Alllll of this. As someone who plays a "normal" character, this post just says it all. Also, think about how seeing all these "special" people would affect your character, depending on their personality. I've seen reactions to being alarmed to feelings of inadequacy. Maybe she can try to learn skills to try and help when she can. Or maybe she can bond with other normal characters over their...normalcy.

A character shouldn't be defined by their powers or abilities. As long as the character has an interesting personality and is played in an interesting way, it'll be fine!
