A/N: So...I know I'm a terrible person. I had the rough version of this down a month ago, but I finally got it typed up for my Beta to look it over a few days ago. Anyone waiting to get answers? Well, here are those answers! No more secrets here! I love writing lines for Bishop . It's really thought-provoking. Anyway, I won't hold you up any longer. Happy reading!

Bishop could hardly contain his distaste. The trial run was successful, sure, but the outright refusal to follow the plan only reinforced his desire to replace Stockman. The massacre at the Bank of Manhattan could have gone wrong in too many ways. He reviewed the footage before him from three different angles. One of the angles was from the eyes of the culprit himself. The amount of carnage was unfeasible. Therein lay the flaw in Stockman's reckless act. Death so vile always gathered the most media attention.

There was a groan behind him. Bishop remained stoic. He knew exactly what it meant. There was one benefit to the night's events. That benefit was currently contained into the examining table in the middle of the room. He turned the volume up on two of the security tapes before him for his guest. At the very least, he could make use of the failings of his subordinate.

He could see the captive's reflection in the glass-finished walls. He watched the initial struggle before the turtle stilled. He was watching the videos as well now. Only then did Bishop address him. "It's messy business, what you see before you, but what Stockman lacks in tact…"

He watched Leonardo's fists clench as one video froze on the clear image of the perpetrator's ungloved hand. Bishop knew there would be no doubt in his prisoner's mind just who the hand belonged to.

He turned to face his captive. Leonardo's skin was covered in burns. Bishop knew he had to be in pain. The leather bindings were taut against his skin. His men had not been gentle when they prepared him for this meeting. "I find it very intriguing to see the passive turtle committing such devastation. Don't you?" Bishop slowly approached his furious prisoner.

"You'll regret that." Leonardo's voice was low and gravely. "You'll regret every minute you've forced my brother to do your dirty work." He tugged against his binds, uncaring about further pain.

"Including bringing you here?" Bishop asked. "Not to mention what he did to Raphael. How is now, by the way? Do you think Michelangelo can keep him alive without you?"

"If Raph dies, you're dead." Leo turned away from his captor. "Don will break free from your mind game. You can't keep playing him like a damn puppet."

"I can and I will." Agent Bishop moved around Leonardo to a metal table just out of sight. A computer system was set up for him there that controlled the three monitors. "What you are unaware of, Leonardo, is the finality of the procedure done on your brother's brain. With only a few clicks of my remote system, I can cut his mind off from his body. Permanently".

"How?" Leonardo asked, his voice laced in fury. "What you are talking about is science fiction. It's not even possible! What stops me from just breaking your little toy?"

"I wouldn't recommend it." Bishop tapped a few keys on the computerized command system. Two of the monitors before Leo changed what they were showing. Only the one through Don's eyes remained as it was. "This is what is inside your brother." One image showed a series of figures flashing across the screen. The other showed an x-ray image of the back of Donatello's neck. The image clearly showed something that should not have been there. It looked like a mechanical insect attached to Don's brainstem.

"It's fully integrated into Donatello's system. If you attempt to remove it, you'll risk paralyzing him for the rest of his life. That is if he survives the procedure at all. Considering your limited access to medical supplies, he will have no hope of survival. My device has full control of his bodily functions as well. I can induce a heart attack easily. It's part of the failsafe."

Leonardo jerked the table slightly in his rage.

Bishop caught the stifled cry from the action as he returned to Leo's side. "If you don't calm down, you might cause yourself further injury. We wouldn't want that. You might miss out on the dissection I plan to have Donatello perform."

"He's not your puppet! You will not use him as one!"

"I don't have to use him, as you say." Bishop adjusted his dark glasses to hide the glee in his eyes. "There is another entity at play. An AI that has some will of its own. That is what will dissect you. The AI program already claimed its first victim. No carbon based life form ordered Donatello to take Raphael's life. That was only the result of the computer's programming as it fed on your brother's own mental processes. You can consider it like Dissociative Identity Disorder. It works much the same way."

Leonardo refused to respond. There was nothing more he could say and Bishop knew it. He had won. Donatello was fully and completely his to control. Bishop had thought of everything.

The dark underground tunnels blurred before him as Donatello followed a familiar route. He felt physically ill with remorse from an event he couldn't even remember in its entirety. It didn't matter how much he could recall. He knew enough to feel regret.

