Are there any stories where John's knowledge of the "other future" and Keller's death would play a part?

Last night I was having a bit of trouble sleeping and came up with some requests. I'm not sure if any of these exist, but id there's a place to look... 1. John getting kidnapped? 2. John having a male... xD 4. Sam Carter/Jennifer Keller/Katie Brown vs John Sheppard for Rodney's affections? 5. John and Elizabeth being siblings? Thanks to anyone who can find any of these... preferrable McShep. ♥

Looking for McShep stories in which Rodney breaks up with Keller. The reason isn't important; maybe they just break up, maybe he breaks up with her in order to be with John, anything. I know there are...where Keller breaks up with Rodney, but I'm looking for Rodney doing the breaking up. With the added bonus of the story ending McShep, or at least with the strong possibility. Please and thank you

Hello folks- I'm on the look out for stories where Keller is friends with McKay and/or Sheppard. To be clear, I'm not looking for McKay/Keller, but any other pairing- or no pairing at all- is fine by me. Thanks!

I'm in the mood for some specific types of Keller-fic: 1) Keller is evil/mean. 2) Keller dies. 3) General Keller whumping. I don't really care whether it's gen/het/slash, but I'm especially in the mood for mcshep.  Thanks so much!
