David grabs hold of the rope and begins to pull hard, using everything he's got. He hoists the young girl up. She is quite light and it doesn't take him more than a minute to lift her up and over the edge. He then quickly unties the seat and throws the rope back down. Kneeling so he's eye level with the girl he says "ok, I'm David...I need to help the people down their so I need you to stay right here next to me" he says "just hold onto my tool belt" he then turns and stands grabbing his gun and taking aim at the next zombie something in his head warning him to conserve ammo and not fire like a mad man.
