I really enjoyed this one:

In 2004, Castiel watched the Apocalypse end disastrously and makes a decision. In 1984, John Winchester suddenly finds himself with another little boy, one with dark brown hair and sad, blue eyes who won't leave John and his sons alone. And so Sam and Dean get a weirdo big brother. Because both of their lives aren't complicated enough.

Time travels obviously, really cool story. Hope it helps ya!

that fic just got rec'd to me in the other thread! what a coincidence. xD it seems to be famous here so i'll check it out, i'm just hesitant on the jimmy part if there's much focus on him in the fic since i don't really care much for him as a character.

thanks for the rec! :)
