Doctor Who Ideas.

Ok so as of "Lets kill Hitler" this is what I think:

River doesn't kill the Doctor, or should I say she isn't the one in the suit. I think its got to be a better twist. I was actually thinking Amy. As for the weird eye patch lady it does infer in the trailers that River is her but that doesn't make sense, they aren't the same person and River used up all her regeneration's on saving the Doctor. As for finding Lil River I think they pretty much have too. If not Amy and Rory will be pissed. However we know River grows up with Amy and Rory so that kindof fouls things there. One thing I noticed was that Sweetie is something that River gets from the Doctor that he gets from her so that's funny because neither of them invented it. Same weird thing also with Mel- Melody, the doctor even remarks "You named your daughter after your daughter.". I think this whole past effecting future effecting the past theme is going to continue and maybe even be at the center of the whole plot. Some people have been speculating that River kidnaps herself but I don't see who that could work at this point. I feel like Rory is going to be at the center of this whole thing, he hasn't had his own story arc yet and Rory's character has been developed so nicely it would be a shame to let it go to waste.
