The Sorting and the Feast

This is part one of a series of how the Marauder's story would be different if Sirius and Lily would be siblings. DISCLAIMER: I know that Orion and Andromeda were not siblings, it's just part of the story. Includes Jily and light WolfStar. Another Disclaimer, I forgot to put it in last time. I do NOT, under any circumstances, own Harry Potter.
