A/N: Please read and review?

As there's hardly any action, this is a short one.


The Turtle Copter flies above the Nevada desert, on a moonlit night.

Leatherhead: As we fly through the night, I can't help but ponder: intelligence, reason, even simple thought.

Onboard, Leatherhead stares at the mutated Donnie, who was banging on the containment unit he was trapped in.

Most people take these things for granted. I do not. For I know what it's like to be an advanced mind, trapped in the body of a brute... of a monster.

Cath comes over to him, as they both work on a panel.

But for once, I am not the monster in question.

Splinter, Mikey and Elisa all sat staring at them, as Leo and Raph pilot the Turtle Copter. They both turn, as Splinter sighs, as the girls both weep slightly.

My friend Donatello is one of the gentlest souls I've ever met, with one of the finest minds I've ever known.

Donnie begins scratching at the containment unit.

But now, thanks to the evil agent Bishop, my friend has been transformed into a thoughtless savage.

Leatherhead and Cath turn to Donnie, who roars.

And I fear that the Donatello I know may truly be lost forever.


In Bishop's base at Area 51, guard towers shine lights down all over the base.

Inside, Bishop was in the lab Stockman had been brought back to life from, staring at a sphere container with water, which had Todd the workman in.

"This is unacceptable." he said. "Your progress on the Outbreak cure is lacking, Dr.. The situation in the city is getting worse, and it's keeping my attention away from my work."

Stockman stood on the other side of the lab near a table.

"Your work?!" he exclaimed, picking up a test tube and a vial. "Please! The original Outbreak..."

He put both objects down on the table.

"...virus was an unintended side effect of the genetic accelerants I created for you!" he exclaimed, turning to Bishop, who stared at him. "There are too many variables. I'm testing dozens of retroviruses."

A beeping noise came up, then a square hologram popped up, showing a soldier.

"Sir, pardon the interruption." he said, as Bishop moved closer to the hologram. "There's a transmission coming in. We can't trace the signal, it's-"

"What kind of signal?" Bishop asked.

"We've never seen anything like it, sir." the soldier explained. "It's coming in on our dedicated frequency. Sir, they want to talk to you."

Bishop lowered his eyebrows.

"I'll take it in the Comm Room." he said.


A little later, a dark in a dark chamber opened up, then Bishop walked into it, as the door closed behind him, then he walked along an invisible path.

"Comm systems, activate." he said, as the room got lighter. "Open secure line, authorization Bishop Omega one zero two."

A hologram of a cloaked green figure appeared in front of him.

"Greetings, Agent Bishop." it said.

"How did you get access to this frequency?" Bishop asked. "How do you know my name?"

"We have been watching you, John Bishop." the figure said. "We know of your abduction by aliens, so long ago. We know all."

"Who are you?" Bishop asked.

"You watch the skies, night after night, looking for your little green men." the figure added.

"Little grey men, actually." Bishop corrected.

"Futilely gathering what technology you can in hopes of staving off invasion, but right under your nose is everything you need." the figure said. "Information that will put you centuries ahead of your work."

"And I'm to believe you're just going to give me this information?" Bishop questioned.

"No, but I can help you get it, for a price." the figure explained, putting his hands together, holding a finger up. "It will be worth it. There is an ancient gemstone encoded with thousands of intricate designs for very advanced alien technology, and I believe you're familiar with the organisation that holds it. They're called...the Foot."

Bishop eyed him curiously, remembering how the Utrom Shredder stole various alien technology after the Triceraton Invasion last year, as well as his spaceship when he had the Saki Mansion raided.


In the Turtles lair, Donnie pounded on the containment unit he was trapped in, as Leo watched with his arms folded. Nearby, Raph was sending punches and kicks at a punching bag, while Elisa was doing some weapon exercises. Leo turned to Donnie's new work area, where Leatherhead worked on a laptop, while Cath sat nearby on a computer.

