It all started with a potion going wrong. It was neither Neville's nor Ron's nor any Gryffindor's fault. To Professor Snape's annoyance, it was the fault of a Slytherin. It was Nott's fault. The incident in question? Harry James Potter was turned into a girl by Nott's faulty potion. Harry at first wasn't really angry that it happened, he, or now she, only started to ask Peeves to annoy the hell out of Nott when Snape and Dumbledore told her that the potion can't be reversed, as no one knows what exactly had gone wrong.

So Harry was stuck as a girl, for probably forever. Her new name being... not decided until Halloween 1993, over a month after changing. She choose Primrose to replace Harry, The reason being that both his mother and aunt have flower names, so maybe it is some kind of Evans family tradition? And she likes the name. First rose, Primrose is the first one to change their sex.

James became Lily. Yes, she replaced the parent. She was considering changing the middle name to Jamie, but Jamie felt incomplete. Albeit Primrose felt bad that none of her given names hints at her father. Well, you could argue that the surname does.

The new Primrose Lily Potter adapted with ease to the new life. Until Lavender and her friend Parvati happened. The girls decided that Primrose's hair needs to be made pretty. Despite everyone being scared about Sirius Black, Primrose was more bothered with Lavender and Parvati sneaking up on her and trying to style her hair. Which is difficult, now that Primrose is in the room of the girls.

Hermione didn't really help. She said this was her problem.

"I had to live though this, now you have to do it, too.", was all Hermione said. "See it as a hazing ritual."

"To the room or to being a girl?", asked Primrose nee Harry.

"Both."

Primrose probably hadn't spend so much on the twin's prank materials or used the invisibility cloak so much. Lavender and Parvati will be the death of her. Good luck to top that, Voldemort!

One positive thing coming from this was his heightened awareness of his surroundings. While always keeping eyes open for Lavender and her can of hair spray or Parvati and her bewitched hair brush, Primrose's senses sharpened.

The only time when Lavender came close to ruining Prim's hair was around the ninth December. Oliver Wood demanded they fly in the snow to toughen up. Lavender was waiting for Primrose to return. She was sneaking up on her walking into the sleeping room like an apex predator. With the difference that this apex predator's pray jumped out of the window, broom still in hand, flying off.

Primrose left behind a little something build by the twins, as payback. While Lavender left Primrose's hair alone for a week, she was rather aggressive to the twins. Where her friend was in all of this? Parvati spend time with her sister Padma.

Now, while Primrose adapted very well to the change, let's be real, after the shit from the last two years, Primrose stopped to care, the Dursley's were not taking in the news well.

"Do I understand you right, my nephew got turned into a girl in your freak school?", repeated Vernon. "From all the possibilities... I didn't expect that."

"No one did, Mr Dursley.", said Professor McGonagall. She volunteered to inform the Dursley's.

"What will the neighbours think that Harry is a girl now?", wondered Petunia annoyed.

McGonagall sighed. While it won't be correct to do, Primrose has to stay with them, so McGonagall better make it less worse for her student.

"While I am not a fan of lying, this is to protect the secret of the world. Just say Harry had a twin. Due to Harry's behaviour, he and his sister Primrose got send to different relatives.", proposed the Professor. "Tell anyone who asks that you couldn't handle Harry any more and switched the twin with the relative, who is more strict."

"That's quite the lie, Miss.", chimed Dudley in.

"Thank you for the compliment about my lying skills.", she replied nonchalantly.

"That lie could work. If Harry-" "Primrose." "Plays along.", said Petunia. "Did you have to interrupt me?"

"You got your niece's name wrong.", was all Minerva said.

"What name did our niece choose?", asked Vernon.

"Primrose Lily Potter."

"That's not a bad name. Why that one?", asked Petunia.

"She chose Primrose, because it means first rose. Not only is your niece the first person to survive the killing curse, she is the first one to switch her sex."

"Didn't you freaks already figure that one out?"

"Only temporary solutions, Mr Dursley. Even magic has it's limits.", replied Minerva McGonagall. "She choose Lily so that she is still named after a parent."

"I assume she could have chosen something worse.", muttered Petunia.

Sirius was very mind blown when he realized his god son is his god daughter now. Remus was already accepting it. Peter Pettigrew already knew of it, so he used Sirius distraction to take his leave.

Back at the Dursely's place, Primrose had to adapt to a few changes. On the way back, her aunt briefed her on the lie she and McGonagall came up.

"Play along with that story of ours, understood?"

"Yes, aunt Petunia."

Apparently the change in sex motivated them to buy Primrose some stuff. A heaven of clothes for Lavender, albeit still cheap, but a nightmare for Primrose.

Last but not least, Dudley was banned from bullying Primrose and he really was fighting the urge. He found a valve for that urge when some of his friends and acquaintances started to flirt with his 'hot cousin Primrose'.

For the first time in years, the cousins agreed on something. "Ew."
