I read this one really amazing fic that explored "what if Kavanagh hadn't fainted before being tortured in Critical Mass?" . It was very well-thought-out and I loved it, BUT it had a slightly OOC Dr. Kavanagh, making him an angry, angsty sort. I'd love to see someone try this idea with a canon Kavanagh--a weak, petty person without much spine, but whose motives are ultimately good. You could have him taking medication to prevent the fainting or whatever. Just don't make him grow a spine and keep him in character as much as possible. If you can add some believable Kavanagh/Weir, I will be awestruck and delighted, because I love impossible pairings. Guilt or pity inspiring her to finally treat him differently is just fine. Failing that, any other pairing is fine too. Pretty please?
After season 4 and Atlantis is back in Pegasus. Jack is leader of Atlantis. A Christmas one where Aiden and an original character take over Atlantis to save Aiden's son. There must be Sheppard/Teyla and Jack/Sam.
After the events of Tabula Rasa, Keller realises some of the drugs given to the military to stop the amnesia haven't been returned. Sheppard then discovers that a certain Major has become addicted to the drug. Can be Sheppard/Lorne slash or friendship. Some McKay snark would be lovely too.