"Anything?" Cath asked.

"No." Leatherhead sighed, turning around.

Leo stared at Raph, who kept punching his punching bag, before he did two kicks on it, then he held it. He leaned on it and sighed, as Elisa twirled around and slashed her Kamas around three times, before she stopped and panted.

"Ah!" she sighed, wiping sweat from her forehead with her arm.

Mikey poured some juice into a cup, which he put on a tray, with also had a bowl of 'Yummy Flakes' and milk.

"Huh?" he muttered, putting the jug down.

He stared at Donnie, who began clawing at his prison, wanting to get out.

"Do not despair, my son?" Splinter asked, touching Leo's shoulder, getting his attention. "Where there is life, there is hope."

"I keep turning to ask Don what we're gonna do, to see what brilliant cure he and Cath's built up to fix this, but then I remember, that is Don." Leo sighed. "And by the way Cath looks, I doubt she's had any luck."

"No, I'm not." Cath sighed, working at the computer. "I just don't how to turn Donnie back to normal. It's nothing I've ever seen before. Having Donnie's mind would've really helped."

"I too wish to consult with Donatello regarding his mutation." Leatherhead said, typing on the laptop. "He did the majority of the work on the Outbreak virus. Without him, I fear our process is too slow."

The screen showed Donnie's stats and condition.

"Donatello's condition grows worse by the minute." Leatherhead sighed, as Splinter came up behind him. "The Outbreak strain is reacting violently with the Utrom mutation in his blood. His cells are breaking down. It's only a matter of time before he is lost forever."

"That's not gonna happen!" Leo assured.

Splinter, Cath and Leatherhead all turned to him.

"We can't let that happen." Leo said, holding his fists up.

"Leo, it's not that easy, especially without Don. He's the main scientist in the family, while I'm a Doctor." Cath sighed.

"Cath, you both worked together to cure people before." Leo said, recalling their friends that were trapped in the underground city for a time. "I'm sure you can manage with Leatherhead."

"We're trying, Leo." Cath swore. "But it's complicated."

"Every solution has a problem." Splinter quoted. "Every question an answer. Perhaps we are asking the wrong questions. Donatello told me this Outbreak was artificial, that Agent Bishop created it."

"And if Bishop created it, maybe he can un-create it." Leo suggested.

"Bishop is a dangerous man, Leonardo." Leatherhead reminded him.

"I know, but we may not have a choice, especially if Donnie's running out of time." Leo sighed.

They all turned to Donnie, who kept pounding on the containment unit.

"Catharina, how do you feel about this?" Splinter asked.

"Bishop is the last person in the world I would trust, but I think Leo's right." Cath sighed. "It might be our only chance."

Donnie stopped pounding on the containment unit and sat down.

Mikey approached him carefully with the tray of food, which he then put down in front of the containment unit.

"Rest easy, Don. We're gonna find a way to help you." he promised.

He picked up a small remote on the tray, then pressed a button on it, opening up a small hatch. Donnie's eyes widened as Mikey began to push the tray through the hatch.

"It's your favourite, Donnie." he said. "When you wake up, you can-"

Donnie knocked the tray aside, making Mikey get up in horror.

"Ah!" he flinched, before Donnie grabbed his leg. "AHHH!"

He screamed as he tried to move his leg, wobbling slightly. He touched it and tried to pull it free from Donnie's grip, but Donnie was too strong.

"AHH! AH! Raph, Ellie, help!" Mikey cried.

Raph and Elisa both ran towards him.

"Hang on, bro?" Raph said, as they grabbed his shoulders.

"We've got you, Mikey!" Elisa said.

They both began to pull to help Mikey get free, as Leo and Cath ran towards them.

"Donnie, let him go!" Leo said. "Let him go!"

"Don, stop this?" Cath begged, as Splinter approached them. "Please stop?!"

"Donatello, hear my voice, my son?" Splinter asked. "Do not let yourself be lost within this form? Hear my voice."

