Well Claire has long red hair and the one here has short brown/ black hair so we don't think it's her, it's not Angela either as again the hair is different and she's not in uniform. The only known characters it could be are Ada and Jill but both of those wouldn't really be scared and ducking from Zombies so i'm guessing its a random person Leon's just happenes to save.
what a guy!
Hope your enjoying your time with us Crazy4wesker
