This is just the Doctor being shocked by her own quirks and not quite sure who the feck she is. She should be into that by now. She still looks shellshocked whenever anyone calls her Doctor.

He went from a super serious, angry, "no hugging" Doctor, to a kind rockstar grandad. The transformation made sense too.