His words began to echo in Donnie's head.

"You do not want to hurt your brother. Relax, let go. Let go, my son." Splinter said.

Leatherhead moved around the containment unit, then turned a dial around, opening up an air vent inside it.

"That's right." Splinter said.

Gas began to move from the air vent into the containment unit, making Donnie roar as it overtook him, then he let Mikey go.

"AH!" Raph and Elisa grunted.

"AH!" Mikey yelped, as they fell over.

Raph and Elisa stopped on their chests, Mikey on his shell.

Donnie roared as the gas kept overtaking him, before he banged on the containment unit, making Leo, Cath, Splinter and Leatherhead back away.

"Uh, what's going on, Leatherhead?" Cath asked nervously.

"He's becoming resistant to the gas." Leatherhead explained. "We will have to work on stronger tranquilizers."

"Okay." Cath agreed.

Mikey, Raph and Elisa all sat up and rubbed their heads.

"I just wanted to give him some food." Mikey explained.

"In that form, I think Don thinks you're a more tastier meal, Mikey!" Elisa scowled.

"That settles it. We're going after Bishop." Leo decided. "We'll make him help Don."

"And how exactly are we gonna find him?" Raph inquired. "Last I checked, he wasn't listed in the yellow pages."

"I know where he is." Leatherhead explained. "Remember, he held me for weeks, torturing me. I vowed to catch up to him one day and even the score. But the journey is long. I fear Donatello doesn't have that much time."

Leo put his hand on his chin.

"You got an idea, Leo?" Elisa asked.

"Yeah. Maybe Donnie can help us with that." Leo said.

They all approached a door, before Leo pressed a button near it, raising it up.

"This is the last thing Don was working on before...before." Leo said, unable to finish.

He flicked a light switch on, turning on a light, which showed the stolen helicopter they'd taken during their last encounter with Stockman. It had changed however, as it was bright green.

"He completely overhauled Stockman's helicopter." Leo explained. "It should get us where we need to go fast enough."

"Did you know about this, Cath?" Elisa asked.

"Um, no." Cath said. "I've been busy worrying on this Outbreak to notice what he was doing here."


Later, in a pond near the pumping station, water began to swirl around, before a small silo showed up out of it. Its hatch opened up, then a platform with the Turtle Copter rose up towards it. Leo and Raph then both powered it up, and began fly it up and away from the city, to meet Bishop.


In the Foot Skyscraper, Karai - wearing her Shredder armour - opened up a door, and walked into the room where the Foot Mystics belonged. She approached the stairs, but saw they weren't on their podiums.

"Mystics, your master has need of you." she said.

The Foot Mystics all laughed as she looked around.

"Our master is the Shredder, not you, little girl." Water sneered.

Metal used his magic and popped up on his podium.

"You are nothing more but a pretender, like the Utrom abomination before you." he sneered.

Karai glared as the other Mystics popped up on their podiums.

"You forget your place, Mystics. You serve me now." she snarled. "I hold the same power over you as my father did. All your talk of ancient power. You live in the past! I am the future and you will obey me."

She held up her gauntlet as the Mystics stared at her.

"Find the Turtle Leonardo, he must pay for his crimes against my father." she said. "Do you hear me?"

She turned around and walked away.

"Find him!" she roared.

She left the room, with the door closing behind her.

"Perhaps he will find you!" Metal sneered.


Meanwhile, Leo and Raph flew the Turtle Copter over the Nevada desert.

"This is it, Groom Lake, Nevada." Leo said. "Prep for landing."

He pressed a button above him, as Raph turned the copter right.

"Wait a minute... Groom Lake, as in Area 51?" Mikey asked, frantically.

"Yep." Cath sighed. "Makes sense I guess, due to who Bishop is."

"And take it easy, laughing boy." Raph said, as he landed the copter.

A little later, as a wolf howled, the five Turtles all peeked over a hill and stared at Bishop's base.

