Meanwhile, back in his lab Baxster was once again trying to create some retro mutagen. 

"Dexter!" Raphel yelled crashing through Baxster's lab doors.

"Now what?" muttered Baxster frustrated that his work was constantly being interrupted by either the Shredder, his lackeys or the turtles.

"Where is she Dexter?" Raphael growled.

"How many timezzz must i tell you the nameszzz not Dexter its Baxster?"

"Yeah whatever, now answer the question before I squash you like the bug you are! Where is Cat?"

"So, thats why your here." Baxster said  with a slight smile. "To be Catherine's Knight in shining armor and rescue her from certain doom? Hate to beak it too you but she hates you! She wants nothing to do with you mutant freaks!"

Raphael could feel himself starting to loose his temper. "Look who's calling the kettle black." Raphael said grabbing Baxster by his lab coat. "Now I'm only going to ask you one more time and then I'm gonna squash me a bug. where is she?"

"I'm right here turtle." I said with a growl showing up out of nowhere. Before Raphael could react I kicked him in the back of his shell sending him flying across the room.

"Right on time princess" Baxster said with a smile.

I gave Baxster a wink as I walked over to the now almost unconscious Raphael. "What to do with you? I could kill now and be done with it but I'm sure my father will have a much more painful plan for your destruction."

Raphael looked up to see me looming over him he reached out his hand towards me "Cat" he moaned as he blacked out. He woke to find himself in the jail cell next to Karai. "Oh my head" he groaned. "What happened? Where am I?"
"Your in the dungeon in the foot headquarters Raph." Karai replied.
Raphael searched his surroundings. "What happened? How did I wind up here?"

" You got your butt kicked by a girl that's what happened.  Your friend, who you came here to save betrayed you. She's the reason your in this prison cell." Karai replied

"Where's Cat?" He said searching the room.

"I wouldn't be concerned about her if I were you."

"Well look who's finally awake." I said in an almost unrecognizable voice.
Raph searched to locate where Cat's voice was coming from and he finally spotted her leaning agents the wall in the far corner of the room and she wasn't alone.

"How's our guest?" asked the Shredder as he walked into the room followed closely by Tiger Claw, Razhar and Fish Face.
"Cat look out!" Raphael yelled slamming up agents the cell door in an attempt to break free and help her.
I glanced in the direction Raphael was pointing and smiled. "Good morning Father," Catherine said giving the Shredder a mini bow. "Good morning rabble" I said with a smirk knowing that they hated brung called that.
Razhar and Tiger Claw growled and started in my direction but the Shredder held them back. "Go keep a lookout for the others." he ordered Tiger Claw and Razhar. "They should be arriving any time now."
"Yes Master" Tiger Claw said hitting his chest with his left arm as a sign of obedience. "Yes Master". Razhar said reluctantly. "That brat is worse then Karai ever was" he mumbled under his breath.
"What was that?" I growled glaring at Razhar.

"I said those Turtles are going to wish they'd never heard the name Catherine." Razhar said with a gulp hoping that Catherine and the Shredder would believe him.
"I know your lying to me. That's not what you said and we both know it. However, I'll let it slide this time. I've got bigger fish to fry." Turning her attention back to the Shredder I replied "the prisoner is finally awake father."

Raphael frowned, I was acting really weird. It was as if I wasn't myself at all. What had the Shredder done to me? Raphael was going to find out. "What have you done to Catherine you monster?!"

The Shredder looked Raphael directly in the eyes and replied, "Catherine serves me now."

"Yeah, well I bet that wasn't by choice! You messed with her head somehow!" Raphael replied. "When I get out of here the first thing I'm gonna do is kick your butt!"

To this the Shredder chuckled. "Your in no position to make idle threats. As for your comment that Catherine had no choice in her decision to become my student, that simply isn't the case. I haven't forced Catherine to do anything she didn't want to do. That includes setting this trap for you, your brothers and your master. Isn't that right my dear?"

"Yes Master." I replied with a bow taking my place by the Shredder's side.

"Why? Cat? Why are you doing this?" Raphael asked the hurt showing in his voice.

"Because it's what my Master  wants and because I hate you turtles and your Sensei." I replied.

"You see, she's mine of her own free will. Come daughter lets go catch and destroy us some turtles."! The Shredder said waving his hand towards the door.

"Yes Master." I replied without the slightest hesitation.

It didn't take long for the other turtles to arrive. They stared up in shock when they saw me standing next to the Shredder. It threw them off guard but only for a moment. Soon the battle had begun and it looked like the turtles were going to loose. Their best fighter was locked up and they were cornered. Did that stop the turtles? Of course not. Instead they split up into three different directions. Leo made sure Tiger Claw chased him. Mickey was left with both Razhar and Fish Face and the task of freeing Raphael fell to Donnie.

"Would someone get me out of here!" Raphael yelled throwing himself up against the prison door once more.

"Hold your shell I'm on my way" Donnie replied back.
It didn't take Donnie long to free Raphael. "Now it's a party!" Raph said as Donnie handed him his Sai.
"Hay what about me? You mind freeing me while your at it?"
Raph looked over at Karai "what do you think Donnie? Should we help her?"
"Well, I don't know, rescuing her wasn't in the game plan. We don't know if we can trust her. It wouldn't be the first time she pretended to be on our side."
"Trust me, I I wouldn't life a finger to help the Shredder. He's the reason I grew up without a mother. He kidnapped, me turned me against my own father and imprisoned me when I found out the truth. I'll never be loyal to him again."
"Call me crazy but I believe her" Donnie said.
"All right, but if she turns on us then I'll use your shell as a punching bag." Raph said.
Soon the turtles and Karai were fighting the foot robots. "Someone grab Cat and let's get out of here! Leo yelled.
"I'm on it!" Raph replied evading foot bots as he made his way to me. "Sorry about this kid"'he said as he grabbed her and threw her over his shoulder. "I've got her now let's blow this joint!" Raph called to his brothers.

"No argument there!" Replied Donnie as he threw a small pellet onto the floor filling the room with smoke.

"After them you idiots!" The Shredder yelled but it was too late the turtles, Karai and Catherine were gone.
