A few of the survivors, Gerry, Lisa, Jack, and Mary are walking in an open field at dusk when they suddenly hear screaming from somewhere in the distance.

(Gerry) "What the hell is that?"

(Lisa) "I don't know, but I think we should get out of here."

(Mary) "Wait! There's another survivor over here!"

Mary points at you.

(Gerry) "Hold on. How do we know if they're not a woodcrawler?"
