"No idea," the Doctor said, catching his coat. "Figured your tech search on that wriststrap of yours might help a bit."

He shrugged the coat over his shoulders, trying not to take too much notice of the blood along the inside from where it covered Jack's regrowing legs. Nothing a trip to the laundry couldn't fix, and Jack's coat would need one, too.

"Careful," he warned, leaning down to pull his modified TARDIS key from where it lay on the ground just outside of the door. "This cave is about to get fairly busy."

He lifted the key and the large insects from the outside crawled along the ceilings and walls, reclaiming the home the Doctor had shooed them from.

"Most of them are harmless, I think," he said.
