Sonic screwdriver to the heart: Something old

Matt Smith might have been the youngest actor to ever play the Doctor, but he sounds so old here, at the end of all things. So weary, so tired, after rebooting the universe and putting all things right, and it's time for the Doctor to go too.

It's not the end of course, with the Doctor laying down a simple coded message that will bring him back to existence at the wedding of the girl who waited, and he'll appear in his box that is something old, something new, something borrowed, something blue.

But for a moment there, he really is leaving us all, and that earlier blaze of glory is quietly overshadowed by somebody who is moving on for good, and taking his endless kindness with him.