"Eep. Area 51. This can't be right." Mikey said, as they ran down the hill. "Maybe this isn't Bishop's base. Maybe we took a wrong turn... at Albuquerque."

They all stopped by Leatherhead, who stood by the copter.

"This is where Bishop's base is located." Leatherhead assured.

"But Area 51?" Mikey questioned. "All those crazy stories. It's... it's the heart of darkness. U.F.O. central. The nexus of weirdness."

"Then you'll fit right in." Raph joked.

"Yeah, and Cath's got a point." Elisa reasoned. "Due to who Bishop is, it would make sense his base would be around here."

"Why thank you, sis." Cath said.

"Well, weird or not, we're going in there." Leo said. "Straight infiltration. Raph, Elisa, Cath, Mikey and I get in and get Bishop. Master Splinter and Leatherhead will stay with Don just in case. Once we have Bishop, we'll convince him to help Don."

"Leatherhead, Elisa and I can handle that portion of the plan." Raph assured, punching his fist. "We can be very convincing."

"You can count on it, Leo." Elisa assured, cracking her knuckles.

"No mistakes. This is a military base, special ops, Bishop's turf. Be ready for anything." Leo advised.

"We will, Leo." Cath assured. "This is for Don, after all."

Leo nodded.


A little later, the five Turtles all ran towards the fence outside the base, then Leo jumped up and sliced the barbed wire at the top with his sword. Mikey followed him, followed by Elisa, Cath, and then Raph, all landing crouched down in a three-point stance.

"Split up and scout the perimeter." Leo said, as they got up and ran in different directions. "Let's see what we're up against."

Leo and Cath both jumped over a fence together, then they approached an open hanger, before stopping in front of it.

"Guys!" Leo hissed.

His siblings all gathered around him and Cath.

"Okay, you got me. I wasn't expecting this." Mikey admitted. "The place is deserted."

"I'm not sure." Cath said. "I'm getting a bad feeling about this."

Leo motioned for them all to move towards the hanger, which they did, then they entered the hanger.

"I'm telling you; Area 51 is bad news." Mikey said, entering last. "Aliens check in, but they don't check out."

"Stifle it, Mikey, I'm warning ya." Raph said.

"Yeah, and be quiet!" Elisa hissed. "You want Bishop to find us before we find him?"

They all kept walking before Leo stopped and flinched, making his siblings stop as well.

"Leo, what it is?" Cath asked.

"I think you'll find out." Leo answered.

A light shined from the ceiling onto Bishop, wearing his trenchcoat and battle gear.

"Bishop!" Leo hissed.

Bishop grinned as the Turtles took out their weapons.

"Welcome, Turtles." he said. "I must say, I'm surprised to see you. We don't get a lot of guests, here."

"Oh, I knew this was too easy." Raph said. "You think they saw the copter?"

"It's Area 51. They probably have a U.F.O watching us from space." Mikey guessed.

"Not exactly, Michelangelo." Bishop said.

"Then how'd find out we were coming?" Elisa asked, annoyed.

"We detected the helicopter as it approached because it's my helicopter, Elisabetta." Bishop explained. "Dr. Stockman took it to New York on his ill fated trip."

He pointed at him with his hand as Stockman came into the light.

"Stockman? Still alive?!" Raph exclaimed. "I thought we were done with you for good?"

"Same here. You're worse than a cat, Stockman." Elisa joked.

"Oh, I wish, but Agent Bishop didn't see fit to let me rest in peace." Stockman explained. "So you might say, he's made me have more lives than a cat."

"Enough chit-chat." Bishop said. "What brings you Turtles to my house?"

"There's been an outbreak in New York caused by your alien invasion force." Leo explained.

"I'm familiar with the situation in New York." Bishop assured.

"Oh, so you know about it, huh?" Elisa inquired. "Ha! Surprised you haven't done anything about it?"

