Mikey slept on the couch, pizza box on his head and a half eaten pizza in his mouth. Raph trained with the shredder dummy, punching and kicking it so hard it'd fall off the stand. He yawned and looked over at the couch as Leo was cleaning up Mikey's mess.

The red clad turtle walked over and carefully lifted up Mikey to carry him to his room.

"What are you doing?" Leo looked at him.

"Just gonna carry him to his room, what's it to ya?" Raph gave him a look.

"Let him sleep." Leo glared back. "Put him down."

Raph rolled his eyes and laid Mikey back down and walked to his room. When he was out of sight, the blue clad turtle scooped Mikey up and carried him to Leo's room. He laid him in his bed and laid beside him and held him to his chest, feeling Mikey snuggle into him.

Mikey woke up and saw he was in Leo's bed and his arms were around his waist. The pulled away but Leo pulled him back, still asleep.

The orange clad turtle moved out of his arms and walked out and to the kitchen, seeing Raph feed Spike.

"Hi, Raph." Mikey started making coffee for when Donnie came in.

"Hey." Raph patted Spike's head and looked up at Mikey. "You know what Leo's deal is?"

"What do you mean?" The younger turtle looked at him.

"He's so... defensive over you. It's weird..." Raph shrugged.

"Maybe he's just being a protective brother." Mikey suggested.

"I don't know. He's protective over you even when it comes to me or Donnie." Raph shook his head.

Leo walked in and sat down at the table and Raph avoided looking at him.

"Morning, Leo." Mikey smiled at the blue clad turtle.

Leo blushed a little and smiled. "Morning, Mikey. Raph." He said Raph's name as if he were holding a grudge against him.

"Leo." Raph gave him a look. He stood up. "I'm gonna go get some fresh air."

"I'll come with." Leo stood up.

"But you guys didn't eat yet!" Mikey frowned after having made them pancakes. "They never eat my pancakes ;-;"

Raph stormed up to the surface, Leo following. The blue clad turtle pulled out some rope from his grappling hook and grabbed Raph.

"Leo, what are you-" mid sentence, Leo started choking him with the rope.

"He's mine." Leo growled and pulled on the rope tighter till there was no struggling movement coming from Raph. He tied the rope around his neck and dragged him down in the sewers and to the garage and hung Raph from the entrance to make it look like suicide. Then he took a shuriken and stuck it in his lower abdomen to make it look like it was thrown at him. Leo snuck back around and ran in.

"Leo, where's Raph?" Mikey looked at him. "What happened to you??"

"That's the thing I don't know. I wanted to talk to him and he threw a shuriken at me and ran off. I can't find him anywhere." Leo spoke quickly as if he were scared.

Donnie's shocked screams rang out and the two turtles rushed to the lab and saw Donnie covering his mouth and point to a hanging Raphael.

"Oh my god." Leo covered Mikey's eyes before he could see it. "Why would he-..."

Donnie pulled Raph down and saw the knot of the noose was right behind his neck instead of to the right slightly. The purple clad turtle looked over at Leo and saw the shuriken in his side and by the looks of it it seemed like it was thrown by a leftie.

"Leo, what happened to your side?" Donnie asked.

"Raph threw a shuriken at me while I was trying to talk to him. He ran off and I guess he did this..." Leo muttered.

"Leo, Raph's right handed." Donnie shook his head.

The blue clad turtle looked down at his side and realized he messed up. He had stuck it in his right side and paid no attention to the fact that hand Raph would have used his right hand if he were to throw a shuriken at him.

"Not only that, but Raph didn't do this to himself. The knot would've been over his right side since he's a righty. But the knot is behind his neck completely. Someone else hung him." Donnie explained.

"What are you trying to say, Donnie?" Mikey asked, shaking slightly.

"Leo... did you kill Raph...?" Donnie whispered.

Leo glared at him and pulled the shuriken out of his side and pushed Mikey behind the desk and stabbed Donnie in the gut with the shuriken.

Mikey sat up and looked over and his eyes widened at what Leo was doing. The blue clad turtle smirked over at Mikey and neared him, grabbing his hands with his bloody ones and caressed his face.

"D-Don't touch me!!" Mikey tried pushing him away. "Stop-!" Leo pressed his lips against Mikey's and held him to his chest.

"You're mine forever. No one can have you now."
