John/Rodney - Blast from John's Past

[scarletfbl.livejournal.com]

This is sort of a continuation of my post over on sgastoryfinders, here. Whether imagined, or not, the idea's in my head, now, so I'm running with it.

I'm looking for fics where someone from John's past shows up on Atlantis, and Rodney is insecure because he feels like John was only putting up with him/their friendship because they're stuck out in space. OR Rodney could be jealous [because he imagines] that the person who's come back into John's life wants him back.

Bonus points if the old acquaintance actually used to be John's lover. Male or female, it doesn't matter.