"To be honest, I have been." Bishop assured. "But I sense there's more."

"Don got infected. He's been transformed into...into a monster." Leo explained.

Stockman laughed. "Oh, that's rich." he mocked. "So much for the smart one."

"Don't you dare say that, Stockman!" Cath snapped, angrily.

Stockman turned to her as she glared at him.

Bishop lowered his goggles.

"Perhaps we can be of aid to one another. What if I told you I could cure your brother?" he said.

"Why would you help us?" Leo questioned.

"I would help your brother because I require something from you in exchange." Bishop explained.

"You mean like, a deal?" Cath inquired.

"In a manner of speaking, yes." Bishop answered.

"There is no way we should make a deal with this guy." Raph said.

"Don's in trouble because of Bishop, and he tried to dissect us, remember?" Mikey recalled.

Leo sighed, seeing no other option. "It may be a deal with the devil, but what choice do we have?" he said.

"Leo's right." Cath sighed. "I hate Bishop the most, but I don't think we have another choice here."

"As much as I hate this, I agree." Elisa sighed. "Unless you guys have a better idea?"

Raph and Mikey both glared at her, but they didn't have another plan, making Bishop smile.


Later, four E.P.F soldiers escorted Splinter, Leatherhead and the Turtles down a road away from the main gate, which closed. A searchlight followed them along, right on Donnie's containment unit, which was on a trailer. Donnie roared as they approached the hanger, then the door opened up, then they all walked inside, as Bishop stared at them from a catwalk above. He looked at them all as they approached a sphere container like the one Toad was in, before they stopped right next to it.

Leatherhead looked at Donnie sadly, before he turned and looked up at Bishop.

"You!" he hissed.

He growled angrily as the Turtles grabbed him, Leo his chest, the others his arms.

"Easy, Leatherhead." Leo said. "Remember why we're here."

"We're here to help, Don." Cath reminded him. "Now's not the time."

Leatherhead clamed down and snapped his mouth.

"Humph. Where did you get this pathetic containment unit, in a junkyard?" Stockman asked, walking past them towards it. "Amateurs. Ready the cell for transfer!"

The four E.P.F soldiers moved to a corner of the trailer, then used long tasers to move it closer to Stockman's containment unit. Splinter, Leatherhead and the Turtles moved away, before the soldiers all stopped.

"Dr., is this transfer necessary?" Bishop asked.

"It is if you want more than his blood pressure and temperature." Stockman explained, turning to him, before turning back around. "Now open that hunk of junk."

One of the soldiers crouched down near Donnie's containment unit, then pressed buttons on it, creating a forcefield barrier between the two containment units. The door on Donnie's opened up, before he began slowly moving through the barrier, as the other containment unit's door opened up. The E.P.F soldiers began tasing him with their long tasers to get him to move, but he grabbed two of their tasers and made them tase the barrier, shattering it.

"AHHH!" the soldiers yelled, as they got shocked.

Donnie turned around to the other soldiers and roared, before they both tased him, pinning him against the sphere containment unit.

"Stockman!" Bishop yelled.

The Turtles, Splinter and Leatherhead looked horrified.

"Don, don't!" Mikey said.

"This isn't good." Cath gulped.

Donnie pulled off the door to the sphere containment unit, shattering part of it, then he knocked the two soldiers away with it, while roaring.

"Oh, crud." Raph mumbled.

"Good one, Stockman." Mikey said sarcastically.

Donnie roared and threw the door at Leatherhead, knocking him away as the Turtles turned to him.

"Leatherhead!" Cath cried.

Leatherhead hit a wall, then fell onto his chest.

The Turtles all turned to Donnie, who turned and roared at Stockman, before picking up part of the containment unit, holding it over his head.

"No, stop?!" Stockman begged.

Donnie whacked him with the glass, knocking him away, making him bounce between four soldiers, who then fired at Donnie.

