Too late, by the time the Doctor was finished sorting through things and preparing, he thought he was in the clear until he slipped and nearly drowned in the stuff. Which wasn't possible since it wasn't even 1 inch thick on the ground, but still, enough to smear his entire backside and hair.

He'd have to settle with finding something later, or if he was really inclined, could make a trip back to the TARDIS, but time wasn't on his side at the moment. He almost felt like he literally could hear it ticking in the back of his mind.

Waiting back in the alley where they had arrived, he waited her her return, anxiously tapping his foot. They needed to get back underground and arrange things there.
