[It's probably for the best that the Doctor didn't see Narvin's moment of grace. He's far too busy trying to keep the TARDIS steady and try to land her in a safe place to let the humans out.]

Oi, no one asked you for advice! The temporal drift is supposed to be off; makes for a smoother landing! And--hey! [It's by then that he realises that the noises the TARDIS is making is not because of him, but from Narvin's own attempt at piloting the old girl. She's having none of it, and neither is he. He immediately comes around and swats Narvin's hand away before it can touch the Helmic Regulator.] I know how to drive her just fine. Took the exam enough times! [Never passed but hey, details.]
