A/N: If you've anything against those who show signs of being gay, you may not like the latter part of this chapter. But being so myself, I stand by the last comment made by Roxas on the matter.
Keep your opinions on it to yourself though - especially the negative ones.

It was agreed that night that Roxas wouldn't go getting him into trouble at night, and in exchange Roxas would have every other day to himself. They'd only break with that if they felt it necessary, or for one to handle something the other couldn't.
As Roxas had been the one around for most of that day, it had also been agreed that today was Sora's day. As usual, Roxas passed comment on his choice in clothes, pointing out he still looked ridiculous. Sora ignored the comments, grabbing a quick breakfast then heading out and down into the tunnels to find Riku.
I had a thought last night once you went to sleep, Roxas said as he made his way there.
What's that?
Well, the twins told us that anyone who got close with either of them would end up like us, right?
Yeah, I remember that. Why bring it up?
Didn't Riku say he had an interest in Kairi too, the day after they got here? Why didn't he get affected by it?
Probably because he never actually met them until after Setzer took them to the mansion.
I think it's possible to get close to someone without meeting them. I mean, look at me and Xion. Until last night, I'd never met her in person either.
If you're really all that curious, I can ask him.
Would you mind? I'd wait until tomorrow, but I'm impatient.
I noticed.
Riku joined him in the tunnels before he reached their usual spot.
"Hayner's asked us to meet him up on Sunset Hill," he told Sora.
"Asked? Are you sure he's not up to something again?"
"Well, if he is, he can't sneak it by both of us, can he?"
"True. Gotta question from Roxas for you."
"He wants to see if my nose breaks the same as Seifer's did?"
"Be nice," Sora murmured. "The twins explained why Roxas exists to you, right?"
"Yeah, you had a crush on one, puts you close to them, so he pops up with a crush on the other."
It's not a crush! Roxas spluttered in the back of his mind. Sora ignored it, smiling. He couldn't hide anything from Riku, he knew Sora too well.
"You told me you had an interest in Kairi the day after they got here, so he was wondering if you'd got hit by it the same as we did."
"Nah. I was just saying that so I could tease you over it."
"Oh really?"
"There's more to it than that, but I'm not telling. The twins know though."
I wonder what he means by that, Roxas mused as they emerged back out into the morning light.
Hayner was waiting alone for them on the top of Sunset Hill, which wasn't like him. Always before he'd have the rest of his gang around – much like Seifer, though at least Seifer wasn't afraid to appear without them.
"Is it just me," Riku murmured to Sora, "Or does he look slightly odd?"
"Looks just the same as usual to me."
He's stood differently, Sora.
Sora passed that on to Riku.
"I thought so. He looks like he's trying to stand like Seifer normally does."
Hey, Roxas? You don't think we got Seifer and Hayner the wrong way around, do you?
I did warn them we might make a mistake, Roxas replied. Maybe that's why he's asked us here.
"What's up Hayner?" Sora called to him. "Riku said you wanted us."
"Did you do this on purpose?" Hayner asked him acidly, gesturing to himself. "Think it's funny, do you?"
"What're you talking about?"
"I'm Seifer, you blockhead! Now Hayner's going around pretending to be me and totally ruining my reputation, and it's your fault!"
Sora glanced to Riku, then whispered in one ear, "Thinking what I'm thinking?"
"Think he'll do it?"
Of course he will, Roxas chipped in, naturally already knowing what Sora was thinking.
"Roxas thinks so, and so do I," Sora answered.
"Let me suggest it to him. He might still be a bit annoyed at finding out about you and Roxas."
"Sure you can handle it?"
Riku winked at him, then they turned back to Seifer.
"We've got a plan," Riku told him. "It'll probably get you back to your old self in no time."
"Probably?" Seifer asked, eyeing Riku suspiciously.
"Hayner's telling everyone he's you, right?"
"I already said that."
"So just do the same. You and Hayner don't get along, everyone knows that. So what better opportunity to do the same thing to him?"
"I don't..." Seifer started, then seemed to take it in, thinking it over. "You might have a point there... he would get a little... bothered by it, wouldn't he?"
"So what do you say?" Sora asked. "Think you're up to pretending to be Hayner for a bit?"
"What am I going to tell Pence and Olette?"
Riku seemed to consider it, then answered, "Might want to keep it from them. Olette, at least. Pence knows what happened, he might understand if you tell him what Hayner's getting up to and why you're doing it."
"And if you're ever at a loss for something to do, you can always come bother us," Sora added. "Or pretend to, anyway. Hayner often shows up just to bug us."
"I'll... give it a try," Seifer said, starting to look a little more like Hayner now he was trying to.
"But don't bother us when we're trying to prank people, will you?" Riku asked. "If you're going to pull it off, you've got to learn to take our side of it. Hayner does, so you've got to."
"I'll pretend not to notice anything you do until I get back to normal," Seifer nodded, then grudgingly added, "Thanks," as he headed past them back down the hill.
"He's even starting to walk like Hayner does," Riku noted.
"There's still something very Seifer-like about him though."
"I think it's because he still takes himself too seriously. He needs to learn to loosen up."
Maybe acting like Hayner will get him to achieve that, Roxas suggested. Sora mentioned it for him, since Riku couldn't hear him.
