Hey. New to the community (nice banner!) and am looking for a certain kind of fic b/c of a fanvid I saw.

Basically, a crossover where John fathered another son either before he met Mary (Angel - Wesley) or after he lost her (Buffy - Xander) and the boys find out and meet their long-lost kin.

Prefer Xander/Spike and Dean/Castiel when doing slash pairings. NO incest, please.

Thank you very much.
