...
Roxas knows he's not the most mentally stable of the Nobodies. There are times when his whole body is filled with rage and he can hardly think straight, there are times when he can't control his own mouth, and he says things he doesn't mean to say, things he doesn't even understand.
There are times when he will fight with Axel for no reason other than to release the energy inside him. Usually they fight to a draw. He has hurt Axel countless times, and although Nobodies heal quickly (nothing there to heal) Axel has kept some of the scars on his body. When he sees them Roxas wants to apologize but he never manages to work himself up to it.
Right now Axel is dozing beside him. They don't need to sleep, usually they don't, sleep treads the edge of non-existence. The only reason Axel is sleeping is because he trusts Roxas to watch him and make sure he stays real. He trusts Roxas all the time, even when Roxas is charging him with a keyblade, even when Roxas is being bitter or freaking out.
Roxas stretches out his arm and allows it to melt into Axel's chest, all the way up to the elbow. He wishes he could step into Axel so that they could inhabit the same space in the universe.
If this is how he feels without a heart, real love must be terrifying.
