What an annoying sound Quinn thought too himself, but it was a good sign in his mind, zombies don't breath he thought, he draws his machete though to be safe and taps on the door "Um? Hello? Anyone in there?" he looks behind him real fast to make sure nothing was coming up behind him and then said "I am a friend, really i am, I just want to get out of the open for a bit. Won't you unlock the door please?"
