Demyx was sitting on the couch in the lounge, looking pretty sad. Xire and Roxas came into the room.
"Don't ask..." whispered Xire to Sora, but he had already wandered over. "What's wrong Demyx? You and Mixa have a fight?"
He sighed. "No, its that..." he quickly stopped and looked around. "That lovely person named Larxene!" he said a little too loudly. He bent over low and whispered, "You never know when she might be watching!"
Xire rolled her eyes. "You know, maybe she wouldn't give you such a hard time if you weren't so lazy."
"It's not just that!" said Demyx. "She just hates me..."
Sora sighed sympathetically. "Gee, I know what its like...to have a certain someone you just can't get along with for some reason..." he said, casting a sideways glance at Xire. Her eye twitched and she grinned wickedly.
"You can say that again! Someone who's stupid, rash, and somehow too easy-going...I don't go to well with that kind of person at all..."
Sora frowned and turned. "Xire, who exactly are you talking about?"
"Oh, I don't think you want to know...tee hee..."
By this time, Mixanko, Toxkoma, Axel, and Xion had come by as well, watching the argument with a weird sort of amusement.
"You know, Xire, there's something I've always wanted to say to you..."
"Oh, what a coincidence! I've always had something I wanted to say to you too!"
Xion sighed. "Those two are at it again..."
"Well," said Toxkoma, "They say that arguing can be a sign of good terms..."
"That's not true!" they both said in unison. They then both glared at each other. Sora stuck his tongue out at her. Xire, being older and more mature, repeated the gesture back at him. They both pressed their faces together, still sticking their tongues out furiously.
"Hey now," said Axel, "how about the two of my favorite people settle down and..."
"Two of your favorite people?" said Xire angrily.
"You shouldn't even be included in the list!" said Sora back at her. He turned to Axel. "Why did you ever even bring her to the tower?" asked Sora angrily. "That was supposed to be our thing! You, me, and Xion!"
"Oh, what, are you the only one allowed to bring in new people? You brought in Xion!"
"HEY!" barked Saix, stopping everyone. "You all have missions to do. I suggest you move it."
Everyone walked off, Sora and Xire still glaring at each other.
A little side story I made. It was slightly spontaneous, but I did want to expand a bit on Sora's life in the organization and his relationship with others...and after the scene between them at Kingdom Hearts, they're pretty much bffs, so this wouldn't fit being afterwards. So, just to clarify, this is very shortly after Sora joined.
Something about the words Sora and Xire exchange seem oddly familiar... ;)
