This'll probably come off as a little incoherent.....

but it's been..... years, and my memory is unreliable at best. I'm looking for a fic (might have been a series even) that was sort of a Stargate/Supernatural fusion. Carson had some sort of special power (seventh son of a seventh son maybe?, I think Teyla was a dhampir, and McKay turned out to be an angel.

The only point is that I'm sure McKay was secretly an angel.

It's not a lot to go on, sorry - let me know if it rings any bells.
