Harry and Jamie Potter were born on the 31st of July in St. Mungos. Harry the eldest was born not making a sound, he just smiled up at his parents who cooed at him. Harry had deep ebony hair, and killing curse green eyes, while Jamie the younger twin who was a loud crier and spoiled by his parents had red hair like his mother and hazel eyes of his father. When Albus Dumbledore tested their cores he found that Jamie had a powerful magic in him, but when he tested Harry he saw he didn't have a core, and declared him a Squib. If he were to look a little closer he would notice that the reason Harry didn't have a core was because he was literally made of magic. Because of that simple mistake Harry was not equal to his brother.
On Halloween one year later a man crossed into Godric's Hollow silently. His cloak billowed behind him, as he came to the Potters house, wand in hand he blasted open the door unintentionally knocking one James Potter unconscious. Lily Potter screamed at the sight of him and hurried up the stairs. Just as she reached the door to the nursery a stunning spell hit her in the back. The cloaked man marched up the stairs. As he entered the nursery, he saw two children the first was crying loudly, red in the face. The man called Voldemort sneered at the crying child and turned to the second. The killing curse eyes glared up at him unafraid, and intelligent. Unlike Dumbledore, Tom Riddle felt the boys magic, and he lifted his wand and said two words, "Avada kadabra!" the acid greed light flew from his wand and towards Harry Potter, but just as it hit him, it bounced off and hit the man in the chest turning him to ash. The house rumbled from the backlash, The ceiling falling down on the children, marking one Jamie Potter with a 'V' shaped scar on his cheek.
Only minutes later the Order of the Phoenix arrived and Lily and James awoke. They rushed upstairs, Dumbledore, Sirius Black, and Remus Lupin rushing bebind. Dumbledore checked Jamie Potter and upon seeing the scar, he announced, "Jamie Potter has defeated Voldemort, " there was a sharp intake of breath, "he must be trained, for when Voldemort returns." And they walked out with the children in tow. If one was to look upon Harry's forehead they would have seen the lightning bolt scar, and the dark magic within. Thus a mistake was made the would change the past, the present, and the future for better or worse, who's to know?
