Rose Potter and the Boy-Who-Lived
by coolhacker1025
This is a crossover between my "Rose Potter" stories (preferably "The Adventures of Rose Potter") and semi-canon (EWE, no-Cursed Child, HHr) Harry Potter
"Hermione, look at the Map," said Rose, whispering, as she didn't want to reveal the existence of the Marauder's Map. "Someone by the name of 'Harry James Potter' is in the Forbidden Forest."
"Who's he?" asked Hermione, curious.
"No clue," responded Rose. "Everyone says that I'm the last Potter. I'm going to go check it out."
She headed towards the door.
"Hang on, Rose," said Hermione, jumping up. "Someone has to make sure you stay alive."
"Just be careful, Hermione," said Rose as they exited the castle. "One threatening move and you take him down hard, okay?"
"Got it," said Hermione. Rose put her finger to her lips to tell Hermione that they should go in quietly.
Soon, they sighted what appeared to be a male, 15-21 years old in a clearing.
"Identify yourself!" commanded Rose.
"You don't recognise me?" asked the boy. "I'm Harry Potter."
"Who?"
"Harry Potter, The Boy-Who-Lived?" said the boy. "I can tell I'm at Hogwarts, but what's the date?"
"The Boy-Who-Lived?" asked Hermione. "There's no such thing."
"The date?" asked Harry.
"The First of November," said Rose. "Do you want to tell us who you really are?"
"I'm Harry Potter," he insisted. "What's the year? Major events?"
"It's 1994," said Rose. "Blimey, how many have you had? We just had the selection for the Triwizard Tournament last night, and my name came up as the fourth 'contestant'."
"I recognise your companion, it's nice to see you, Hermione, but who are you?" he asked Rose.
Echoing his previous statement, she said, "You don't recognise me? I'm Rose Potter, the Girl-Who-Lived."
"That explains the time difference," said Harry. "If today's the first, that means that it's a...Tuesday. Why don't you meet me in the Shrieking Shack tomorrow, say 16:00, and I'll explain everything."
"How do we know that you're not going to rape and/or kill us?" asked Hermione.
"I, Harry Potter, swear not to harm Rose Potter and Hermione Jean Granger at our meeting tomorrow," he said. There was a flash of light, as magic accepted his vow. "I also swear that I am not your enemy, and that I don't follow Tom Marvolo Riddle, the dark wizard who calls himself 'Voldemort', nor do I support him or his ideals."

"Who do you think he is?" asked Hermione. "I mean, he has to be an imposter of some kind."
"There is the possibility that he is telling what he believes the truth to be," said Rose. "You're always talking about science fiction shows your dad watches—maybe this guy travelled dimensions or something."
"Did you see what he looked like?" asked Hermione. "Or rather, who he looked like?"
"He looks like dad, except with mum's eyes," said Rose, who had often heard the exact opposite said about her. "He seemed to know you."
"Which would seem to confirm your Dimension travel hypothesis," said Hermione. "We just need to be careful."
"We're not telling anyone else about this, right?"
"Right," said Hermione. "Did you think he was good looking?"
"Nah," said Rose. "Not my type. Plus, with the way he looks it would be like a reverse Oedipus Complex. You?"
"Nor mine," said Hermione.

