For some reason I can just see a Big Daddy at first charging around looking for what made her bleed. Then when he finds out there isn't a splicer (or no longer one) anywhere nearby he starts panicking at why she's bleeding.
Shes a infected(kind of live splicers but with a virus instead of ADEM and the mutations don't let you shoot fire but they do alter the body and mind a greater deal) that cries all the time unless provoked then she will run screaming at you and attack you with her two foot long claws(which are one hit KO)and then run away crying with her hands covering her face.
Well, not literally screeching like the big sisters do, but constantyly nagging you to death in her british accent sayingthe same things over and over again, like, "Eleanor is not your Daughter Delta." or "you were made for the rapture family"
