Due to past issues, I would appreciate if you asked before posting this anywhere.
How awkward would this be if it were to happen. I'd imagine it would end with the Doctor sitting at Sugar Cube Corner and sobbing over a piece of pie whilst loudly claiming, "my own wife almost didn't recognize me!"
She didn't recognize you because of the fez, man. Even though he's not wearing one here.
As a heads-up, I probably don't share your headcanons on Doctor Whooves so what you get from this may vary. Funnily enough, my own headcanons contradict this comic entirely.
