All Derek's fault! "Jack?" Lawrence said. Jack wasn't paying attention, so Lawrence poked him in the ribs.
"Hmm?" Jack still didn't look away from the well. "I think I've just seen an old friend."
Lawrence sat up and looked around. The horizon was bare but he said, "What tribe?"
"No tribe you know," Jack said and, as he spoke, a tentacle flopped out of the well. Jack grinned. "Great. Lawrence, I'd like you to meet Cthulhu. He's a... very intimate old friend of mine."
