A/N: A reader commented that it's a bit confusing with so many different characters in this story to tell exactly who each character is and how they are related to Scorpius or Rose (especially the more obscure members of the Weasley family), and so I though at the start of each chapter I would just add a little description of who the character is to help clear this up.

Albus Potter: Rose's cousin, Middle child of Harry and Ginny

Disclaimer: I do not own Harry Potter

Albus knew that apparently he didn't know anything.

When Albus Potter heard that Rose Weasley was dating Scorpius Malfoy, he wasn't upset because Scorpius was a Malfoy. Albus was upset because Rose had lied to him.

Growing up Albus and Rose had done everything together. They had been born a mere eight days apart from each other and had been like two peas in a pod since birth. They had learned how to ride brooms together in the Potter's backyard. They had spent endless hours in their secret treehouse together. They had been partners in crime when it came to pranks to get back at James (James had been a prat even back then).

Even as they had grown older Albus liked to think that they had remained just as close. In Hogwarts they had both been sorted into Gryffindor. Together they had joined the quidditch team in second year, braved the shrieking shack during their first Hogsmeade visit, and spent endless hours exploring the castle after hours.

Albus had thought that out of all the people in the world he had known Rose best.

He had been wrong.

After the big revelation of Rose's and Scorpius' secret relationship all of Rose's lies to him had become glaringly obvious.

All of those times Rose had claimed to be "studying late" in the library had been spent with Scorpius.

That necklace Rose always wore had been a gift from Scorpius, not their Uncle Charlie who lived in Romania.

Those letters Rose always waited so eagerly for in the summer were not from a pen pal in Bulgaria.

The mark on Rose's neck two weeks ago probably hadn't been a rash like Rose had claimed.

At first Albus had been too angry to speak to Rose, and so he had studiously avoided her for the next two days because he knew otherwise he might say something to her that he would regret. This time had given him a chance to cool down, and eventually he had decided to seek Rose out and give her a chance to explain why she had felt the need to lie to him. The fact that she had felt she couldn't trust him with her secret was what had really hurt him.

So the next morning Albus had pulled Rose aside with the intention of reconciling with her, and this would have been what would have happened, if it hadn't have been for the fact that when he confronted Rose he found out that the place where Rose and Scorpius had been meeting to carry out their secret affair had been the Room of Requirement.

Out of all of the things Rose could have done this was the worst. The Room of Requirement had been their room. Albus and Rose had discovered the Room of Requirement together in their second year using the Marauder's Map and Albus' invisibility cloak.

For them finding the room had given them their taste of adventure. With Voldemort and his Death Eaters gone Hogwarts had become a very peaceful place, and while Albus was grateful that he never had to fight in a war, or face a basilisk, or live on the run; he had always wished for just a little bit of adventure. The Room of Requirement gave him and Rose that taste of adventure. At Hogwarts the Room of Requirement had taken the place of their old treehouse, only it had been a thousand times better. The Room could become whatever the entrant required. And so the Room had become a great big forest for him and Rose to hike in, a ring for them to duel and practice spells in, and a refuge for them to spend time away from the rest of their family. The Room had given them the sense of adventure and magic that had been lacking even in a magical place like Hogwarts. And part of the magic of the Room was the fact that nobody else knew about it. The Room was supposed to have been his' and Rose's secret place. His' and Rose's.

It wasn't supposed to be Rose's and Scorpius' secret love shack.

"You took Scorpius to the Room?" Albus exploded at Rose.

"I'm sorry. I never planned on telling him about the room, but I had no choice. We needed somewhere where we could meet in secret."

"You know there's been plenty of times I've wanted a secret place to meet with my girlfriends but I've always managed to find somewhere else to snog." Albus said snarkily.

"This is totally different Albus."

"No it isn't. That was supposed to be our secret. Something that only we knew about. Not James. Or Lily. Or Fred. Or Hugo. Or anyone else. Just us. And you took a Malfoy there? That's sacrilege. You might as well have taken a Death Eater to a Harry Potter convention."

Rose's eyes went wide at these words and the next thing Albus knew Rose's hand had reared up and slapped him across the face.

"I can't believe you!" Rose exclaimed, before turning and running off in tears.

Albus was left in shock because he was pretty sure that he was the one who was supposed to be angry and indignant, not Rose. After all he wasn't the one who had lied to his best friend and showed their secret place to a Malfoy.

That evening as Albus lay in bed replaying the scene of his confrontation with Rose over and over again, he finally realized why she had been so angry "You might as well have taken a Death Eater to a Harry Potter convention."

Scorpius was a Malfoy. His father had been a Death Eater. Oh crap. Albus had really screwed this one up.

Now it was Rose's turn to studiously avoid Albus. Albus found that she was even better at avoiding him than he had been at avoiding her. Albus had tried cornering her between classes, sitting next to her in class, sending her notes, sending Lily to talk to her, but all to no avail.

In between classes Rose would run off if he tried to approach her. During classes Rose avoided sitting with him, instead preferring to sit with Scorpius. Rose threw away all the notes that he sent her. Lily was told to "Mind her own bloody business."

Eventually Albus became desperate, and desperate times call for desperate measures.

"You have my copy of Hogwarts: A History?" Rose asked.

Albus nodded, producing the book from his bag.

"Give it back." Rose demanded.

"Not until you hear me out."

Rose narrowed her eyes, but nodded her head.

"First off, I want to say that I don't hate Scorpius Malfoy and I don't think that he is a Death Eater, or believes any of that nonsense. When I said that comment about taking a Death Eater to a Harry Potter convention, I said that because I wanted to express how upset I was that you had taken someone else to our Room. Evidently I need to work on my metaphors though." Albus said, giving Rose a sheepish smile.

Rose looked at him sceptically and then said "If you don't hate Scorpius then why were you so upset when you found out I was dating him?"

"Because you lied to me Rose. You're supposed to be my best friend and best friends don't lie to each other." Albus answered.

Rose looked down in shame and said "It wasn't because I didn't trust you. It was because I was afraid that you would talk me out of it."

Albus looked at Rose in confusion.

"When I first started my relationship with Scorpius I was plagued with doubts because I'm used to being logical and responsible and sensible, and my relationship with Scorpius was none of those things. Nothing about my relationship with Scorpius makes sense. We're from different houses. Our families hate each other. Our personalities are totally different. And half of me knew these things and thought it was never going to work. But the other half told me not to care because what I had with Scorpius was so wonderful. So I went with my heart and ignored all of my doubts, but I knew that if somebody made an appeal to my sensible side I would start to question my decision, and that's why I never told you."

"Do you still have doubts now?" Albus asked.

"I'm in too deep now." Rose answered.

"You look wonderful Rosie." Albus said, after he had slipped into the room where Rose was just finishing getting ready for the wedding.

"Albus!" Rose squeaked in surprise. "Aren't you supposed to be with the other groomsmen? What are you doing in here?"

"I just wanted to make sure that you're doing okay. Don't worry I didn't come here to try and talk you out of the wedding." Albus said, joking.

"You wouldn't be able to even if you tried." Rose replied, grinning at Albus.