"Leatherhead…?" He called even before crossed the threshold of the caved in lair. The devastation was suffocating. His breathing caught as slumped to his knees. "LH…" He fisted the ground before him. Why am I not strong enough? I'm a ninja, a genius, and I can't fight off one damn voice in my head?!

He could still hear the bricks shifting and the echoing clatter of cement chips sprinkling the floor. A familiar whirling barely broke through his thoughts.

But I'm not just any voice, Donny. I'm you.

"No." Donatello defiantly shook his head. His hands tightened around the fragmented stone. He couldn't stand for some bodiless thought. He desperately wished it away.

You can't deny what is proven fact.

His hand brushed against his own neck. His eyes widened and he jumped back with a cry. "No, stop it!" he yelled at his betraying hand. "Get out of my head!" One hand moved to cover his ears, but the other remained in place. His arm was out of his control.

"Donny!"

Donatello jerked back at the close proximity of the voice. "…Mikey?" He found his brother with his eyes and quickly put more distance between them. "Stay over there!"

"Where's Leo?" Mikey frowned from where he stood some twenty feet away. His twin nunchucku hung limply in his hands. Don knew the stance well. Mikey was tense, but unsure. He knew something. Why else would he be here?

"Why are you here?" Donatello asked to confirm his suspicions, ignoring his brother's question. Don's stance remained defensive. The cloud hanging over his mind was bidding its time and he knew it.

"You installed an alarm to alert us if anything happened to LH's lab. Remember?" Michelangelo looked confused. His gaze never strayed from Don.

"Oh, yeah…" How could I forget that?! Don shifted in his frustration.

"Leo was here an hour and a half ago. I know because he was on the phone with me, then, to tell me he tracked you down." Mikey slowly stepped forward. "Where is Leo?"

Yes, where is he, Don? Do you remember?

"Stop!" Donatello held his head with one hand as the other shot out to stop his brother's advance.

Mikey froze. His fingers played against his favored weapons. "Donny…do you know what happened here?"

Do you? I can do this all day, you know. How about we just…forget what's not important.

The pain in his head tripled in intensity all at once. Donatello screamed out as his knees once again hit the ground.

"Donny?"

We can make it stop. You know we can.

He couldn't silence the voice in his head. It was only growing louder. Taunting him. Pounding into his thoughts and scattering them into pieces. If only he could just stop thinking! "Get out of my head!"

The voice just laughed. It knew what it was doing to him.

A touch to his shoulder brought him springing into action. His hand snapped forward and pulled. The elbow of his other hand drove into the back of the neck. All he could hear was the disembodied being mocking him in his own voice. If only he could kill that voice!

"Donny! Don, stop!"

His vision cleared at his brother's voice. He immediately backed away in horror. There was Michelangelo. On the ground. Gasping. Where he had just moments before been attempting to kill the voice.

"I…" Don began, but he couldn't form a clear thought. What's wrong with me? He felt so very powerless in that moment.

Nothing's wrong with us, Don. We are what we were always meant to be. We'll do many great things together.

"You did do something to Leo…didn't you?" Mikey stumbled to his feet, rubbing his now sore neck. "Just like you hurt Raph. And LH… Why? What's making you do all this?"

"Just go home, Mikey," Donatello sighed in defeat, "Before something else happens. I can't control this…" He glanced down at his open palm.

We can snap his neck so easily. You know we can. We've done it before.

Don cringed at the thought and dropped his hand to his side.

"Answer my questions! I need to know!"

Or maybe we should just smash his head in. We can really see how much of a brain he has. What do you think, Donny?

"No!" Don yelled as his hands rejoined the sides of his head. His eyes found his brother's. "I don't want to hurt you, Mikey. I don't-"

Do you really think covering your ears will shut me out?

"-But you have to get out of here!" Don's voice rose over the volume in his own head.

We're one, Donny.

"I don't know how long I can stay in control."

You can't block me out, Don. You can't stop me from doing what we want.

"Mikey…" Donatello could feel his control shift. The feeling was so alien to him. He felt the muscles in his arm move no matter how much he wanted to be still. His voice quickened. "Leo…" The memory was broken into pieces, but it was paramount that he tell Mikey as the name came to him. "Bishop. Free him, Mikey. Please…"

It's a real shame he'll only get to see Leo again as a guest. Isn't it, Donny? But don't worry. I won't hurt him much. That's not what we want.

The last of Don's conscious thoughts were filled with the horror that the voice would get its way…
