Run for it.

Ichigo said, "Fine, fine, FINE!"
"You'll do it then?" Renji asked.
"Yeah. I don't have much of a choice do I?" He looked balefully at Byakuya who stared just as balefully back at him.
"I'll take you over there," Renji offered.
"Never mind! I'd rather go myself. I know where it is."
Byakuya said, "Good, because Renji, I have something else I need you to take care of."
"Right Captain. Later Ichigo," then Renji turned to his captain and both walked away from Ichigo.
Ichigo made it look like he was going in the direction of the 12th Division Captain Kurotsuchi's research center, but as soon as he was out of sight of Renji and Byakuya; he made a break for it. He thought, "There is no way in HELL I'm going to meet with that freak show of a captain. He'll probably put me through all kinds of strange experiments that I bet would be incredibly painful. Nope. Not gonna do it. Gotta find a captain, a lieutenant, or someone friendly to show me the way back home again."
He ran through the streets, trying to stay close to the sides of buildings, creeping around corners, and ducking into shadows. Everywhere he looked, he couldn't find someone of the proper status, no captains, no lieutenants, nor anyone friendly to help him.
Then to his utter horror, as he rounded a corner near a sparsely populated area, he ran into a captain, AND a lieutenant, one of which was friendly, while the other was anything but.
"Oh no. This can't be happening," Ichigo thought as the captain in front of him spied him. He kicked furiously at the dirt. Then he put his hands on his hips and waited, while the captain in front of him broke into a wide toothy grin.
"Well, well, well. Look who we have here."
"Oh no," Ichigo thought again, as he felt the gravity in the area change as the spiritual pressure burst forth from the captain in front of him as if it was searching his own out.
He stammered, "Listen. I don't want any trouble. I'm just trying to get away from becoming a test monkey for that Kurotsuchi freak and get back home!"
The captain said, "Kurotsuchi huh? He is a freak. He wants to make you a test subject today does he? Interesting, but not my style." Another wave of energy flowed from the captain – Ichigo felt it press hard against his chest. The captain took a step forward and said, "I've been waiting for another shot at taking you down Kurosaki. Come on. You game? Wanna go another round? If you live, I might show you how to get home."
Suddenly, the lieutenant standing beside the captain jumped up and down, and yelled with glee, "YAY! Ichi and Kenny are going to fight again!"
"WAIT! I never agreed to anything!"
Kenpachi reached forward before Ichigo could run away. He grabbed the substitute soul reaper by his robes and began dragging him away from the city. "No! I don't want to fight you now! Some other time, but not now! I'm not prepared!"
"Uh-oh," Yachiru said as she stopped walking, "You're making Kenny mad Ichi."
Kenpachi turned on Ichigo and growled into his face, "A shinigami is ALWAYS prepared for any fight he finds himself in. And if you've forgotten that maybe I need to beat it back into you, or cut the hesitation to fight out of your heart."
"That's it Kenny! You tell him!" the little pink haired girl chanted.
Ichigo really didn't want a full out battle with Kenpachi then, because he knew that he'd have to be put back together again if he won OR lost this time. But something inside him did stir, the tiny fire that made him WANT to fight, WANT to win. Kenpachi's eyes started to widen with anticipation and the lust for battle, because he could feel that fire growing in Ichigo too.
"That's better. Now come on. Let's get outside the city so we don't knock any buildings down. They don't like it when I do that."
"YAY! This the best day ever Kenny!" Yachiru said as she ran off ahead of them.
. . .
Fourteen hours later, Ichigo lay panting in the dirt. He was covered in slashes; he'd lost a lot of blood. Kenpachi was equally scored, and was impressed again with Ichigo's growth. In fact, he was relishing their fight again so much, that he wanted to stop it so they could continue again when they were fully refreshed and healed. He stomped over to Ichigo and bent over him, his maniacal eyes staring into Ichigo's. He picked him up by the front of his tattered robes and said, "That's enough for today. I had a lot of fun. Get better, get back here, and we'll fight again." Then he put Ichigo back down on the ground and began to walk away.
Yachiru said, "That was nice of you not to kill Ichi, Kenny. I like him. You have a lot of fun when you fight with him."
Then Ichigo stirred and got up on his elbow. Kenpachi must have knocked something loose in his head, because what he said next, defied all laws of common sense, "So Kenpachi, you quitting because you're afraid you were going to lose to me?" He half smiled, half scowled at the enormous blood streaked Captain.
"Uh-oh," Yachiru said as she stepped away from Kenpachi. "Nice knowing you Ichi."
Kenpachi looked over his shoulder at the still prone substitute soul reaper. Instantly Ichigo knew he'd said the wrong thing.
A sudden violent pulse of spiritual energy burst forth, just as Kenpachi's ragged zanpakuto slashed backward toward Ichigo. And that was the very last thing Ichigo saw, other than the blood spray from his own chest.
A/N: Never, NEVER EVER be a smart-ass with Kenny! Game over, violently, for you! Go back to the beginning and try a few different decisions.
