Thirteen: A fight between sisters

''Caitlin? Oh my God Caitlin!'' Karai raced over to her, helped her up and hugged her.

''I've been looking everywhere for you!'' Caitlin smiled, ''Hi Karai, I've missed you.''

''And I've been worried sick! what happened? Shredder said you betrayed us, but I knew it wasn't true. What happened the night you fought Shredder?''

Caitlin sighed and explained everything that happened to her. She even told her the truth about Shredder and Karai couldn't believe what she was hearing. ''Caitlin no, that's not true, the turtles must have tricked you. Come on I'm taking you home.''

''No Karai, I haven't been tricked, it's true.'' She sighed, ''he even admitted killing my parents.'' Karai looked at her, and Caitlin could tell she didn't believe her. ''No, Caitlin that can't be true. Your my sister and I'm taking you home.''

''No, no Karai listen to me I'm not going back, Shredder is lying to you, he lied to me, you have to believe me. Come with us, you'll see what I mean so we can stop him.''

''No I don't think so.'' Caitlin frowned. ''Why don't you believe me?''

''Because Shredder is our father. Splinter killed my mother and he said he loved us and never would hurt us like that.''

''It's a lie!'' she lifted up her shirt sleeve, ''I've got the scars to prove it. For every time I've failed him. Where are you scars?!''

Karai didn't answer her. ''Please, please Karai join me and-'' ''No Caitlin. Your'e coming home with me, and I'm taking not taking no for an answer.'' She took out her sword and charged for her.

Meanwhile, the turtles were still trying to hold their own while trying to get to Caitlin.

The fight wasn't easy, the Foot Bots weren't backing down. Leo was trying to find Caitlin, but it wasn't easy with the Foot Bots attacking them every time he turned around.

Donnie wasn't doing good either, the Foot Bots kept tackling him to the ground, while Mikey was trying to help him and Raph was having as much luck as Leo.

Leo kicked off two more Foot Bots and looked over at the next rooftop, eyes wide when he saw Caitlin fighting Karai.

''Guys Caitlin is in trouble!'' ''sorry Leo,'' Raph said as he kicked another Foot Bot away ''but we got our own problems at the moment.''

Leo tried his best and tried to help her, but more Foot Bots got in his way. ''Donnie I need a little help here!'' ''I'm trying!''

''Oh for crying out-'' Leo flipped over the other Foot Bots and took them out and then helped oy his brothers.

Raph started working with Donnie to take out some bots taking them out one by one. Leo and Mikey were doing the same thing working together. The four of them switched back and forth taking down all the bots while Leo hoped they could make it to Caitlin on time.

''Karai stop this!'' ''I don't want to hear it!'' Karai said as she charged for Caitlin again.

Caitlin was still trying to get Karai to listen to her, but she didn't care. All she wanted to do was take Caitlin home with her.

Caitlin backed away as she slowly took out her tanto. ''I don't want to fight you Karai please just-''

''Enough Caitlin, the turtles are lying to you, can't you see that? I don't want to fight you either, but if you won't come home with me, I'll just have to make you.''

They charged for each other, and started fighting. But then Caitlin tripped. Karai walked slowly towards her and was about to attack her but something hit her knocking her to the ground.

''No one hurts my sister.'' Caitlin saw it was her brother who helped her up. ''And you told me not to worry.''

''Sorry, but I didn't think this would happen.''

''So, who tried attacking you this time?''

''The girl who used to be my sister.'' Karai stood up, turned and couldn't believe her eyes.

Chris looked at the girl in front of him and was shocked as well. ''Chris? what's wrong?''

''Alexa?''

Karai stared at him, shocked. ''Chris? she's your sister?''

''Chris what's going on?''

''It's Alexa,'' he replied. ''The girl I told you about. What are you doing here and why did you attack my sister?''

''I should've told you I'm not who I seem. My real name's Karai.''

''Wait, your the girl that tried to kill my friends?'' he asked and then realized something. ''You've been lying to me all this time, why?''

''So I could find her,'' she said pointing at Caitlin.

''Why?''

''Because she was my sister first.''

''Not at birth you weren't. Why did you attack my sister?''

''Because I was trying… to get her to come back with me.''

''I'm not going back Karai. Shredder has been lying to you to, I know it, all you have to do is come with us and we can work together to stop him.''

Karai stared at them. She didn't know what to say to them. So she dropped her sword and walked away.

Caitlin stared after her,''Karai wait!'' but then they heard police sirens and the turtles joined them.

Leo took her arm, ''We have to go Caitlin.'' Caitlin stared after Karai for a minute before she nodded and following them. As they retreated, but not too far away Karai looked on from another building, with one thought racing through her mind, now what?
