Ten: Sibling bonding

Chris opened the door and let his sister into his place. ''Here we are, home sweet home. What do you think?'' Chris brought his sister to his place, which is a two-bedroom, a kitchen, a living room, with a balcony.

Caitlin took it all in and looked around, ''it's not bad.''

''Thanks,'' Chris walks over to his room to get some things. ''One of my adopted parents had a grandmother who liked me and left me a lot of money. She also left me this apartment rent-free, which is great since it gets me away from my adopted family who hate my guts.''

''Oh,'' Caitlin looked at the ground, ''that was nice of her.''

''Well, I was the only one who visited and took care of her.'' She nodded and then looked over at the bookshelf and saw a burnt picture and picked it up. ''Is this them?''

Chris came out of the room with some change of clothes and a towel. He walks over and sees the picture. ''Yeah, it was the only thing they found that wasn't burned down. I've kept it with me since then so I wouldn't forget.''

Caitlin smiled a little. ''That's nice. They seemed happy.''

Chris nodded and there was a silence between them before Chris hands his sister the clothes and the towels. ''Here, sorry I don't have any clothes for women. The shower is over there.''

''It's fine, I-I don't mind. And thanks.''

Chris stayed in the living room while Caitlin took a shower. While she was in the shower, she took a look at her scars she received around her body from years of training, punishments, and fights she has been all because she thought the Shredder was a good man, but it turned out that he was a monster, that took her away from her family, and used her like a tool.

And she was going to get her revenge not matter what it took. Meanwhile, Chris was in the kitchen finishing making some dinner while he waited for his sister to finish.

Soon, Caitlin finally stepped out of the shower, got changed and walked back into the living room.

She sees her brother finished getting lunch together and it smelled good. ''You feeling better? and I hope you like pizza,'' said Chris as he sets the plate with food on it.

She smiled,''a lot better actually, and yeah I love it.'' The two ate in silence until Caitlin spoke up ''so…what do you do around here?''

''Well, I used to deliver pizzas. Now, I'm still working that out.''

''Oh so that's what you used to do. I always wondered before I found out the truth why you smelled like pizza.''

Chris began to laugh. ''Yeah, it wasn't a good job since I had to deal with a horrible boss. ''So, what was it like with you living with a bunch of evil ninjas?''

Caitlin looked down at the ground. ''Well…Shredder was always tough on me and tried to always push me hard because of my powers. But I always had Karai to protect me.''

''Who's Karai?''

''Shredder's first daughter and who I though was my sister.'' Chris got up from his seat and comforted his sister. ''Is that why you went back to see her?''

''Y-yeah and I was trying to get her on my side so we could defeat the Shredder.''

''And I assume you told the turtles about your plan?''

''Well…Leo…and he tried to stop me, but again, me being stupid, I didn't listen.''

''You should have,'' Chris replied taking a bite out of his pizza. ''Going out alone in the condition you were was not a good idea.''

Caitlin frowned. ''Yeah I guess.'' ''H-hey can I ask a question?''

''Sure, what is it?''

''D-do you know what happened to our parents?''

Chris stops eating and stares at his sister surprised. He puts his pizza down and has a sad expression. ''I don't remember much about that night. All I remember is hearing our parents yelling at someone, the fire, and then blacking out. Do you remember anything?''

Caitlin shook her head. ''Nothing at all.'' Except…I should probably tell you…it was the Shredder who killed our parents.''

Chris stares at her, but didn't looked surprised. ''I kind of figured, especially after Leo told me about him. How did you find out?''

''Stockman, Shredder's scientist did a DNA test which is how I found out about us being siblings and then I found a file on our parents and us.''

Chris was surprised by that information and was glad that he was back with his sister. ''So, what now?''

Caitlin shrugged, ''I don't know. But I know what I have to do. I'm going after the Shredder no matter what the cost.

''Whoa, hold on there sis. I know the guys killed our parents, but wanting revenge is not what we should do.''

''I didn't say you had to come with me, but this is something I feel like I have to do.''

''And what do you hope to gain?''

Caitlin was silent.

''If there is one thing I learned is revenge never achieves anything but more pain. I know he killed our parents, but do you think hurting him will help ease the pain?''

Caitlin sighed. ''I guess not.''

''Great, let's go see the turtles then.''

Caitlin sighed. ''Something tells me their all gonna be happy to see me except for Raph.''

''Don't worry about him, he is just grumpy.''

