'Hiashi! You bastard! Give me my body back! You're insane, there's no way my father's in my brain, and even if he was, I'm keeping him in here! You can't have him, he's my father!'
Neji was protesting the theft of his body very vociferously, having lost his reserve about cursing since he was sharing a body with Hiashi. Obviously, he reasoned, there was only so much damage his (currently Hiashi's) body could take and remain mobile. In fact, the situation had made it so that Neji much angrier with his uncle than Neji was scared of him, even though they were stuck together, and Hiashi could seem to hear every thought going through Neji's head.
'You know, he was my twin before he was ever your father. That means that I have dibs, and you'll just have to move aside for your father while he and I have a beautiful reunion.' And there Hiashi went again, babbling about some kind of reunion with Neji's father. Neji didn't want to think about this too hard, or he'd receive some very scarring mental images he didn't need about his father and uncle. And besides, it was doubtlessly all in Hiashi's sick, twisted imagination, made all the worse by the insanity. His father was a paragon of virtue, the embodiment of all things right with the world, and a role model all children should follow!
'Well, that just means that even if he was in my mind, you still had him for 15 more years, so he should stay exactly where he is! With his loving son, who'll take care of him much better than you ever could!' Not that Neji was admitting that his father was, in fact inside of his body. But since Hiashi hadn't listened to his more rational arguments, Neji would just have to try a slightly irrational argument, wouldn't he.
'Hmph, well it just so happens that you don't have a say in the matter. Now, you can shut up like a nice little brain puppet, and ... What? Something's wrong! What's happening?' Shoving Neji's personality as deep into the psyche as he could, Hiashi whirled Neji's body around and broke into a headlong flight toward the room he'd recently left his old body in.
----------------------
Hizashi was satisfied. His brother was dead by his hand. Hah! And that outfit! He'd have blackmail material for all of eternity with that information. And the best part was, the dead were stuck in the outfit they had died in! No more, 'Hizashi, you look totally great in those cat ears, you should wear them more often!' This time, he had gotten the last laugh, both right before his death, and now at Hiashi's death as well. And despite the fact that he was inside of the spawn of that woman Hiashi had chosen over him, its actual mind had been disposed of, and in a moment, Hizashi would leave to find Neji.
Fortuitously however, this was the moment Neji chose to run through the door. And upon seeing the obviously dead (to a Hyuuga) body on the floor, turned on the seemingly hapless Hinata sitting on the floor, and spat, “Hinata! What happened to my body! You useless ditz, you couldn't read a simple 'Keep Out' sign? It was only right on the door! And you couldn't manage to protect it while you were here? Who killed my body, Sasuke-dammit! Answer me, you worthless excuse for a daughter!”
Hizashi turned Hinata's head up to look at Neji's face incredulously. That didn't sound like his precious, innocent son. That sounded remarkably like his no-good, sadistic idiot of a brother! Wait, was that why Hiashi's body had been comatose? Had his brother possessed his only son? What was wrong with him? What was wrong with this world, where a deceased twin couldn't entrust his orphaned son to his brother without the brother taking advantage?
“Hiashi... I'm going to kill you, you bastard! You possessed my son? I trusted you! I thought that you'd take care of him after I died for you! I'm going to beat you senseless, get you out of my son's body, and then I'm going to spend the rest of eternity kicking the crap of you!” As Hizashi-in-Hinata was ranting, he was also frantically poking at Hiashi-in-Neji.
Now, if this had been the two of them fighting in their original bodies, it might have been a bit more one-sided. Hizashi had always been the better fighter of the two, and Hiashi had slowed down a bit as a result of old age. Hinata, on the other hand, had a body very much unlike Hizashi's old body. The chest got in the way, for one thing. Added to that, was the fact that he'd been dead for fourteen years, and Hizashi was at a distinct disadvantage against other living ninjas. But Hiashi had also been transferred to a new body. And despite Neji's advanced skill, Hiashi had been in his original body for 46 years, and unlike Hizashi, was unable to change bodies at will. And so the fight basically consisted of Hizashi poking ineptly, and Hiashi dodging awkwardly.
----------------------
Meanwhile, Hiashi was busy having a revelation. That didn't look like his meek, timid daughter. It actually looked and sounded somewhat like his distorted and fuzzy memories of his dead brother! And is Hizashi was actually in Hinata, that meant that he wasn't in Neji! And so he promptly ejected Neji from their shared body.
Hizashi took advantage of Hiashi's moment of realization to disable Neji's limbs via Gentle Fist poking. Grabbing Neji with both of his hands, he shook Neji's head back and forth, screaming for Hiashi to get out of his son. Hiashi began to cackle maniacally.
“Sorry, brother, Neji isn't here right now. He's vacated the premises, and I'm the only one here. But welcome back, brother!” And that snapping sound was Hizashi's self-control breaking along with Neji's arm. And one of his ribs.
“You... you did what? For the love of Sasuke, why would you think I'm interested in coming back for you? Especially after you've practically killed my son? I'm leaving to find my son, and you are going to stay here, and wait for me to come back to return Neji to his rightful place.” It might have been his imagination, but Hiashi would have sworn that he could hear Hizashi mutter under his breath, “bitch.”
With that parting shot, Hizashi-in-Hinata ran out of the room, leaving his incapacitated brother-in-his-son's-body lying on the floor next to said brother's dead corpse. Hiashi was heartbroken.
----------------------
Neji was horrified. His uncle, who was currently possessing his body, had gotten his rear end handed to him by Hinata! Since he'd been deeply submerged in his own psyche right before he'd gotten ejected, Neji wasn't sure what she'd been screaming about, but when he got his body back, he'd teach her not to break his arm! That was going to hurt when he got back in it.
Now, how to re-enter his body? Wait, how was he going to move?