"No! No shooting!" Leo begged, as Donnie deflected some of the blasts with the glass.

Donnie charged at the soldiers, then whacked three of them away with the glass, while picking the fourth up.

"AH!" the first three moaned.

"AHH!" the fourth cried, as Donnie threw him away.

More soldiers came up behind Donnie, as Bishop watched from the catwalk.

"Reinforcements, immediately!" he ordered.

Doors opened up all over the hanger, then squads of E.P.F soldiers poured into the hanger.

"Modify mission objective!" Bishop ordered.

He jumped down from the catwalk and landed on the floor, before he took his trenchcoat off.

"Subdue the beast!" he commanded.

"Don, hang on!" Raph yelled.

He and his siblings all jumped towards Donnie, who held two soldiers while standing on a third, as more fired their blasters at him. Raph and Elisa then grabbed his arms, as Mikey got onto his shell and wrapped his arms around his neck, making Donnie let go of the soldiers.

"AH!" they grunted.

A soldier aimed a missile at Donnie, before Leo dived down towards him, then sliced it up out of his hands with one of his swords, before he kicked the soldier away.

Donnie roared as Raph, Elisa and Mikey tried to restrain him, as Splinter and Cath approached him.

"Donatello, please? Be clam, my son?" Splinter asked.

"Donnie, please don't do this?" Cath asked. "This isn't you."

Donnie grabbed Raph and Mikey and threw them away.

"AHH!" they yelled.

Donnie grabbed Elisa and held her up, before he threw her away.

"AHH!" she yelled.

Leo dived and pushed Splinter and Cath away as Donnie tried to pound them both.

"Sorry, Master, sorry, sis, but I didn't think that was gonna work a second time." Leo said, as they turned to it.

Donnie roared and approached the three of them.

"I think you might be right, bro." Cath gulped.

A grenade hit Donnie, creating a smokescreen around him. When it cleared, Bishop aimed a his wrist at Donnie, who lay on all fours.

"Bishop, no! Don't hurt him!" Leo exclaimed.

"If your brother cannot be contained..." Bishop began, as the Gatling blaster extended from his wrist. "...then he will be put down!"

He turned to Donnie and glared at him.

"I had hoped we could do business together, but it seems I was wrong." he said.

Leo and Cath gritted their teeth as Splinter gasped, as Bishop prepared to fire.

"AH!" Leatherhead roared, diving towards him.

He landed near Bishop and knocked him away, then he jumped after him, as Bishop landed on his side.

"You will not touch my friend!" Leatherhead said, landing over him. "If he must be subdued, then I will do it, not you, fiend!"

He smashed Bishop's Gatling blaster with his fist as he spoke, then he turned around as Donnie glared at him. They both charged at each other, then Leatherhead dodged right and punched Donnie, before he spun around and hit Donnie's legs with his tail, sending him flying away.

"Leonardo, Catharina, get the tranquilisers." he said, jumping towards Donnie.

Donnie landed on his shell, then got up as Leatherhead pounced on him, then they both began to roll down a tunnel while locked in a grapple.

Bishop and Stockman ran towards the top of the tunnel entrance, then stopped.

"This is Bishop to command, send in two more squads!" he ordered, held his right wrist up, as his men ran down the tunnel. "Lethel force is authorized!"

Leo and Cath both came towards them both.

"Stop!" Leo said.

"Don't!" Cath yelled.

Bishop and Stockman turned to them both.

"Just wait? Just give us five minutes?" Leo asked.

"You have two." Bishop said coldly.

Leo and Cath both turned and ran out of the hanger as quickly as they could.


Meanwhile, Leatherhead punched Donnie at the end of the tunnel, knocking him away towards a wall, which he smashed due to his weight. Smoke came up around him, before he stood up as it cleared, seeing he was in Stockman's main lab. Leatherhead came up behind him and pounced on him, wrapping his arms around his neck, before Donnie grabbed him and threw him to the floor.

