A/N: This would all be happening at the beginning of the sixth book, after their fifth year at Hogwarts, and the events at the Ministry.

"Hermione?" Ron Weasley asked cautiously, "Hermione, what are you doing?"
The young witch turned around giddily, acting uncharacteristically giggly and sloppy.
"Are you drunk? Harry, get in here!" Ron chuckled, surprised by her behavior.
Harry stumbled in from another room in Grimmauld Place. They had been lying around the Burrow with nothing to do for the past few weeks, so Harry came up with the idea of going through Sirius' old stuff. Mrs. Weasley reluctantly relented after Remus Lupin and Kingsley Shacklebot agreed to take the three of them using sidelong apparition, and that, seeing as Harry had inherited the house, a safety spell had been cast upon it by Dumbledore. The bored teens had hurried in, with Lupin as their chaperone, and quickly set to gathering up as many things as they could within the allotted three hours. What had seemed like a daunting task when they had first entered, the house feeling even more eerie than ever without the loud laughs of the Weasley twins and the arguments of the Order, had quickly changed tones. Harry, Ron and Hermione settled down after only fifty minutes, and they had separated into different rooms to sort through the dusty affairs.
"Is everything going alright up there?" called up Remus. He had been acting oddly bemused the whole trip, although the trio had marked his off smile up to sadness for his loss. It had only been two months since Sirius had been murdered, and Harry had been taking it particularly hard. He had formed a bond with Sirius that neither Ron nor Hermione had experienced, so this trip was markedly difficult for him.
Harry had still been thinking about the events of that fateful night, and his short few years with his godfather when he stepped into the room. Hermione's odd behavior brought him out of his reveries, and made him feel slightly better about being in Sirius' house, and he let out a slow laugh.
"What did she drink Ron?" he asked, "And we're fine Remus!"
"I haven't done any such thing!" giggled Hermione, her cheeks flushed, "I've only just opened this box, and when I picked up this book" she stopped, falling onto the floor with huge guffaws, as she gestured towards a small book "and when I picked it up to read it—"
Ron leaned down to pick it up, but before his hand could touch the book, Harry exclaimed, "Ron! Really? Look at the state Hermione is in. We hardly need two incapacitated wizards."
"No fair Harry…" Ron said, as he leant back reluctantly, "why should she get all the fun?"
During this time, Hermione had been shuffling through the box. Harry picked up the cover to look at it, and when he saw what was written, called down to Remus. When the older wizard stepped through the door, he chuckled at the sight before him.
"You're not angry?" Ron asked, "She's acting barmy! She's acting, well, drunk."
"Don't worry," Remus smiled, "I know what is going on. I… Well, I remember this."
"Remem--?" Harry wondered aloud, when at that moment, Hermione, her fist around something in the box, popped out of sight.
"Hermione!" exclaimed both Ron and Harry, reaching towards where she was.
"But—she hasn't gotten an apparition license yet, has she?" Harry asked, turning to Remus, who had remained calm throughout the commotion, "And what do you mean, remember this?"
"Those are our things," Remus explained, gesturing to the box, "The Marauders'. Back in our sixth year, we thought we were going into the magical pranks business, you know, selling things, like your brothers Ron. She picked up the 'Booze Book' and then, well, she touched the 'Time Trinket.' A bit like a port key, I suppose, although instead of taking her to a different place, well… I suppose the name would explain it."
"So that's why you said you remembered it…" said Harry, "she went to the past didn't she! Your past. How… When?"
Remus only smiled, and walked out of the room.
"I think someone is at the door downstairs," he said, and left Harry and Ron, mouths agape.
Review, the chapters after this will be longer, don't worry!