Caitlin smiled. ''Okay, let's go.''

*…*

Back at the lair, Leo had just gotten back from trying to find Caitlin again. He saw that Raph, Donnie and Mikey were gathered on the couch talking. ''Guys anything?''

Mikey and Donnie shook their heads. Raph sighed, ''told ya it was pointless.''

''Raph why do I have to keep telling you it's not?!'' ''we ain't gonna find her Leo!''

''That's not true!'' ''Yes it is! she's been gone for weeks! were not gonna find her!''

''Found her!'' They look over and see Chris standing next to his sister. Leo stared at her shocked. ''Caitlin!''

''Yeah, Caitlin you remember her Leo. She's my sister who you told me was here with you guys, this whole time.''

''Uh…well Chris you see…''

Chris raises his hand stopping Leo and approaches him. ''I'll let this slide, but next time you lie to me and you're going to wake up without a shell. Oh and if you see April, tell her she is next.''

Leo was so shocked all he could was nod. Chris then turned towards his sister. ''Caitlin, is there something you want to say to Leo?''

Caitlin sighed. ''I'm sorry, I shouldn't have ran away. Happy?'' she said looking at Chris.

''I am, Leo?'' he waited to hear the turtle leader's response.

Caitlin rolled her eyes. ''It's okay Caitlin, just don't do that again you had us worried'' replied Leo.

''Don't worry, she won't since she decided to stay at my place. That reminds me,'' Chris left leaving Caitlin with the turtles.

Caitlin looked down at the ground, not liking how everyone was staring at her. That's when Leo cleared his throat, ''So where were you Caitlin?'' ''Um…I was, around.''

''Where-''

''Look, I'm fine okay Leo?''

Leo sighed. He thought back to the night where they talked on the rooftop. Why was it so hard to talk to her all of a sudden?

But then he remembered something, ''how are you feeling? you never really fully recovered the last time we saw you.'' ''I-I'm okay.'' Donnie looked at her, ''are you sure?'' ''y-yeah.'' Raph scoffed. ''Your'e a really bad liar.'' ''Raph,'' Leo punched his arm ''don't be rude.''

Caitlin sighed. She should've known that she wouldn't be welcomed here. But that's when Mikey spoke up. Mikey smiled at her, ''come on it's okay, you can talk to us. Were friends now.'' Caitlin looked up at him, ''we are?'' ''of course!''

Caitlin was surprised, ''B-but I tried to kill you.'' Mikey walked towards and put a hand around her shoulders. ''Oh, that's all in the past. Your'e on our side now.''

Leo smiled, ''Agreed.'' And Donnie nodded to show his support. Caitlin was speechless. Were they trying to accept her now? after all she had done?

Raph grunted and just threw his hands up in the air and walked off. Caitlin glared after him. ''What's up with him?'' Mikey shrugged, ''just ignore Mr. Grouchy Pants.''

Caitlin laughed. ''So, I see that our guest has returned.'' The turtles and Caitlin looked up seeing Master Splinter. ''H-hi again.'' ''Welcome back child, may I have a word with you?''

''Um, sure.'' She walked past the turtles and followed him into the dojo. When she walked in, she was amazed at how beautiful it was. The moonlight was reflecting through the sewer grate and cast a glow against the gnarled tree in the center of the room.

There was also different weapons hanging on the walls and huge rugs spread across the floor to make it easier for fighting. Splinter walked next to her and lead her to a smaller room which she guessed was his room. He told her to have a seat, and poured her some tea. ''Thank you,'' she taking a sip ''so what is that you wanted to speak to me about?''

Splinter looked at her, before taking a sip of his own tea. ''I wanted to talk to you about the Shredder.'' Caitlin gasped and tried not to break the teacup.

''W-why are you asking?'' ''because I want to share some history with you about him, so you know exactly who your'e dealing with.''

He explained to her how he had once been human and called Hamato Yoshi and that the Shredder and him were once brothers and fought side by side. Until, they both fell in love with the same woman Tang Shen. And she only had eyes for Yoshi. One day, Shredder found them and started calling Yoshi many insulting things, and Yoshi lashed out on him. Soon, him and Tang Shen had a daughter and named her Miwa. That was when tragedy struck. The Shredder had attacked their home setting it ablaze and Yoshi tried to fight against him but it was hopeless. He lost his beloved Tang Shen and his loving daughter that night. And things were never the same.

