Howling:Get Out

When Amy and Canton visited the children's home, all the walls, and Dr. Renfrew's arm, had the words "get out" written on them. Does anybody have any idea who wrote this. Was it Renfrew warning himself about the Silence, similar to the Doctor and friends' tally marks, was it the Silence trying to scare people, was it the little girl trying to warn others about the Silence, or was it something else?Icecreamdif 03:24, May 6, 2011 (UTC)
