Did you catch that he considered having a long scarf and rejected it as "silly?"

I assume that his face looked familiar because the Doctor has seen it twice - Capaldi was in the episode about Pompeii, as well as playing a recurrent character in Torchwood (John Frobisher, a definite slimeball). Maybe it was a tease, and we'll never hear it mentioned again. I don't think I knew before that he has a choice about his regeneration face/body. Is that new, or have I been oblivious for decades? I'd hate to think that it's the Doctor's choice to always be a white guy.
