Well, this one's not 100 words, but it meets cupcakemonster's criteria of "platonic" better. :)
Title: One-eyed Meanie
Game/ Characters: FFX Auron, Rikku
Auron arched an eyebrow at the word more than the small fists planted against his chest that he barely felt through armor. Jecht had used rather stronger language to mock him.
He pondered picking Rikku up by the scruff of the neck, but she didn't quite have a scruff, and anyway, her tiny body, a boiling mass of indignation and wirey strength, didn't deserve that sort of indignity. So he shrugged. "I felt the same way."
Rikku was too busy shoving him against the cavern wall where he was allowing her to shove him to notice. The dour Guardian checked to make certain Yuna was still dozing before he continued. "In the end, I asked Braska to turn back."
"Wha?" Rikku backed off, mouth puckering in an 'O'. "So why'd you keep push-push-pushing Yunie to come? Why?" Her eyes teared up. "You know what's gonna happen! You've seen it!"
The grey haired man didn't rage or gnash his teeth or howl protests; all they had garnered him was a cold, hard landing on a marble floor with Yunalesca's gloating ringing in his head. He simply nodded, expression brittle. "I... saw."
"See? So we can't let that happen again!" Rikku seized the edges of his coat and tugged emphatically, spotting a sudden opening, an ally where an enemy had been a moment before.
But that was all the answer Auron could give. They had to see Yunalesca for themselves. He couldn't repeat that bitch's mealy-mouthed lies to them. They had to see, and understand, and know. And maybe, just maybe, Jecht's son would be angry enough against Sin and Spira and doing things the right way -- Auron's way, his father's way -- to think of something else.
He shook his head. "Because it's her story."
Rikku spluttered, but "meanie" was sadly inadequate for the names she wanted to call him. Maybe Tidus could help her work up an adequate epithet, in between figuring out how to save Yunie and the planet.
