Welcome back to everybody to the story, last time we saw that Mutagen Man had learned to literally extract mutagen, pretty serious stuff. But how will this impact everyone as a whole? Also, Leo, Mikey, and Raph made a huge blunder while trying to find their brother Donnie, and ended up in contact with Mr. O'Neil. How will they handle this mistake? Let's find out. As always, Ninja Turtles does not belong to me and all rights go to their respective owners. So let's go!

Chapter Ten

Casey and April were trailing the sewers for about twenty minutes as April continued to have her eyes glued to the tracker in her hands, keeping an ear on the beeping being made.

The tracker remained steady and strong the entire trip hoping they would find her dad through the outstrits of the sewers...and then suddenly, the signal died. Dead silence.

The two of them stopped as April gently shook the tracker hoping it would start back up.

"I don't get how we lost the signal? It was going crazy, then it just...died." April complained, now starting to bang on the object. Casey then took the tracker and looked for where the batteries would go, quickly realizing that he didn't have a clue what he was doing.

"Maybe your dad just stopped using radar..." Casey threw out a winged guess, which April shook in responce.

"No, bats need to use their radar all the time to detect where they are." April responded sounding very tech like, which Casey raised an eyebrow from her answer, wondering how she would know such information.

Then the light bulb went off in his head.

"Don-Boy taught you that, didn't he?" Casey asked.

She paused for moment, remembering the saftey of her friend. "Yeah he did. I hope he's alright..." She followed with a sigh. The two started to trail slowly, now as if finding her dad had become secondary. She was really hoping her friend was alright.

Casey was looking to her for the whole trip now, her eyes broken, her face in a constant frown. He knew this probably wasn't the best time to talk about this, but he became curious. "Why didn't you ever tell Don-Boy about us Red? I mean, I know he likes you and all, but...he's a turtle. A mutant turtle at that."

She stopped and turned to him, thinking the same thing Casey was thinking: "Why did I ask this?"

She knew he had every reason to wonder, but she also knew that Casey could never comprehend the friendship between her and Donnie. Heck, she was friends with Donnie before Casey even thought of the notion of mutants being in New York.

"It's...complicated Casey." She started.

While she became friends with all the turtles, she connected with purple turtle the most. She always believed that while her father was gone for a majority of the time she knew her mutant friends, Donnie reminded her the most of her father. "He's saved my dad's life, and he's saved my life, a bunch of times. After everything he's done...I just don't know how to tell him."

Much like Donatello didn't know how to tell April his feelings for her. For everything that happened to April, whether directly or indirectly, April knew that Donnie would feel he would be taking advantage of her when she was vulnerable if he had confessed to her his real feelings. So Donnie wanted to wait for that perfect time to tell her...but it never came. It was just one thing after another. Her dad, Timothy, a retro-mutagen; some road block always stood between them. It almost came to a point where April didn't care anymore, and deep down just rooted for Donnie to pull through and tell her the truth.

But he couldn't...just like she couldn't.

"You still like him don't you?" Casey almost telling her more than asking her.

"Not now Casey, please!" April so wanted the conversation to end, but Casey slipped the tracker out her hands.

"And you don't wanna hurt him...I understand." Casey followed up, but April turned around in a beat.

"I said drop it!" April snapped as she snatched the tracker out of Casey's hand again and then walked away from him, but then she stopped and turned back. "And trust me...you'll never understand!" And she then walked off again, leaving Casey behind as Casey did his best to shrug it off. After an aukward silence, Casey needed to change the topic in a hurry.

"So...what's the deal with the guts in a jar?" Casey said in a fairly cracked tone, wondering if he should say anything else. April did turn to him in a bit of resent, but the look on his face seemed sincere and she turned back to where she was going. And after a delay...

"Based on what Donnie told me in the past, that thing used to be...his friend." She trudged along looking at the tracker still hoping it would pick up something.

"Friend like that, who needs an enemy." Casey added on.

Just when the two were about to give up hope.

*BEEP...BEEP...BEEP*

Casey looked over to see the gizmo react to something as April observed as well.

"The radar tracker's going off again. It's a weak signal, but it's responding." April looking down, beginning to pick up the pace.

"April! Up ahead!"

April looked up at Casey's warning and what she envisioned was her father hiding in the under skirts of the city sewers, but that's not what she saw. It was much worse.

The two saw a huge opening in the sewers which appeared to be a previously destroyed subway station that was nothing but remains. And in the middle of the huge area, was a non-moving turtle, laying face first on the ground.

April gasped in horror at the sight.

"Donnie!?" She sprinted to the fallen turtle as well as her friend. He still wasn't moving as Casey was close behind. She looked at the tracker and the tracker was clearly reacting to something where they were. But Donnie was the only thing that it could react to. "Donnie's the radar signal?" April said in pure befuddlement.

"That's strange. Turtles don't use radar." Casey enlightened, or at least what he was pretty sure of.

"Unless..." April began to wonder as she looked at the tracker in her hand. "...unless this is the mutagen tracker..."

It was the only other reasoning that it could be, but if so, something still wasn't right.

"How can it be? Donnie's barely giving off a signal."

"True." She agreed as she wanted Casey to flip Donnie gently on his back. He did so as easy as possible as she held the tracker towards Donnie's heart. Sure enough.

*BEEP...BEEP...BEEP...BEEP*

The signal was weak, very weak. There was no other recourse though. If they had the radar tracker as they thought, the signal would be completely dead. It clearly was the mutagen tracker, which made April and Casey even more worried in truth.