"OH!" Leatherhead moaned.

Donnie picked him up and threw him away towards the main area, landing near the dissection table.

"AH!" Leatherhead moaned.

He pulled himself up and rubbed his head, before he saw where he was.

"No! NO! Not this place!" he gasped, dropping a claw he held. "Not again!"

(Flashback)

Leatherhead lay on the dissection table, as several E.P.F scientists stood around him.

(Flashback ends)

Leatherhead gasped as he looked around, seeing saw blades on above the lab area.

(Flashback)

One of the saw blades moved towards Leatherhead, then began to cut him open.

"AHHH!" he yelled.

(Flashback ends)

Leatherhead turned and gasped, seeing more horrible stuff.

(Flashback)

Leatherhead lay strapped to the table, with dental plunger stuck in his mouth, which choked him.

(Flashback ends)

Leatherhead's eyes widened.

(Flashback)

Leatherhead looked up at the lights above the table, as Bishop came towards him.

(Flashback ends)

Leatherhead fell to his knees, his hands over his eyes, horrified by his experiences here. He began to cry when Donnie ran towards him, who roared and raised his arms up to pound him, when two tranquiliser darts hit him, one in the underarm, one in the chest. He turned and saw Leo and Cath standing near Bishop and some of his men, both with their tranquiliser blasters.

"Donnie, we're sorry, but this is for your own good." Leo said.

"We're really sorry, Don." Cath wept. "But it's the only way to save you."

Donnie roared and began charging at them both, as they fired tranquilisers repeatedly at him, hitting his chest, arms and belly repeatedly. After about 14 went into him, he began to slow down, then he fell onto his knees, then onto his chest in front of his siblings, out cold. Leo, Cath, Bishop and the soldiers all gathered around Donnie.

"It's going to be alright, Donnie." Leo promised, touching his shell.

"We promise, Don, we're gonna cure you." Cath assured.


Later, Donnie was in another sphere containment unit filled with water, opposite the one Toad was in. Bishop, Leatherhead, Splinter and the Turtles all stared at him, as Stockman looked at a panel next to it, which showed his readings.

"Hmm? Donatello's body appears to be breaking down at a fantastic rate, due to secondary stage mutations caused Outbreak accelerant." Stockman said. "He doesn't have much time. The animal was right."

He turned to Leatherhead, who growled, as Stockman was referring to him.

"Leonardo, this is wrong." Leatherhead said.

The Turtles and Splinter all turned to him.

"We cannot leave Donatello's fate to these devils. Stockman can not be trusted. " Leatherhead said, pointing at him, before pointing at Bishop, who'd turned to them all. "And him. If you only knew what he was capable off."

Bishop folded his arms.

"Leatherhead's right, Leo. Bishop's the enemy! He's the one that caused the outbreak in the first place." Raph said.

"Don't you think he knows that, Raphael!" Cath snapped. "We all know that, but we don't have another option here!"

"Stockman created the genetic accelerants on my orders." Bishop admitted. "What you call the 'Outbreak Virus' is an unintended side effect of one of my operations."

He pointed at Todd, as both he and Donnie floated in their containment units.

"Do you have a cure?" Leo asked.

Bishop looked at all the Mutants, then to Stockman, who shook his head.

"Yes." he lied. "But as I said earlier, I need something from you."

Splinter huffed as Mikey and Elisa flinched.

"Name it." Leo said.

"A simple errand, really." Bishop explained, turning back to Todd, approaching him. "There is an item I require. A relic that may prove crucial to my work. I want you to retrieve it for me."

Leo turned to his siblings, who all turned to him.

"Retrieve it?" Leo questioned, as they turned to Bishop. "From where?"

"New York. In fact, I believe you know the woman who currently holds it." Bishop said. "Her name is Karai."

He turned to the Mutants, who all gasped in shock and surprise, but knowing Donnie's life was at stake, they had to go with the deal.
