[ Youths. The Doctor likes children (normally)(it depends) but the ones who reach the age where they default to snotty? No thank you, no way, not at all. The fact that this child's attire looks like straight out of something Hans Christian Anderson only makes him a little bit annoyed. He's already been wrong about Robin Hood, he really doesn't also want to be wrong about...Hansel and Gretel or something like that. ]

I'm more fit than you realize, Mowgli. [ he knows this kid isn't Mowgli. but if he calls him by the wrong name, maybe he'll end up telling him his actual name. Maybe. ] This body's built like a tank, I won't be taken out just by falling over or jostling something funny.
