It wound up being Sheppard/Teyla - for a while I wasn't sure if it was going to go friendship/gen - but not in a sappy shmoopy way, I don't think. Not that there's anything wrong with shmoopy. I love shmoopy. It just wouldn't have worked in this case.
Now I think I'm going to take a few hours off, watch the baseball game, clear my head of it a little, and then I'll go back and reread all 62 pages. That's right: 32k words. Makes this my longest SGA fic by far.
