The Doctor barked out a laugh. "Right, haven't got any plans to follow a fixed Time Agent." He paused. "That almost sounds vaguely inappropriate. Anyway! I can handle this on my own, I just thought having you on my side might make it a little faster."

Now it was the Doctor being both childish and stubborn. Not that he minded too much. He was a genius, after all. And perfectly capable of taking care of himself, even in a situation like this.

He was...better off on his own, really. Mistakes would always be made, but he was the only one who could get hurt in this case.
