Carter/Mckay/Keller fanfic idea. What would have happened if there was no rope for them to find and they had to do as McKay suggested of striping down to their underwear to make a rope out of their cloths. A adult story is preferable but not required. Thanks to anyone who takes up this challenge.
10,000 years is a long time to be alone, and to be alone like that can drive a person or city to insanity. This is where Atlantis is not just a city. Her time alone drove her into insanity and when the expidition arrives she takes the ones with the gene along with her. It can either be gradual or all at once but gene or not Mckay must be driven insane with the carriers. He and Sheppard are the cities 'favorites'. It can McShep. Bonus points to whoever can make it mostly cannon up until the ancients try to kick the expidition from Atlantis.
This is for a threesome Atlantis/Sheppard/Mckay which is not nearly common enough.
