Jack had managed to grab hands as the hole in the floor opened up, and Jack made very, very sure he was holding tightly to the hands on either side of him. As he started to fall he managed to snap out, "Don't let go. Everyone through and down!" It was loud, it was fast, it was shouted out while he fell. It was going to hurt like fuck, landing that far down, yeah, but he was absolutely determined to keep them as close together as he could, and hey. He'd be on the bottom, which should soften the fall for the rest.
