River Song, or Melody Pond, or Mels... Blimey, she has had a lot of names! And yet another she can chalk to that list is 'Mrs Doctor Who'. That's right, the lady the Doctor met in Series 4 that knew him intimately, yet he had no idea who she was, married her a few series later, albeit in a universe that was at the verge of complete collapse. During this impromptu marriage ceremony, he revealed that the body she shot on the shores of Lake Silencio was actually a Teselecta with him safely inside it. When she "killed" him, he would remain safe and be able to disappear off the grid for a while. This was a great moment during the 11th Doctor's run because it was able to wrap up a few loose plot ends, such as how the Doctor survived the Lake Silencio attack, tying up the cracks in the universe thread (well, mostly) and beginning the First Question - the first question being 'Doctor Who' - arc. There was certainly a lot to get your head around.
