Okay this is bugging me. Capaldi in the Pompeii episode is NOT the Doctor, he’s just a dad trying to protect his family during a disaster. We don’t know what 11 will be like when he regenerates but we know that the life 9 led and Rose had an effect on how 10 was, and 10’s tragic losses resulted in 11, a Doctor who needed to be young and a little childish. I think this time the Doctor will realize it’s time to grow up (again), act like an adult, maybe a father. What if when 11 is regenerating part of him remembers this man, this father, he doesn’t force the change, it’s subconscious really. He knows deep down he needs a face that reflects the man he has to be now and in the back of his mind he remembers the face of that father in Pompeii.
