Author's note: So what did you think about chapter one? By the way the flashback in the last chapter takes place in the episode "Turtles in Time." The only difference is I added the part where Miwa has a twin. Also, I made an error in the last chapter. It was supposed to be a flashback and chapter one. I forgot to put chapter one at the top of the page. Sorry for the confusion! Enjoy the chapter!

Chapter two: The secret

*16 years later in New York*

"Happy Birthday Rai!" Leonardo said to his adoptive sister.

"I have something for you my daughter." Master Splinter said.

Splinter hands her a katana sword similar to Leo's.

"Thank you father." Rai thanks her father.

"Nice sword." Donatello says.

"Now it's time to partaaaaaaa! Because it's your sweet sixteen!" Michelangelo says.

"Whatever you say Mikey." Laughs Raphael.

The four turtles go to the dojo.

The past few months Rai and the turtles have battled the Kraang, foot soldiers, Shredder's henchmen, and his top kunoichi, Karai. As time has gone by Rai has been more curious about Karai. Ever since they meet her, Karai has a rivalry between her. She is evenly matched with Rai. Leonardo is evenly matched with her too and has a crush on her. Rai laughs at her brother for his crush because she is in the foot clan and he is leader.

"Father."

"What is it Rai."

"I have some questions about Karai."

"Rai go party with your brothers.

They are waiting on you." Master Splinter says.

Rai sighs. "They can wait. "

"Father."

"Please."

"Tell me." Rai urges.

"Karai is my daughter." Splinter lets out.

"WHAT!"

"Which means….she…is…my…..sister."

"Yes." Answers Splinter.

"Listen Rai I would have told you but I thought she (Miwa) had perished in the fire but the Shredder kidnapped her and raised her as his daughter. And with your mother gone I wanted you to be happy. So I thought by not telling you would be the best. "Splinter explained.

"I understand father."

"Do my brothers know?" Asked Rai.

"Only Leonardo. He asked weeks ago."

"He was curious like you."

"I think it is time you told the other guys." Rai suggests.

"Yes my daughter it is."
