Moffat, who has spent the last year saying that multiple Doctors will not appear in the 50th episode, proves once again that he, like The Doctor, lies. Or at least manipulates the truth, this wasn't the 50th anniversary, but featured every (or at least most of them - I didn't see Paul McGann or David Tennant, but am prepared to believe I missed them) previous Doctor. He claimed there would be no two-parters this series, but this was totally the first half of the fiftieth anniversary episode. In an age where every spoiler is revealed months in advance this was a huge coup!
