Flying a makeshift ship after being shot by a Dalek came to mind. And anyway, the Doctor was more interested in the fact that the Drudges had stopped for a moment. He'd really rather not damage the House if he could avoid it, but that's not very likely with the Master around, so he flicked the settings on the sonic, amplifying the signal that he'd been using before and tried another blast at the Drudges.

"Well, you know," he said, pain creeping into the edges of his voice but his tone still light and upbeat despite the situation. "There's always the chance of trying something new."