"We can hope. It'll be nice not to have to worry about him chasing us up after every new trick we pull."
"Are you kidding me? That's half the fun! Remember a few days ago when we got him with that new catapult of yours?"
"How could I forget? You could just picture the paint on him when he came to find us afterwards, even though he'd cleaned it all off him."
They watched Seifer head out of sight, then Riku shook his head, chuckling to himself.
"Something funny?" Sora asked.
"Just thinking about what could happen. Knowing Hayner, he could decided to try to outdo Seifer at this instead."
"I dunno. I reckon he'd come to us to try and convince Seifer to go to the mansion with us to get it sorted."
"Yeah, but think about it, if Seifer starts to get into his role as Hayner, he could decide to do the same thing Hayner is right now. Then what?"
"I guess we give Hayner some advice on how to bug Seifer some more."
"Exactly. They'll keep coming back for more if we do that."
"Sounds like fun," Sora grinned. "Should we find Hayner first, or let him come to us?"
"Nah. Let him come to us. I've got a plan anyway."
"Another one?"
"You know that storeroom that leads to the mansion, right?"
"Of course."
"How about if it belonged to us? We could hide the route to the mansion, have a good reason to persuade people not to come look..." he trailed off.
"And generally do anything we wanted?" he suggested.
"Yeah."
Here we go again, Roxas sighed.
We'll give you a room to yourself if you stop that.
Really? All to myself?
Sure. Why not? Means you don't have to share with me. Well, sort of.

The storeroom had turned out to be unowned, and after Riku paid a visit to the town hall, he'd come back with a broad grin, and apparently with complete permission to do whatever they wanted with the place, provided they funded it themselves.
Most of the day after that had been spent tidying the various junk that was in there so they actually had some space to work with. None of it was thrown away if one of them thought it could be useful for fixing up the place, and even what was being marked to be chucked out was just stored in one room until they had some way of getting rid of it.
Riku had marked one room as behind his almost as soon as they started to gain some space, prompting Roxas to persuade Sora to claim one for him before they ran out of rooms. Riku had agreed surprisingly quickly.
When they made to lock up and leave before it got too late, Hayner – the real Hayner – found them.
"What're you two up to?" he asked, not quite pulling off Seifer. "Causing trouble again?"
"Pull the other one," Riku told him. "Seifer told us what you're up to already."
"Aw, come on! You could at least gimme a chance!"
"Didn't you have enough chances through the day?"
"Yeah, but I didn't find you until now." He paused, then curiously asked, "Did you say Seifer told you?"
"Yeah, why?"
"What's he up to?"
"Trying to be you, last we saw," Sora supplied. "Pretty well, too. I'd say almost better than you're pulling off him."
"Oh yeah? Well I'll show him!"
"You know, I think you might have been right," Sora told Riku. "It could be a long while before they stop trying to get the better of each other."
"Told you so," Riku answered. "Don't suppose I could crash at yours tonight, could I?"
"Huh? Aren't you headed home?"
"I guess I could, but... eh, it's alright if you don't want me to, I guess it is kinda short notice."
"N-no, I didn't mean that, I just... you caught me by surprise. I don't think there's much room for you."
"Hey, I don't mind nicking a bit of floor from you."
"Seriously?" Sora asked sceptically, starting to wonder if Riku really did have another side to him. "You'd rather pass up your own bed for the floor?"
Riku nodded, "If you don't mind me being there, that is."
"Did Kairi put you up to this?" he asked suspiciously.
"When would she have had the chance to do that? You've been around me all day."
"Except when you went down to the town hall," he pointed out.
"True. Didn't run into them though, only Seifer being Hayner pretty well."
If I didn't know better, I'd say we made a mistake with Riku too, Roxas remarked. He's acting very oddly.
You noticed. I don't know what to say to him...
Think he'd notice if I borrowed your voice again?
Why not just have me say it, Roxas?
Because I know you, Sora. It's the kind of thing you'd never say.
I think he might notice then, yeah.
Let me give it a try anyway.
"No offence meant, Riku," Roxas said for him. "But... don't you think if people heard about it, they might think that we're..." he left it hanging at that.
Riku glanced down to him, a smile over his lips.
"What's wrong with that? It doesn't matter what people think, so long as you know what's true, right?"
"I'm the one who's got to live with it though," Roxas answered, still talking through him. Sora had no idea what he was talking about. "And you know what some people are like about that sort of thing."
"Better than you do," Riku answered. "Don't worry. I get it. See you tomorrow."
"No you won't," Sora said, taking his voice back.
"You're right," Riku remembered. "See Roxas tomorrow, and you the day after."
What was that about? Sora silently asked Roxas as Riku veered off to wherever his home was.
You mean you still didn't get it? It was fairly obvious.
You mean he...
I think he might be. Or leans that way. Why else would he say he knew better than us?
I guess... Roxas, you don't think...
Go on, Sora. Just say it.
If he is, you don't think he's got it in for me, do you?
Can't deny some people are like that, Sora. At least you know now that he might, rather than being so oblivious about it.
Sora was left lost for words. He'd never even considered it before.
It was true though. He did know how people in these parts reacted to... things like that.
On the other hand, it did sort of sound just like Riku. He never was one to fit in, he had to be different... and he had taken to Sora fairly quickly...
