Two hours pasted since Raph stormed off so, of course, Mikey begin to worry. He is usually gone for thirty minutes or so and then comes back as cool as a cat. Sometimes, if he was REALLY pissed, he would be gone for a hour but that rarely happened.

Mikey tugged on Donnie's shoulder, unsure about what to do, "Raph should've been home by now..." Donnie quirked an eyebrow, but before he could speak, Leo spoke up without taking his eyes off the television, "Eh, let the baby cry over his spilled milk."
"But..." Mikey's eyes grew big and puppy-like, "What if something bad happened to him..? He could be hurt..." Leo turned to look at his sad, baby blue eyes. Leo sighed in defeat and grabbed his katanas. "Alright, let's go." Well, that was quick. I thought it was gonna take some serious convincing.

"Wait, I'm confused," Donnie said, "Did I miss something?" The turtles ignored the brainiac and went on their way.

"Let's split up, we'll meet up here in a hour." All three turtles nodded and ran off in different directions.

The first thing Mikey did was call Raph on his T-phone. He didn't pick up. Mikey frowned and thought that something really bad must have happened to him. Maybe he got captured or ambushed by the Foot. Or even worst, he could've been eaten by a giant pink raccoon!

Mikey jump from rooftop to rooftop, heading to his and Raph's special hangout which sat at the edge of the city. When he got there, he felt like his older brother has been there recently, his ninja senses were going off the charts. He observed the rooftop carefully, trying to find a trace of Raph's existence. Finding nothing but marks on the walls, he begin to turn around and look for him somewhere else when suddenly, in the corner of his eyes, he spotted something shiny. He turned around and spotted one of Raphael's sais. He slowly lifted it up, feeling a tear in his eye. Was he... No... It can't be...

Mikey quickly ran back to the meeting spot, texting both Donnie and Leo to come back. It only took a matter of minutes until all the turtles to come back to meet up.

"What's wrong, Mikey?" Donnie asked. Mikey looked down to the ground and lifted his hand, revealing the sai. Leo became wide-eyed as he snatched the weapon from his younger brother. "W-Where did you find this..." Leo's voice cracked as he spoke.

"We have a spot at the edge of the city where we hang... I found it there..." Mikey whimpered, tears in his eyes, "Dudes... I'm scared..." Leo and Donnie comforted him by wrapping their arms around him and telling him it was going to be ok and that they were going to find him.

After what seemed like hours, they were able to calm down Mikey and head to the building. They couldn't find anything much when they got there but a few burn marks on the floors and walls. "Raph must've got into a fight." Donnie said, observing the marks.
"But with who?" Leo asked, "These marks don't look like something Kraang guns could make. Same with the Foot."
"True, but look at the pattern of the marks." Donnie pointed at one of them, which was making complicated patterns of what looked like lightning, "Maybe the Kraang upgraded their weapons. Probably guns that shoot down an enemy using electromagnetism."

"I don't know what that means but they have Raph..." Mikey said, "I hope he's ok..."
"Of course he would be ok, Mikey, he's Raph, he'll find way." Leo said, comforting his youngest brother. Mikey let out a chuckle, "Yea, but we still need to find him." All three turtles nod in unison and looked around for more clues.

Well, while they scavenging around for answers, lets go back to Raphael, shall we?

Raph slowly opened his emerald eyes only to see darkness. He was in one of the most uncomfortable positions ever. Well, he was in a small, thin glass tube so that would explain it. "Where... Where am I..?" He asked himself, trying his best to stand up. Green orbs observed the dark lab-like room.

The lab was full of machines and devices that even Donnie wouldn't know about. But despite it being full with hell knows what, there were no Kraang bots or humans around. He certainly wasn't in Kansas anymore.

He started to bang on the glass, but it awfully hard without hitting yourself in the face, but he dared to anyway. He constantly yelled insults at nobody in particular, often yelling things like 'boneheads' or something in that matter.

After constant minutes, groups of Kraang bots piled into the cramped the room. "THE ONE KNOWN AS RAPHAEL HAS AWOKEN." One of the Kraang bots. Raph growled, "Hey, let me out so I can smash your heads in the wall! I have rights, you know!"
"INCORRECT. THE ONE KNOWN AS RAPHAEL HAS NONE OF WHAT YOU CALL 'RIGHTS'."
"I can't believe I'm having this conversation with you."
"KRAANG CAN'T EITHER."

A Kraang bot stepped closer to Raph, "THE ONE KNOWN AS RAPHAEL IS REBELLIOUS TO KRAANG. CORRECT?"
"Um... Sure, I guess. Can I go now?"
"NEGATIVE. THOSE WHO REPEL AGAINST KRAANG WILL WORK FOR KRAANG." Raph busted out laughing, "Ha, good luck with that. There's no way that I would work for the likes of you."
"KRAANG THOUGHT YOU WOULD SAY THAT." The Kraang bot walked toward a lever beside the test tube.

"W-What are you doing!? Don't flick that switch!" But it was too late. Raph looked up to see gallons of mutagen about to pour all over him. As soon the green goo landed all over his green skin, screams emitted from the tube.
