I wish it were this easy before

It had been a couple of weeks since Hermione's birthday party and October was getting noticeably chillier as time went on. Things at Hogwarts had finally settled down into a routine that Rose could work her plans around, and she was genuinely enjoying school for once, easy as it was. Rose and Hermione had quickly been established as the top two students in the year even though Rose was dumbing down her work immeasurably.

She may be in a child's body but her analytical mind was one of the best Unspeakables in the Department of Mysteries, and it had been alluded to that she could have taken over in the next decade if nothing went wrong. (And when the Unspeakables said 'went wrong' they meant something like the situation she was in now; it was honestly a strange year if nobody disappeared or died in their department, and they always had to have numerous back-up plans for this very reason.) Her adult mind was now being forced to revise knowledge that was as simple as breathing so she literally couldn't act the same as before.

It only took a few metaphorical glances at her life for Rose to realise that she was changing things around her very quickly. She had already had the Horcrux in her head destroyed as well as the ones in the cup and the diadem; she had gotten a note from Sirius saying he would take the locket to be cleansed soon, and Sharpfang was readying a team to cleanse the ring as she spoke.

Sirius was free, Remus was living with them, and she was a 'genius' Ravenclaw. Snape hated her more than she thought possible, and Dumbledore had an automatic frown whenever she was around. If she wasn't careful something big would happen that would cause things to go horrifically wrong. She needed to stop Voldy's other possible future plans before they could take effect and cause her own plans to fold like a deck of cards.

Hence why the girl decided to remove one of the biggest threats in the castle. It was evening when she began to enact her plan, and Rose decided to wander around the castle for half an hour in seemingly random directions before seamlessly wandering into the corridor where a certain haunted bathroom was.

A quick check turned up no sign of Myrtle so Rose quickly set up some wards around the room keeping people out and some extra ones around the sink in case anyone ever figured out where the entrance to the Chamber of Secrets was.

She made her way to the sink and spoke to it softly.

§Open§

The sound of shifting stone permeated the bathroom as the sink morphed into a tunnel that was reminiscent of a cliché mystery story.

§Stairs§

Rose peered into the dark tunnel as the slick walls rearranged themselves into a set of stairs covered in centuries worth of grime which she removed with a quick Scourgify.

As she casually wandered down into one of Hogwarts' biggest mysteries she pondered Dumbledore and his knowledge of her Parselmouth abilities. He had been so sure that the skill was because of the Horcrux in her head, but she knew that if the soul fragment had been strong enough to make her a Parselmouth it would have been strong enough to fully possess her. She had an uneasy feeling that the esteemed Headmaster actually knew that it wasn't because of the Horcrux at all, and that he knew the truth about Lily Evans.

After graduating school and being able to walk into Gringotts without being threatened to death, Rose had decided to take an inheritance test that revealed her ability to speak Parseltongue hadn't been as random as people had thought, and that Lily Evans hadn't been quite as muggle-born as people had thought either. It seemed that a few generations ago Lily's great-grandmother had been born a squib and cast out of her family.
