I saw your post about Charlie! It is better than mine, actually, I think, because mine is perhaps a little too meta.

And yes, SPN IS hard on its ladies.

Jo/Charlie was one of the pairings I could write for the femslash exchange, and I did sign up for it, though I didn't get matched on it. Most of the femslash pairings were women that had never met in canon, and a lot of them has one character dead and one character living so it was a challenge for sure!
