Disclamer: I don't own the sand sibs or anything from Naruto.
This would probably best take place pre-chunin exams.
Kankuro passed emotional training with flying colors. He has come to terms with killing on missions and is able to do so with little or no remorse. He is prepared to deal with the loss of his fellow ninjas. He has even accepted the fact that he has a high chance of dying during a mission. But this, this he is not prepared for. This he cannot deal with. And so he doesn't, he refuses to deal.
He tries to understand what happened- to play it again mentally till it makes sense. But his mind cannot fully register it so the replay comes out distorted, a mess of colors and sounds. First there was silence. It came with the green, the cold green eyes that told him he had made a fatal mistake. The eyes spelled it out, his fate was right there in front of him. Suddenly from nowhere came a flash of pink and her pleading voice, then yellow and red.
He lies there in the fetal position in the middle of the now deserted market, completely stunned. He is covered in blood, guts, and grey matter. But he has no desire to clean it off. It makes him feel safe in a sick way. She was protecting him and now she forms his armor. If he could have his way, he would never take it off. He wants to stay this way forever covered in her. Because now she's with him. Now she's closer than she's ever been before. He thought they were close before but now there is no space between them; there is no one but them. The thought brings a kind of grim smile to his face. It has a sort of irony that's so bitter tasting he savors it.
Eventually they pick him up off the street. Eventually someone escorts him, not home, but to some sort of safe house. They put him in a shower, so he can clean off. But he doesn't want to so he stands there, with the water running. The water washes some blood free from his hair. He watches as it goes down the drain. A familiar voice from the back of his memory scolds him, like she's scolded him time and time again for wasting water. And suddenly it hits him like one her of punches. He falls to his knees sobbing so hard he can barely breathe. He sits there in the still running shower, his tears mixing with blood and water, while he watches his sister disappear from his life as her blood is washed down the drain.
AN: I'm not exactly sure where this came from. I just had this image in my head of Kankuro completely traumatized covered in what remains of Temari (her blood, guts etcetera) and I wanted to write a scene to go with this image so I attempted this little drabble. At first it didn't come out very well but the more I reread and tweaked it the better it got. I think there might be some sandcest here if you read between the lines.
Normally I love fluffy, family bonding sand sib stuff but I guess my inner muse is kind of depressed at the moment.
