Even if he had a feeling it would happen, that didn't make the fall any less surprising. He reached out his hands to the floor, trying to stop, cushion or whatever it would help in his fall. In the end there was a thud and just a Sora on the floor, unmoving. The plight to get up would come later. For now he was just staring at him over his shoulder in a blank matter what soon turned fairly annoyed.
With a sigh he uses his hands to turn himself over and push himself up to at least sitting. This wasn't nearly as easy as it sounds. One could imagine what a struggling gimp looked like and he wasn't accepting any help either. Looking back behind him, he reached for his hat, but it was just too far from him. Thus the messy haired man just looked up at him from his place on the floor.
