WOW! What a hell of a series so far. Sooooo much things have happened, we've finally found out who River Song is Amy and Rory's daughter, Melody Pond. Not sure if she is The Doctor's wife yet, but I'm sure it'll all be revealed in September when the series returns. We've witnessed The Doctor regenerate and die, then a younger version of the same Doctor comes back.
Turns out that the Amy we've seen wasn't the real Amy. She was a ganger. The real Amy was pregnant and she did give birth. Some we girl in an astronaut suit killed our Doctor and then she just regenerated at the end of episode 1, but we'll find out what that was. It's now suggested that she may actually be a younger version of River Song.
We've had more than just the above, there's been Pirates, Nazi's, basically a female Popeye, the 10th Doctor's TARDIS desktop, a bearded 11th Doctor, scary as hell aliens (The Silence) and The Doctor's wife......his TARDIS!
Next half of "Series 6" (airing sometime in September) should hopefully be as incredible as this half has been. We see the return of James Corden, David Walliams as an ugly looking alien, more River Song aka Melody Pond, we find out more about The Silence, Amy and Rory's baby, female Popeye and the MASSIVE series finale.......how EXCITING!!!