''I can't believe he would do that, I'm so sorry that had happened to you.'' ''It is alright child.''

Caitlin looked up at him, ''why did you tell me all this?'' ''because Caitlin Chris has told what happened to your family, and we just want to help you. Do not go against the Shredder on your own, we will help you when the time is right.''

Caitlin understood, but still had so many questions racing through her mind. ''I trust you'll be staying with Chris?'' Caitlin nodded. ''Very well, and Caitlin I just want to let you know that you are welcomed here anytime.'' ''Thank you Master Splinter.''

*…*

Back at Shredder's lair, Karai was looking for answers. She was still wondering what had motivated her sister to turn on her and she doubted what Shredder had told her.

She was in Shredder's office looking through looking through his files until she came across a file with Caitlin's name on it.

She opened the file and couldn't believe what she read. Not only did she find out that Caitlin wasn't her sister, but she found out how her parents died.

She didn't care, it didn't change anything Caitlin was still her sister and she was going to find her. And she knew who she had to find first to help her.

She disappeared into the night, running across the rooftops trying to find the turtles. That's when she saw April, Casey and another boy with them who Karai remembered as the boy Caitlin fought before, walking out of the movie theatre.

She then overheard their conversation.

''So, any reason why you guys lied to me about where my sister was at?''

''Were sorry Chris, but Leo didn't want you to be upset and we had no idea where she was'' said April.

''You still should have told me something,'' he then turns towards Casey. ''And you, let me guess April here told you to not say a word to me too?''

''Uh maybe…''

''You disappointed me, bro,'' he turns back towards April. ''So, go make sure Caitlin doesn't leave again. I need to go get her something.''

April nodded, ''okay Chris. What are you getting her?'' ''You will see.'' Chris then took using his super speed. Karai was shocked. She then realized that it was the same guy who fought Caitlin from before and decided to follow him.

*…*

Back with the turtles, Leo, Donnie, Mikey and Caitlin were hanging out watching Tv. ''Hmm I don't think I get it.'' ''Oh come Caitlin,'' said Leo ''this a great show!''

''maybe but..I still don't get it.'' Leo grab be her hand and pulled her down next to him. ''Come on sometimes you have to get closer to the action to really see what's going on.''

Caitlin gave a small smile, before they both realized they were still holding hands and they let go quickly, and Leo blushed a little.

They kept watching the show, and Caitlin was starting to like it. Until Raph walked in a little later. ''Hey Raph,'' Mikey said looking over his shoulder, ''come join us.'' Raph looked over and glared at Caitlin, ''not interested.''

Caitlin fell silent and looked at the ground. Leo stood up, ''Raph can I talk to alone?'' before he could say anything though, he grabbed Raph's arm and dragged him into the kitchen. ''What are you doing?! why are you being so mean to her?''

''In case you forgot Leo, she was raised by the Foot clan. I don't trust her!''

''It doesn't matter Raph she's on our side now!''

''and what if this is all a trap?''

''your'e being ridiculous!''

Meanwhile, Caitlin was standing outside the kitchen hearing everything. And she understood why Raph didn't want her around. She shouldn't have come back.

''Boys! that is enough!'' said Splinter walking into the room, ''Raphael I have had enough of this.''

''But Sensei she's-''

''It does not matter anymore. She has changed Raphael, give her a chance.''

Raph growled in frustration and walked off. Leo sighed. ''Why does he have to be so stubborn Sensei? can't he understand that's she been through so much?''

''I believe he is still having trouble trusting someone who was once our enemy. It will take time and once she shows she can be trusted, then he will let go of his anger towards her.''

''I understand Sensei.'' Caitlin fell silent, back away from the kitchen and walked away.

*…*

Chris was finishing getting a copy of his key for his sister. He then went to get some food, but while waiting Chris felt someone tapping him on the shoulder and turns around. ''Hi.'' He sees it's a girl around his age except she had a jacket, no makeup, jeans, and boots.

''Um hi,'' he replied surprised by the pretty girl talking to him. She gave him a small smile.

''Um what's you name?''

''The name's Alexa.'' She smiled again, ''how about you?''

''C-Chris,'' he clears his throat. ''My name's Chris, it's nice to meet you Alexa.''

''You to. Hey…um, I'm kind of new and it look you were an expert…mind showing me around?''

''Sure.'' He placed the order. Karai smiled to herself, ''This was too easy.''
