Well, that was an emotional way to conclude Christmas.
On Doctor Who Season 7 Episode 16, Matt Smith bid farewell to his beloved title role by regenerating into Peter Capaldi during the installment's moving final few moments.
He saw Amelia - the first face his face ever saw - once again. He said goodbye to Clara. And he came face-to-face with a returning Amy Pond for a couple seconds.
It was tear-inducing stuff... and then - whoosh! - like that, it was over. Capaldi's version of The Time Lord debuted, yabbering about his kidneys and asking Clara one basic question: Can she fly the TARDIS?
