There's a difference between being a grump and having a more mature outlook towards certain things, Doctor. We can't treat everything like one big joke...or I can't. Let's just say I've sort of seen what happens when you go around doing what you want with no thought of the consequences. It's fun, yeah. But there are always consequences, Doctor. No matter how harmless you think what you're doing is. [He sighs, not feeling bad for lecturing the other since he knows it'll just go in one ear and out the other with him anyways. His younger self was always too stubborn for his own good.]
I didn't attempt. I did it. Besides, I'd kick myself if I let that one go unanswered. You would too...probably.
[He lets the other go once they step inside, closing the door behind them and letting the Doctor roam as he wants. If touching doesn't hurt anything, then there's no harm in letting him explore a bit. Still, he can't help the smile that comes to his lips at the compliment.] Isn't she though? Still can't quite get over it, even now. [He slips past the other, settling at the controls, checking over the screen with a frown, expecting something more than just the normal readings from the TARDIS.] This can't be right...
