Why can't the show make it's mind up about what's supposed to have happened to Galifrey? From the episode it seems as though we're supposed to think that The Doctor always thought he destroyed it & the Daleks when actually he just forgot he'd captured it in a time lock, due to the presence of multiple Doctors, but it was already established that he knew he'd captured it in a time lock, hence The Last of the Time Lords when Galifrey came back. Even when the Docs went to Galifrey to help War Doc blow it up, 10 exclaims "this place should be time locked" BEFORE THEY HAVE THE IDEA TO TIME LOCK IT!! It would be nice if someone less confused would explain.