April lent her ear to Donnie's chest and shell, hoping to hear a heartbeat as Casey kept him pearched up resting him on Casey's knee. Thankfully, she could feel his chest slightly uplifting, though he showed no sign of reaction or response to anything the two had done, a slight sigh of relief came to the teenage girl.

"He's still breathing...wait."

She paused and realized something that she wasn't thinking of. She looked down at the tracker in her hand.

"If we have the mutagen tracker, that means the guys have..."

She gasped. "OH NO!"

Mr. O'Neil continued to carry Michelangelo higher in the sky as Mikey feared for his life as he screamed through the air.

"Can't we just stop and talk?" He hollared up the bat that was carrying him by the arms who then screeched in responce, which put a sheepish grin on the turtle's face. "Sorry, I forgot!"

He looked down from high above seeing little specs that were his two brothers jumping from roof to roof building trying to keep up with him, but there was only so much they could do five hundred feet below him. He had to find a way to escape Mr. O'Neil's grasp as he looked down seeing that his nunchucks weren't with it, but saw something else.

"I got an idea...hey Kirby Bat." Mikey yelled and got the bat's attention as he whipped out a smoke bomb that he always had on him.

"Take a whiff of this!" And threw into the bat's face. It blinded the mutant bat and released Mikey, Mikey's plan work.

But the bat released him while five hundred feet in the air and Kirby Bat flew off. Mikey's plan didn't work...as he looked down in horror.

"Okay, that plan sounded better in my HEAD!"

And Mikey began to freefall to the city below.

Raph and Leo looked in terror as they saw their little brother falling from the sky at a quick pace, they could see him trying to flap his arms like a bird, to no avail. The two were in a mad dash screaming out their brother's name.

They stayed close enough behind them that Leo and Raph were close to where Mikey would come down, but there was no building close enough to jump to, nor was there a building below for Mikey to land on. It was soild rock, pavement.

"Mikey!" The turtle in red called out, fearing there was nothing he could do.

"Raph, we need to work together!" Leo told him trying to come up with an idea, but Raph was too much in panic to play along.

"You need to stop talking! I gotta save Mikey!" Raph then turned to his brother and argued back.

Mikey could see his brothers in a banter below, which made him want to pull his non-existing hair out.

"Guys...better hurry before I'm gonna be flatter than a pizza!"

"How am I gonna reach him!" Raph said to himself, until his brother spoke up.

"Raph, charge me!" Leo ordered.

"Knock it off Leo!" His brother rebutted.

"Raph..." Leo caled out again, which Raph turned to his brother who was standing next to the buidling's edge and squatted down. "Charge me!" He ordered again.

The light went off in Raph's head, he understood what fearless leader wanted. Raph pulled Mikey's nunchucks, specially for Mikey's kusarigama chain, and then in a flash, ran at his brother in blue as fast as he could.

"AHHHH!"

Raph jumped onto Leo's hands and Leo vaulted his brother as far as he could. Raph reached and stretched through the air as his falling brother was nearing closer.

"I NEVER GOT TO SEE PARIS!" Mikey screamed out knowing he would hit the pavement, and then he hit something with his eyes closed, he opened them to see his brute brother's arms "Raph!"

"Hold on Mikey! We ain't safe yet!" Raph told Mikey who gripped his brother hard. Raph had Mikey's kusarigama chain and sent it flying as it chained and latched on to the top of a railing of the tallest building around them, but it swiftly slid off and the two brothers continued in a fall.

"AH SEWER MUFFINS!" Raph screamed, looking like he was about to wet his shell.

Just then, Mikey snatched his signature chained weapon from his brother.

"Amateur!" Mikey mocked out as he spun it like a laso and flung it out. The chain spun around a railing of a fire escape and Raph closed his eyes and screamed.

The chain caught and the two swung mere feet before hitting the ground and then the two rolled in an abandoned alleyway.

Raph was shaking in fear thinking he was dead, until he slowly opened his eyes, and seeing he wasn't dead at all, not even hurt. Then looking above him and seeing his youngest brother standing over top of him.

"Owned!" Mikey pointed right in Raph's face, who had his jaw nearly to the pavement belong.

"Guys, you alright!" Came a voice from the buidling above, jumping down as quick as he could. The turtle in orange was fast to give an answer as Raph was busy kissing the ground he was on.

"Of course, as if there were any doubt? I...am...the hero." Mikey praised as he was about to break into a victory dance.

"You're also the one who grabbed the "Radar Tracker" and caused us to get attacked by Mr. O'Neil." Leo filled in on the reality, sending Mikey into a slump.

"Buzzkill!" Mikey moaned.

Raph finally got to his feet, and finalyl caught his breath having witnessed his and his brother's near death expierence.

"Well now that we know what we don't have. Let's find Pulverizer and find Donnie." Raph told his brothers.

Just then though the ground below them started shaking and they looked over to the man hole cover that looked like it was about to pop. Then out of nowhere, the cover was punched into the air, along with part of the pavement as a huge hand busted the opening wider, allowing a huge ooze hand and body come out from the hole.

It was Mutagen Man coming up to the surface, as he turned around to see three mutant turtles before him.

After an ironic pause...

"Well that was the quickest search in the history of the world!" Mikey pointed out.

"Turtles! Turtles mean more mutagen!" Timothy cried in delight pounding his ooze fists together.

The turtles whipped out their weapons knowing that while one battle just ended, another was about to begin.

"Tell us where Donnie is, and maybe we won't hurt ya!" Raph warned as he pointed his sais in Pulverizer's direction. But the monster just grinned evily.

"Mutagen Man tell you, after me have mutagen...snack!"
