Jason had thought that his life was already strange as it is, but after what had happened over the past several months had taken the cake. First off, Bellatrix had made him her son at the bank called Gringotts before having her original name changed to Bella Stella Black. He found out later that her husband was dead and the marriage contract was void when he died because of a certain loophole left by her father, saying if she didn't have any children when Rodolphus died, she was free of the Lestrange name.
Jason also had his name changed to Jason Voorhees Black, though the goblins protested to this because he had other names and titles that came from his original name. Bella had asked him what he wanted and with some pointing and a few ink bottles so he could write with his finger on paper, he had his mother take other the other names and things. He wasn't going to let this place hold him from his real home at Crystal Lake, Bella had agree to move there after he had finished with his business here in England.
His mother also got his ability to return from the dead after someone had 'killed' her with their 'wand'. Jason had killed the man that hurt her before carrying his mother to a safer place. Bella returned to the living faster than he did after 'dying' for the first time, so they couldn't be separated by the scythe of death anytime soon. That was also the day that Bellatrix Lestrange was pronounced dead by the goblins and Ministry and Bella Stella Black was born. Magic was strange sometimes, but it explained something's about his 'supernatural' talents.
His ability to teleport, use the Lake Mist or any mist for that matter for short teleports as well, his machete being able to return to his hand, all of that was done by his magic. The unnatural regeneration and returning from the dead however was not explainable and he didn't care.
"Jason, please don't kill Mr. Ollivander. He's the only wandmaker that makes wands for Hogwarts firsties, but I'll allow some roughhousing if he provokes you." Bella said, Jason nodded to his mother before opening the door and allowing her to go first.
Entering the building, Jason looked around and saw shelves that reached the ceiling that had boxes in every one. "Ah, I was wandering when you would enter my shop, Mr. Potter. Or should I say Mr. Voorhees-Black?"
Jason whirled and paused as he found a white haired but energetic man smiling at him. His mother was also looking at the man with a dark look, but the wandmaker apparently didn't notice or ignored it.
"Mr. Ollivander, my son and I are on a tight schedule so can we move on to the wand search?" Bella said crisply, her tone cold.
"Of course, of course! Just one moment." Ollivander said before disappearing into the back then returning to the front with an old box. "Douglas Fir with the hair from a black unicorn's mane, 9 inches and very picky."
Bella picked it up and smiled as the wand in her hand glowed, "This is the one."
"Yes, a good match, now onto-" Jason pulled out his machete and placed it on the cabinet, the metal glinted in the candle light.
Ollivander's eyes widened in shock as he picked up the weapon and studying it with reverence. "Yes, yes, the perfect match for you."
"My son's machete is his 'wand'?" Jason's mother asked, surprised.
"Yes, your son's weapon is his foci. The metal is goblin silver that is infused with the scales of the elder dragons of old; the handle is Thestral and Unicorn leather that was dipped in the blood of a siren. Indestructible and very powerful, indeed. Where you found this focus, I do not know but it will serve you to the end of time, Mr. Voorhees-Black." Ollivander said his face as white as a ghost.
Taking his machete back from the wandmaker, Jason looked at his mother before turning to leave the building. Bella placed her hand on his shoulder; she paid the man for the wand then with a loud crack, apparated them back home.
Number 12 Grimmauld Place, London
The house of Black was silent as Jason walked down the stairs to the final landing; his mother was doing something that he didn't need to help with as it had to do with his 'other titles'. The machete wielding murderer had given those titles up for good reason, but he was still reminded of the pink haired girl that escaped him every sleeping moment.
He had to kill the girl, his mind wouldn't allow for anything else to stay in his head until she was no longer breathing. How he managed to keep himself from killing anything on sight was beyond Jason, as he usually didn't have this dilemma in the first place to begin with. He stopped walking, noticing an open door that had caught his eye.
He entered it and found a massive tree-like painting that was very old, even burned in some places. His eyes found the writing at the top of the tree that read; The Most Ancient and Most Noble House of Black, Toujours pur.
Remembering his lessons with his mother, Jason understood what the Latin meant, Always Pure. His finger traced the 'branches' of the tree until he found the name "Bellatrix Black", then watched as the name was burned off and another line appeared below it that read "Bella Stella Black".
A golden ribbon wove its way down so it was slightly beneath his mother's name and a red and black line connected from her name to the blank ribbon. Jason placed his finger on the blank ribbon and pulled his hand away as pain hit him. He looked at his finger before looking back at the tapestry and froze, his name was being written on the blank ribbon.
The name read: "Jason Voorhees Black/Harry Potter-Gaunt-Peverell-Black, Mors Vincit Semper." He translated the Latin and read "Death always Conquers". Oh, how true that statement was…
Jason stopped looking at his name and noticed something odd, next to his mothers' burnt name was two other ribbons, one read "Narcissa Black" and the other was burnt off. He followed the burnt ribbon's line and found two other burnt names; confused at why this was he pulled out his knife and used the repairing charm his mother taught him.
The names repaired themselves and Jason found out why. The burnt name next to his mother's own read "Andromeda Black" and that was connected to the name "Ted Tonks, Mudblood". Connected to them was the name "Nymphadora Tonks, Metamorphmagus, Mudblood". Why did these names have more than the others and what was a metamorphmagus anyway?
"Master Jason called Kreacher?" Jason turned and gave the old house elf a pointed look; the housekeeper had somehow heard his questions and appeared.
Jason pointed at the word he was confused about, the house elf looked at it and said "Shape changer, blood traitor is able to change shape at will, Master Jason."
A shape changer, Jason's memories of the girl that escaped him entered his mind. He DID see the hair of the girl change from pink to a sickly green on that day and now he had a name to go with the face. He waved Kreacher away, who vanished with a crack to who knows where and made his way towards the kitchen. He needed to make some mist; Jason was going to finish his purpose for coming to this place.
