So last night, I posted this little spoiler for all of you: "So the Doctor, Amy, Rory and River returned in 6.08 episode of Doctor Who entitled "Let's Kill Hitler" where they don't whack the awful German Dictator from World War II but save him, mistake!!!!!!!! And insane part happens when River shows up....."
Yes, in last night's episode that was not so appropriately titled "Let's Kill Hitler" was a whirlwind of craziness packed into a hour. Amy and Rory call the Doctor via spelling out his name in a corn field, he answers and they are shortly joined by Amy and Rory's friend Mels. Now here's where it gets interesting. Mels is actually Melody/River and Amy named Melody/River after the person she thought was her best friend but was actually her daughter in one of her regeneration stages. Mels then later on regenerates into a young or semi young version of River who doesn't know she's River and still goes by Melody. Melody/ River then kills the Doctor in Hitler's office while Hitler is being kept in the cupboard by kissing the Doctor with this fatal lipstick she's wearing. But don't worry fellow Whovians, as you know if you've been paying attention since season six started this isn't where the Doctor dies, remember Utah in the premiere. So with that said, towards the end of the episode Melody while still trying to figure out who River is saves her parents and then gives all her remaining regeneration lives to the Doctor thus bringing him back to life (at least until Utah) and begins her stint in recovery in the hospital where her parents and the Doctor leave her and the Doctor leaves her with her diary that we always see her with. Now the episode ends with River knowing that she is both Melody and River and she has the diary with her at the Lunar University in 5123 discussing with a Professor about getting into the school's archeology program due to the fact that she is looking for a "Good Man." ie the Doctor and the whole possible throwback to episode 6.07. Well anyway until the 13th episode, River; Be good and we'll see you then.
