Remember that Moffat demanded that series seven consist of 13 epic, widescreen episodes with “slutty” titles that suck audiences in. Well, it appears he saved the best for last! The Doctor’s true name has been a mystery since the very very beginning of the series, when Ian called him “Dr. Foreman” and the Time Lord replied testily, “Who? Doctor Who?”
The novel Lungbarrow suggests the Doctor’s name is d^3∑x^2.
The real mystery here is, Will we get the Doctor’s true name? Rule No. 1: The Doctor lies. Rule 1a: Moffat lies. So what’s a fan to do?
We have to trust the Grand Moff, who has not let us down yet this season. Maybe not every episode has been absolutely as epic as possible (I’m looking at you, “A Town Called Mercy”), but this season has been pretty damn wonderful.
And it ain’t over yet. Not by a longshot.
