For the record, I'm not quite sure whether or not Roxas knew about Sora or his connection to him in the scene that was the base for this fic, but I'm just going to assume that yes, Roxas knew about him and yes, Roxas knew what he was. If I'm incorrect, you may inform me POLITELY of my error, and I'll use it for future reference, though this fic probably won't be changed.

"Why... why do you have the Keyblade?" The pain in Riku's voice was unmistakeable, but for the life of him, Roxas could not see where it was coming from. Surely... Riku wasn't jealous? Not when he was just as capable as the blonde of wielding the Keyblade and had one of his own. There was no reason for him to be upset about there being more than one Keyblade master, not when there already... and at the thought of the third wielder, it became clearer.

Riku's question wasn't, 'why do you have the Keyblade', it was, 'why do you have Sora's Keyblade.'

"Shut up." Because he is me and I am him, and I have more right than anyone else. More right than you, you're a horrible excuse for a best friend.

"What did you say?"

Roxas had spoken the last part out loud.

No use denying it- Riku had heard him, and was clearly angry. Blue eyes- or were they green?- glared furiously up at him from behind silver strands of wet hair and a black hood.

"You... you left your best friend alone so you could have bonding time with the darkness! Do you know how painful that was for him?" So painful, I could feel it still when I was created, long after it had happened.

The anger in those curiously coloured eyes backed down some, and gave way to guilt.

"I... had to. Kairi... she needed my help..."

"So you chose Kairi over Sora? Then I guess you have no say in what I am to him-"

"That's not true!" Riku leaped back to his feet and took an aggressive stance. Roxas could tell he was somewhat shocked that the Nobody had figured his feelings out, but Riku didn't let it phase him. "Kairi needed me more than Sora at the time- I can't just choose between my two best friends like that-"

"Two best friends? Oh no no no, Riku, human beings are only allowed one true best friend in this world. You can't split your heart into more than two pieces... but, oh dear, it seems Sora is already sharing his with someone else, isn't he?"

Riku faltered for a moment, eyes downcast. Roxas smirked- even he himself would be hard pressed to come up with a better argument.

"You're... wrong." Roxas tensed once more, looking directly into those lovely green-blue-green eyes. "Maybe your... 'heart' isn't big enough to give to more than one person, but mine is, and Sora..."

Riku didn't need to finish that sentence. Sora's heart was big enough to share with the world and then some, even with half of it gone. Roxas had to admit, maybe this guy really was Sora's best friend, he knew and loved him well enough.

"Then... I guess... we'll just have to share."

Riku's face jerked into an almost comical expression, eyes wide, mouth flopping open. Then, he almost instantly calmed down. "Are you sure you can handle that?"

Sora's other half smiled, for once, at Sora's best friend, and said that maybe it wouldn't be as hard as he thought.

I realize this may look like I've had Riku choose Sora over Kairi (friend wise) but that's not what's intended. Please be open minded and understand that's just how it came out.
