Didn't come out quite as well as I wanted.

“Have I got a prank for you, Harry,†Ron whispered over the loud mingling of the new first-years waiting in the entrance chamber to be brought into the Great Hall.
“Oh?†Harry raised an eyebrow. “Do tell, my dear chum,†He was happy Ron was Awake this loop, it had been a few times around since the redhead had been so. The man had come a long way from the behavior he had in his very first lifetime.
Ron just shook his head, a smirk coming to his face. “You’ll see. Not very long now.â€
Harry wondered what Ron might have done, and if it was perhaps something even he himself had not done in a loop Ron was not Awake for (and thus unaware he might be copying Harry).

Shortly after the conversation between the two old friends, the ickie firsties were brought into the Great Hall of Hogwarts, and introduced to the Sorting Hat, the mechanism by which they were to be sorted. Only Harry saw the small twitch of Ron’s fingers, a telltale mechanism he was doing magic of a sort.
“When I call your name, come up and put the Hat on your head,†McGonagall declared in a loud voice that cut through the excited chatter of those who were to be sorted. “Abbot, Hannah!â€
A cute blonde whom Harry knew to grow up with a curvy body (and a delicious bosom, though not as enormous as her friend Susan Bones) went up, nervous an shy at being the first to go up.
With little pomp, she found herself seated on the stool and the Hat on her head. And then the Great Hall waited. And waited. Almost five minutes passed before the Sorting Hat shouted “SLYTHERIN!â€
Light applause came from all four tables, three of them disappointment at not getting the first new student, the fourth because raucous cheering was unrefined and under their standards. The pale Hannah slowly walked over to the Slytherin table, quickly seating herself next to another female who looked barely older than Hannah herself, possibly a prior acquaintance of sorts.
Harry let out a quiet hum of contemplation. Even slight changes in how he acted on the Hogwarts train prior to his First Year sorting could usually bump a few people around from their usual House placements, and even then there were often pre-existing changes that went further back in the timeline. A particularly common happenstance was Neville being Sorted into Hufflepuff. But what had occurred to put Hannah into Slytherin, of all Houses?
“Bones, Susan!†McGonagall announced, and the ginger girl who Harry had known in the Biblical sense far too many times to count (a goofy grin went across his face at the memories) went up, far more dignified than the first girl.
It took several minutes again for the Hat to sort her, until it again declared “SLYTHERIN!â€
Harry furrowed his eyebrows as he watched Susan move to the table of silver and green, cosying up to Hannah. He could never think of a Loop where Susan and Hannah had both gone into Slytherin. Two could be a coincidence, but three…
It took four, after the sorting of Terry Boot and then Mandy Brocklehurst into Slytherin before he turned over to Ron, and whispered quietly under his breath (with a Charm placed to ensure there were no eavesdroppers, of course), “Ron, you’re a bloody genius. I never even thought of that.â€
Ron just beamed in return. “I know,†He said in response to the genius comment.
It didn’t take long for the rest of the Hall to understand what was going on, as both Lavender Brown and Millicent Bulstrode were both sorted into Slytherin, followed by Michael Corner and Stephen Cornfoot. There could only be so many people Sorted into one House in a row before suspicions were aroused.
Harry watched with amusement as the Staff Table began to look panicky. It was a good thing Snape wasn’t Awake, he mused, because he looked like he was about to have a coronary. Even the normally composed McGonagall looked flustered as an unAwake Hermione, as loud and Muggleborn as they come, was Sorted into Slytherin.
It was with less than ten students left that Harry heard his own named called, and strode forward to put on the Hat. Unless Ron intended to prank him by putting him into a separate House, he already knew where he was going.
Ah, not just a time traveller, but somebody who’s existed nearly as long as the universe itself.
Hello, Mr. Hat, Harry responded in favour, having had conversations like this many times over. How aware are you of what you’ve been doing in the last two hours?
Very aware, Mr. Potter, the Hat responded, Of course, I cannot go against the enchantment your young friend Ronald put on me, so of course you will go into Salazar’s house. Not that you need much convincing, by the looks of it.
Of course not, Harry responded, But how do you convince the other students?
The Hat gave what Harry always interpreted as a mental scoff. It is the rare person who has no ambition, no cunning. Just for her desires to learn alone, Miss Granger for example could always have been sorted into Slytherin. Mr. Weaseley’s enchantment is rather clever, as I find myself making subtle, insidious arguments to sway them into accepting Slytherin House. Of course, the Hat paused, After the students saw everyone was being Sorted into Slytherin, they expect to be similarly Sorted, and so it is less an effort.
Ah, Harry thought. Well, it was a good conversation with you, Mr. Hat.
The Sorting Hat concurred, You too Mr. Potter. Have a good life in “SLYTHERIN!â€
More quiet applause came. In another lifetime, Harry Potter being Sorted into Slytherin would cause chaos, and newspaper headlines. Here, it was already expected.
Only a few more students were left to be Sorted. Ron had a long, ten-minute Sorting, picking up interest from other students when almost everybody else after Kevin Entwhistle had been sorted in two minutes or less. Even he was eventually sorted into “SLYTHERINâ€, with Blaise Zabini being the fortieth new student to enter Slytherin House that year.
“It’s a good prank, I’ll admit,†Harry mentioned to Ron as Ron found a seat next to him. “Any particular reason why, however?†He asked, as Dumbledore went through a very quick speech, before him, Snape and McGonagall all ran out of the Great Hall with the Sorting Hat, clearing in a panic over the proceedings.
Ron shrugged. “I wanted to see what the reaction would be from the public if everybody in a year was in Slytherin. Chaos amuses me. Besides, “ He smirked, “Dumbledore always talks about interhouse unity and all that. It’ll be hard to do that in six years when there is nobody in the other Houses.â€
