The first time it happened, everyone noticed. A guys first kiss is supposed to be a private affair, but like everything else in a mutants life, what is supposed to be normal is usually not, and what decisions are made are usually the difference between life and death. Leo had seen her before, fought her before, bested her before, hell, even cut her with his katana before, but until today, he had never touched her.

At first, it was like any other battle, the Foot were pressing them hard, an all out war was going on all over the rooftop, his brothers were engaged in various other fights across the cement building while he went for whichever fighter was the most skilled and posed the most threat. Today, like always, that person was Karai.

Leo had always been the one to win the fights in the past, albeit it was not easy, Karai was the only single person aside from Shredder who was a challenge for him. Her style was different from his own, and when they fought they moved so fast and so perfectly and with such precision that his brothers often said it looked like they were dancing.

Tonight was different.

Tonight she got lucky.

Leo didn't see the puddle of blood on the rooftop in time and lost his footing, Karai used this to her advantage without a seconds thought, using his forward momentum to slam him up against the wall and his momentary disorientation to disarm him. Leo realized a split second too late what had happened when he felt Karai's blade at his neck.

That was it. He was dead.

He heard Raph's scream of denial and saw him rushing towards them, apparently during their fight the other Foot soldiers had been killed. But even Rapt knew that they were too far away to help him. He looked back at his attacker and swallowed his disappointment and fear, determined to meet death bravely. Karai was breathing heavily, the gold in her eyes flashed dangerously as she leaned closer, no doubt to gloat about her victory, Leo braced himself for the pain of death that he knew was only seconds away. What he didn't prepare himself for was the feeling of Karai's lips pressed against his.

He heard his brother's gasps and the stunned silence that followed. He saw Karai's face pressed against his, her eyes were closed, she had a scar barely disable beneath her hairline, and a blush was coloring her usually pale skin.

She was actually quite attractive.

Mean as hell judging from past experience, but attractive nonetheless.

Why harder he noticed it before?

All of this went through his mind in a split second. Karai broke away from the kiss before he could really come to grips with what was happening or even start to enjoy it.

Karai flashed him a grin and then she was gone.

Leo was left staring at the spot where she had been standing. Unsure what to think, feel, or do.

Raph was the first to break the stunned silence.

"WHAT THE SHELL WAS THAT?"
