Now, see, the Doctor has a rather sketchy opinion of cats, but until now, he's always had a relatively positive opinion of birds. But thanks to this misadventure, birds have officially descended to the same rung as cats.

"Right, and as for me, I'm just making a mental note to never, ever own a bird. Not that I was planning on that, but now this has just confirmed for me that birds are very irritating creatures."

Once the cover's sealed up, and they're relatively safe from the flock of birds, the Doctor finally glances over at Blake. "Your guess is as good as mine, but I'd say we should at least wait half an hour before having a look. You don't happen to have a watch on you, do you?"
