Carolyn Andrews. Eighteen and a part time nurse in the tunnels. She lost her little sister and her parents from radiation... she doesn't know why she's the only one who made it. It made her want to help anyone she can as much as she can. She's become very forgetful after she moved into the tunnels... and she keeps misplacing things. That's why she's only part time as a nurse, she has to memorize what she has to do.
