Jeannieverse idea- cons

Jeannieverse AU in which she's a criminal and knows Neal Caffrey or someone in Leverage- or one of them is one of the Atlantis kids all growed up (Elliot?).
Or _Neal_'s one of the Atlantis kids and one day she comes strolling into the FBI and starts reaming him out for not keeping in contact and they've been worried sick and how could he be so stupid and etc. He edited the DNA and fingerprints in the SGC files so his wouldn't ping them. And everybody's like "WTF?" and Peter's like "Hands off, he's mine!" and Neal's...cowering, maybe? He knows charming her won't work. Maybe yelling back or something else. She might be there to work together on a case. If he's not really Neal Caffrey, but actually a Sheppard-McKay...that explains so much.

White Collar (/SGA)

Earth's about to get destroyed or become uninhabitable so they start to evacuate even though they know they won't be able to save very many people. Neal, Peter, and El (and possibly others) are among those lucky enough to escape, but something goes wrong and they end up without official leadership or transportation and have to use all their skills to survive and make it to Atlantis. Doesn't have to be a SGA crossover, I just thought Atlantis would make a nice concrete destination that would be difficult to get to.

Preseries, when Peter's still chasing Neal down and doesn't want to work together.
