It was a regular day for James Sirius Potter. Prank, flirt, eat, sleep, wake up, eat, prank, flirt. The same thing over and over, and that was fine for him. He passed his friends; Rose reading one of her abnormally large books, Hugo playing chess against himself (which was really weird to watch), Victoire and Teddy holding hands and talking by the fireplace, Roxanne and Fred joking around with Scorpius, and his little sister and his little brother, Al and Lily, playing a game of Exploding Snap. They were all in one of the many living rooms in Number 12 Grimmauld Place that had been shaped up and made into a home for the Potters over the years.

James felt today-this innocent winter day-was the day he should break into his dad's office, to see if there was anything valuable or blackmail-worthy stuff in there.

"Jamie, what are you doing?" Lily called, her big brown eyes wide. This caused everyone to stop what they were doing to turn and look at James.

"Nothing, Lilypad," he replied calmly, "I'm just going to see if dad's in his office. I need to, er, ask him something."
"Really?" Teddy asked dubiously. The prankster tended to be an incredible liar, so nobody really knew if he actually WAS going to go ask Mr. Potter something or not.

"Yeah," nodded James. "I was going to ask dad if he, um, knew if Aunt Hermione and Uncle Ron would be coming over for dinner tonight."
Teddy, still suspicious, nodded. "Okay," he agreed slowly. James flashed a grin at his family and friends and practically ran out. He jiggled the doorknob to his dad's office. Locked.

James pulled out a small device that Uncle George was now selling at the joke shop: an Unlocker. He tapped the doorknob twice, and the lock clicked and the door sprung open. This really did come in handy for underage wizards.

"Dad?" he called, just in case the others had decided to either follow him or eavesdrop. He entered the spacious room, with a huge marble desk, carpeted floor and chandelier.
His dad's big leather chair was empty, and his desk's surface was hidden under piles of paper-being one of the best Aurors seemed to come with a LOT of paperwork. James prodded around with the tip of his wand, until he saw some papers on Kingsley Shacklebolt being the new Minister of Magic covering an object.

Curiously, James shuffled the papers off with as little paper-rustling as possible and saw a worn wooden box, holding a necklace. It had a label on it that said, A Time-Turner.

"A Time Turner, eh?" James grinned. He quickly snatched the box up and hid it under his cloak. He shuffled the papers back, looked around the room for any source of spying, and then sidled out, quietly shutting and locking the office door once more.

Back in the living room, James grinned.
"Hey, Freddie! Roxie!" he greeted his troublemaking partners.

"What did you do now, James?" Rose asked, looking up from her book.
"Nothing," James replied, insulted that she'd accuse him so quickly. "I looked for Dad and he wasn't there."
"So?" asked Roxanne. "What'd you find?"
James grinned again. "This." He brought the box out with a flourish. Everyone gasped.

"A Time-Turner? Like the one Aunt Hermione had?" demanded Al, his eyes squinting at it.

"Yes," nodded James. "It's even sparkly!" He opened the box.
"NO, JAMES!" shrieked little Lily, as he picked up the gold chain.

"NO!" everyone else yelled. Fred made a dive for James, knocking away his hand. The Time-Turner flipped through the air, landing on the wooden floor, the pendant part breaking off of the chain. The little hourglass spun and spun and spun...

"WHAT HAVE YOU TWO LUNATICS DONE?!" screamed Rose, as everyone in the room was sucked into a void of nothingness.
