It already took place in one of my older AU saga series fics. I apologize as I can't remember which one.. I'll have to go back and look to see which one it is...but yikes there's a lot.

I used to be able to keep track of it all in my head, but now there's too many. I have a habit of cross referencing all my stories to keep my universe consistent.

Will let you know which story it is when I find it. (chuckle)
