She does make a good point. After everything he's lived through, including but not limited to alien invasions and Dalek attacks, he should have known better, and he should have never let a human get the better of him. But it's done now and next time, he won't have let his guard down. It's almost ludicrous that this whole thing happened to start with, and while he won't let on about it in front of her or anyone else for that matter, catching the Doctor off guard is just not a thing that happens.

So needless to say, he's not exactly pleased by anything that's occurred, and just by virtue of being in the clinic because of his own idiocy, his mood is not exactly pleasant either. It's not even that he wants someone with a good bedside manner. The lunacy of the whole situation is just beginning to eat at him and causing him to be a bit tetchy.

"Right, next time, I'll remember that. Always bring a tranquilizer gun." He shakes his head, knowing he'll be hard pressed to pick up any sort of weapon or threatening device at all. He'd rather be cut up again than have to shoot someone or otherwise hurt them. "Of course I know her. Fine sort of friend I'd be if I forgot about the person I've taken on traveling with me."
