1. I guessed at the time that diner-Clara was a series 7 splinter (although in retrospect I don't think Moffat would have used a plot point that hadn't been mentioned for 2½ years).
2. There's a fantastic fan theory that the 'destroy a billion hearts to heal his own' are all the Doctors who die in the confession dial!
I do think “she’s a splinter who doesn’t know him, and he’s treading softly cos he can’t tell her who he is” is one of the things we are meant to assume is happening on first watch.
