not to be able to blend in.  Stealth and discretion were second nature to doppelgangers, and issues with the school combined with how much trouble a single doppelganger could get into very quickly made the rule rather necessary.  However, it didn't mean that she liked it, and it didn't make her any happier to be here.<br/><br/>Lost in her own thoughts, she didn't even notice someone trying to trip her until Marcus had already saved her.  Although she appreciated his aid, she didn't like how much attention she was already drawing.  The name tag was bad enough, and people who didn't understand would usually laugh and point and leave it at the end of it.  Since they never actually wanted to be her friend, they didn't look at her close enough to notice how different she was.  At worst, a few had simply guessed that there was more than one Rachel Kyleson, or that it was some sort of political statement akin to claiming to be Spartacus or other figures.<br/><br/>It just wasn't something she wanted to deal with right now, and Mark's frightening of the other girl didn't help matters any.  "Maybe I should just go change," she said softly, glancing around at the various classroom doors to consider which area would be quiet and secluded enough, along with using a phrase innocuous enough to imply another kind of change.  She had no idea what she should change into in order to be less picked on or draw less attention, but she'd think of something.