They met Harry at the Shrieking Shack the next day. He was already there, waiting for them when they showed up. He held up a vial of a clear liquid.
"Do you know what this is?" he asked. Hermione put her hand up like she was in class, and Harry pointed to her.
"That's Veritaserum," said Hermione.
"If I were a teacher, I'd award five points to Gryffindor. I will take it if you have any doubts about the contents of this," said Harry, pointing towards a stone bowl. "And I'm sure that you recognise what this is?"
"That's a Pensieve," said Hermione. "It lets you organise your thoughts. Aren't those expensive?"
"Very," said Harry. "Which is why I've 'borrowed' this one. In this Pensieve are my memories; if I am where I think I am, then Rose should recognise at least parts of some of the memories. And another imaginary five points to Gryffindor."
He then guided Rose and Hermione through his memories, and a while later, they emerged.
"You're me," said Rose. "Except for a couple differences, including the glaring one."
"Did your Sirius never get free, Mr Potter?" asked Hermione.
"Hermione, don't ever call me Mr Potter," said Harry. "Call me 'Harry'. I'm going to change my last name soon, anyway. Keeping the name 'Potter' would cause too many complications. No, Padfoot never got free."
"I think that we need to get you caught up to us, as well," said Hermione.
"How do we do this?"
"Put your wand to your head, and concentrate on the memory," said Harry.
After a number of memory extractions, they dove back into the Pensieve again.
"Okay, so first year is mostly the same," said Harry. "Except you were more suspicious of Quirrell, you met Hermione before school, and you're a bit more bookish. You also managed to befriend Neville a whole lot easier than I did."
They jumped in again, and Harry was furious when he saw the results of her second year, saying things about the Dursleys that he would never say in front of Mrs Weasley.
"They beat you half to death!" he exclaimed after he mostly got calmed down. "At least your friendship with Neville counted for something. Dowager Countess Longbottom is a wonderful woman, letting you stay at her house, and convincing Dumbledore to let you do so."
Naturally, Harry went on another tirade against Lockhart, as the man had acted even more poorly in this time. He laughed at the new duel at the Duelling Club.
"I love the way that Flitwick took care of Lockhart," he said. "And then, that was a magnificent duel between him and Snape. I wish the Club would've been more like that during my time at the school. But how dare he attempt sexual relations with a student—an underage student, at that! King was a great teacher for the rest of the year.
He then commented on Rose's reaction to Hermione being Petrified. "Definitely seeing the Evans temper there," he said.
He then mentioned that Rose had done things nearly the same way he had, with the obvious exception of no Lockhart, but had managed to get the Headmaster to tell her a lot more about Tom.
"Probably, Dumbledore is feeling a bit guilty about your…er, stay at the Dursleys," said Harry, before moving on to third year.
Rose's third year was as much the same as it was different. This was because Rose had a different perspective on the "Black escapes Azkaban" thing.
"Real clever, how you unintentionally outed Wormtail," he commented, spitting on the floor. "Much better perspective, as 'Gran Longbottom' seemed to know the Potters, and therefore the Marauders. Also, good job on forcing Hermione to take fewer classes."
That earned him a half-hearted glare from Hermione.
"Rose explained it well," he said, defending himself. "My Hermione didn't figure it out until she had driven herself mad from overwork, due to over-usage of a Time Turner. Like she said, there is no science to divination and the Muggle Studies class is miles out of date."
He continued with, "Good job with the hippogriff. I didn't realise until much later that Hagrid's class was a bit inappropriate, though. Hippogriffs are generally a sixth or seventh year creature."
Harry didn't really need to mention that before Hagrid, that's what year they had been taught in.
"Great about Padfoot getting free," he said. "He was only cleared posthumously in my dimension."
"Where did he stay until then?" asked Rose.
"He went to the Caribbean and Majorca for a while after the Incident at the Shrieking Shack of '94," responded her male counterpart. "During my fourth year, the Triwizard happened, and he was in a cave in Hogsmeade for a year, before returning to his ancestral home."

They soon finished reviewing the memories, with Harry taking note of the changes that had occurred to the timeline.
"Honestly, not much has changed," said Harry. "But, for the most part, the changes are significant."
"So, what are you going to do here?" asked Rose. "I'm sure you don't find us attractive."
"No, I don't," said Harry honestly. "First off, you're 14 and I'm 22. Big age difference at this point. Second, Hermione is slightly, but significantly, different from the Hermione I knew. Lastly, you look like my mother, Rose. I don't want to be accused of being a paedophile with an Oedipus complex."
"So what are you going to do?"
"There is a little known part of the Hogwarts Charter: Section 94, Subsection Baker," said Harry. "It allows any student to retain, at their own expense, a tutor for any subject or subjects, as long as the tutor is registered with the Ministry of Magic. Not many people remember that section, but it's there. I was thinking that Professor Harry Evans could teach you about Wizarding Law and History of Magic."
"Evans? Like my mum's name?"
"Correct," responded Harry. "Apparently, the Evans were a small family that slowly died out. Your grandfather's grandfather was a Squib. I'm going to need to borrow the title of Lord Evans, and about ten thousand galleons, plus the 500 galleon deposit for attaining my title."
"Will that work?" asked Hermione.
"I'm related to the Evans family so, yes, it'll work," said Harry. "And since I am male, I probably have a better chance at the title than Rose does."
"Do I have ₲10,500?" asked Rose. "Other than that, you can have Evans and Potter if you like."
"I'm leaving Potter for you—or more accurately, your descendants," said Harry. "You'll need to make sure one of your children has the name 'Potter'."
"And the money?"
"Last time I checked, in 1994, you were making about ₲50 interest at 0.06% APY per day," said Harry. "Next weekend is a Hogsmeade Weekend, so just have Padfoot write a letter authorising you to go to Diagon Alley Gringotts with me."
"Where are you going to live until then?"
"I'm going to Padfoot's house and telling him the story of the biggest prank ever pulled," he said, laughing. "He'll let me in. Now, you should get back to your Common Room before you are missed. And don't stop at any Broom Cupboards on the way!"
"Harry!" exclaimed both of the girls.
