The Youngest Winchester(-Potter)

by AddyTonks957.42

What if Harry James Potter, the Boy-Who-Lived, was raised by Dumbledore (read House Elves) while his twin sister, Adeline Lilith Potter, was left with the Dursleys. What happens to Dumbledore's carefully calculated plans when Adeline decides she wants nothing to do with them? When she is more Slytherin than his plans had ever taken into consideration? And what about her brother?

AN: Updates will be inconsistent. I am still learning to use this site, so there will be problems. This is one of my first fanfics, so I hope you enjoy!

I do not own Harry Potter or Supernatural.

Dumbledore, Granger, and select Weasley bashing. Slight Harry Potter and McGonagall bashing.

Prologue: The Boy Who Lived?

Albus Dumbledore was sitting in his office, waiting for the alarm to sound that the wards around the Potter's cottage were destroyed, signaling that the prophesy had come into play. He had already figured out that Harry Potter was the boy the prophesy was referencing, as it couldn't possibly be the Longbottom boy. Neville Longbottom was nearly a Squib. It also couldn't possibly mean little Adeline Potter, as she was a girl. She also, unfortunately, didn't fit into his plans to mould her brother into the perfect weapon. She would have to go. Maybe to Lily's sister's house. Yes, a compulsion charm would be perfect. He could get the girl off of is hands while keeping his hands clean. And a compulsion on Sirius to find Peter once the Potters were dead... Yes, that could work. Get Sirius thrown in Azkaban, Peter labeled either a traitor or a savior, Remus unable to take custody, due to his condition, the Potter's dead, and little Harry raised as a spoiled brat who looked up to him.

Now all he needed was for Tom to mark Harry already.

As though like magic - and wasn't that a curious saying, what Muggles called magic was usually a mere coincidence - the wards dropped. Albus waited another five minutes to ensure Tom had marked the boy before apparating to what was once the Potter's cottage. He carefully picked his way through the wreckage to find the children. He took note of the body of James Potter at the foot of the stairs and that of Lily Potter next to the crib, her hair spread around her head like a pool of blood, as well as a pile of robes near the crib as well. He quickly scanned the children, Harry soundly asleep; no doubt due to magical exhaustion, he thought; and Adeline standing, watching him warily.

That's odd, Albus thought when he found nothing wrong with either. Neither of them have the horcrux.

He gingerly picked both remaining Potters up carefully and apparated to Privet Drive. He cast a quick warming charm on Adeline's blankets and left the letter he had written hours before nestled with her on the doorstep of 4 Privet Drive, knowing what was to come in the next years, hoping she would be dead before she was eleven.
