"Raising Harry"
What if Severus Snape and Sirius Blake crossed paths at the Potter's house right after the death of Lily and James? What would happen if they decided, because of the loyalty and love for their friends, they decide to raise Harry themselves?
It'd be a little bits of Raising Arizona, Three Men and a Baby, Life As We Know It and a smidge of My Two Dads.
By their clothes it looks like they have most likely gone to live in some far off Muggle community, quiet possibly some where out of Britian. Possibly Canada, Greece or New Zealand. Maybe they travel to all three before Harry inevitably gets his Hogwarts Letter. Perhaps Remus joins them at some point? Or remains in England as their Secrete Keeper? Or is left as much in the dark as everyone else when it comes to their where abouts? What happens to Kreacher? What does Dumbledore do about it?
I haven't the foggest! XD
