"Katie, I'm leaving."

Fred had decided that it was best just to tell Katie straight out that he and George were leaving Hogwarts. He had also purchased a huge bar of her favourite Muggle chocolate.

She gaped at him. "What? Why?"

"Because we don't need NEWTs. Because we can't stand another minute living under Umbridge. Because there's nothing worth staying here, except for you." He said bluntly.

"And clearly I'm not worth that much."

Fred handed the chocolate over.

"Come on Kate, it's a chance for us to get back at Umbridge, as well as finally getting started on the joke shop-"

"It's, like, three months until school year ends though! Can't you wait?" she pleaded.

He shook his head firmly.

"You can't go!" she snapped "I won't let you!"

Fred raised his eyebrows "You won't let me? Look, Katie, I know this has been a shock, but a few months ago I thought I was going to be a dad, and it just made me realise that I've outgrown Hogwarts."

"Is that what started this off?"

"Yeah." He said honestly "And then after Umbridge found out about the DA- well there's nothing here for me and George. We don't belong here anymore. We belong out there."

"You belong 'out there'?" she sneered "Well, good luck with that. Let me know how it works out."

"Katie-" He grabbed her hand "I know you're mad, and you don't want me to leave, but George and I are going and nothing you do is going to stop that!"

He dropped her hand and marched off. He had expected a violent outburst- it was Katie after all- but he had also been hoping that she would be more supportive. He made his way moodily down to the lake, reflecting on her reaction and wondering how Alicia had reacted.

He reached there and threw himself on the ground, gazing out over the water, remembering the time when he and Katie had swam in it. They'd been diving down and he'd got his foot stuck under a rock. Katie had set him free. She helped him. She always did. She was moody and irresponsible a lot of the time but he still needed her.

"Fred?"

He turned his head, and Katie was there, looking apprehensive. "Can I sit down?" she asked.

"If you really want. It's a free country. You can do what you like." He couldn't resist adding under his breath "Apparently."

"Oh, god, Fred, I'm sorry about before." Katie burst out, dropping to the ground. "It was really unfair of me, you've been planning this since you were about five and I should have been supportive, and it's not like you're going to be here next year anyway. I need to get used to it..." she paused to take a deep breath.

"Do you mean that?" asked Fred "Or are you just trying to be nice?"

Katie looked offended "Yes, I bloody well mean that! When do I ever bother to pretend to be nice?"

"Good point." They looked at each other for a split second, and then relaxed.

"I just saw Alicia and George." Katie offered. "Alicia was crying and George was just being useless."

Fred smiled. "He always was the more useless of us."

Katie raised her eyebrows "I don't know. He managed to ask Alicia out quite successfully- better than you asked me. In fact, you didn't even ask me."

"Katie, shut up." He grinned and leaned in to kiss her.

"So-" said Umbridge. "You think it amusing to turn a school corridor into a swamp, do you?"

"Pretty amusing, yeah." Fred was looking up at Umbridge, but his eyes slid across to Katie, who stumbled as she was eagerly pushed to the side by Filch, who handed Umbridge a piece of parchment.

"You two," Umbridge said with sadistic glee "are about to learn what happens to wrong doers in my school."

Fred caught Katie's eye. She winked. It was like a signal to him, and he turned to George "You know what? I don't think we are. George, I think we've outgrown full-time education."

"Yeah, I've been feeling that way myself."

Katie readied her wand. She could see a member of the inquisitorial squad prepared to start forward, and he was close enough to grab Fred.

There was a spectacular crash, and she ducked as the brooms flew over her head, skidding to an abrupt halt in front of the twins.

"We won't be seeing you."

"Yeah, don't bother keeping in touch."

The twins could hardly keep the grins off their faces as they mounted their brooms and prepared to kick off.

"Of anyone fancies buying a portable swamp, as demonstrated upstairs, come to 93, Diagon Alley- Weasley's Wizard Wheezes, our new premises!"

Katie pointed her wand at the hulking boy who was going to grab Fred. Any second now, they were going to make their triumphant exit, and no one was going to ruin it for them. She knew that Angelina, Lee and Alicia, all in different places in the crowd would also be ready to jinx, hex or curse anyone who tried to stop the twins leaving- even though Fred and George had forbidden them too arguing that it would get them into pointless trouble.

"Special discounts to Hogwarts students who swear they're going to use our products to get rid of this old bat." George grinned.

"STOP THEM!"

As Umbridge screamed, Katie whispered "Impedimentia!" The boy was slowed right down and the twins shot up into the air. As they flew off she blew Fred a kiss, and joined in with the cheers, pointing her wand into the air and sending out sparks, even though she knew she'd get into trouble for it later. It was the twins' greatest moment in a seven year career. Even Alicia was whooping.
