Raphael's eyes fell open in shock as the heart monitor went flat, and he was up in less than a second, at his brother's side. "Mikey!"

Leo's head whipped around to the door. "DON!"

Donatello jumped as he heard his name yelled in a panicked tone, nearly dropping what he had in his hand. He set the vial down and hurried towards the room, panic starting to take hold of his heart. He really hoped that it wasn't what he feared. He had to have more time than this!

The door flew open as he rushed in, and what he saw nearly made his own heart stop. Leo and Raph were over their brother, trying to get him breathing again.

He grabbed on to Mikey's arms, feeling for a pulse on his wrist, dread setting in his heart when he found none. This couldn't be…

He didn't have the tools to bring him back. Don brought both hands up into a fist and beat them on Mikey's chest, knowing that their plastrons protected them from the harshest of the blows. He glanced at the heart monitor, seeing the little blips that would come across, only to go dead again.

He felt tears dripping down his cheeks as he tried one last time.

Beeeeeeeep…

The sound didn't stop, and Don fell heartbroken into the chair, his eyes wide and staring. He'd been so close to finding a cure… why had this had to happen? Mikey couldn't be dead. He'd failed…

He didn't even notice as a hand was replaced on each shoulder.

Beeeeep…. Beeeep…beep… beep

Don's head shot up as the sound regulated back into the reassuring sound of a heartbeat. He stood up quickly, knocking the chair back as he rushed to Mikey's side.

Leo and Raph looked at each other, not mentioning that both of them had tears in their eyes that they refused to let fall. They both made their way to Don's side and looked at their youngest brother. Their youngest Ialive/I brother.

"You did it Don…" Leo could hear his own relief in his voice.

Raphael's hand snaked forward, grasping Mikey's wrist. He couldn't believe that he'd nearly lost him. His little prankster. His little brother.

Donatello turned his wet eyes up to his eldest brother and hugged him. "I thought we'd lost him…"

He held back his shaking. He had to get back to work on the cure as quickly as possible. He didn't want another near heart attack. He didn't think… no, he knew he couldn't handle it if it happened again.

"We know you can do it Donnie… we trust you. Mikey trusts you. When you've figured this out, I promise, we'll go after Bishop." Leo whispered, comforting his younger brother. "We'll go as a team, all four of us."

Don let a small smile cross his face and nodded. "Right."

He pulled away from the hug and glanced over at Raph who hadn't let go of Mikey's wrist. "I'll do it Raph."

Raphael glanced over his shoulder and gave Don a slight smirk. "I know ya will bud."

Donatello nodded before making his way out of the room. "Call me if anything else changes." He pulled open the door and walked out, the door swinging shut behind him.

As he made his way back to his lab, his mind flashed back to the way his brother had looked, the way he'd felt when he thought he'd lost him. He didn't want to go through that again, ever. He'd make sure that they wouldn't have to go through this.

He pulled open his lab door and quickly set back to work on figuring out exactly how he'd make a cure. He was close, he could feel it.

"How far along has it progressed?" Bishop walked into a middle sized room and over towards the computers where two men dressed in black suits sat.

The one on the right looked up at the one who approached them. "It's already passed into phase two sir. Phase three could take a few more days to complete."

Bishop's eyes narrowed. "I don't want it done in a few days, I want it done in a few hours. Make it happen."

"B-but sir! That's impossible without killing the subject!" The other one had whipped around, looking at Bishop in shock.

"I don't care. We're so close, I want it done soon." Bishop narrowed his eyes further. "Are you questioning me?"

"Never! Phase three will be completed in a few hours!" He turned around and quickly got back to work.

"That's what I thought." Bishop nodded before he turned and walked out of the room. Once he was out of sight, the first one who had spoken turned to the one beside him. "We can't get this done in a few hours. Are you crazy?"

"Don't worry, Bishop doesn't know that. We can pretend." He grinned slightly as he continued to type.

The other one nodded and got back to work as well.

Raphael watched his youngest brother as he lay on the bed, making sure that his chest continued to rise and fall. As long as that kept up, he could be sure in the knowledge that his little brother was alive and breathing.

"You know Don's going to do it." Leo stated, sitting in the other chair.

Raph glanced over at Leo, snorting slightly. "I know dat Leo, ya don' need ta tell me." His words had no bite, but he spoke them if only to keep routine, normalcy.

Mikey was going to wake up, and they'd all be back to normal again, hopefully soon. Raph didn't want it any other way.

Donatello's eyes widened at what he spotted in one of the cells. This could explain why Mikey was in so much pain as well.

He pulled the sample out from under his microscope and made his way over to his computer, running some diagnostics. He and his brothers had been witness to these things before, but never like this.

Nanobots. This most likely meant that Mikey was internally being monitored as well. He frowned at the thought, even if it brought some insight as to what may have happened. He could create a small electric pulse which could destroy them all, hopefully wrecking Bishop's plans.

Right now though, clearing his brother's blood of those harmful chemicals was more important.

His eyes widened slightly as he thought of something. He could kill two birds with one stone. It was possible, if he worked at it hard enough, and, if he had some help.

Don picked up his shell cell, calling a familiar number.

It rung a few times, and then a familiar voice picked up. "Hello?"

"April? I need your help." Don spoke, a little nervous. He really hoped she'd be able to help him with this. It could be the only way to save Mikey.

"Sure Don, what is it?"

"Can you come over, and bring your computer?" He smiled as he heard the affirmative, and then hung up once April said she'd be over as soon as she could.

They'd find it, and they'd cure his youngest brother. There was no way he was going to fail.

"Just hang on Mike, we're close."

I found this chapter on my hard drive... think I wrote it a couple months ago. :P
