The Shredder was sure that his daughter's student would have finished off the turtles by now. But, what if she hadn't?

Soon enough, Shin was now going out on patrols with her father and uncles. Leo said, "Honey, if I had raised you, tonight would be the night when you can finally come on your first patrol with me and your uncles. I know you had been wanting to come so bad when you were little. But you are old enough to keep up with us and you do have self defenses now. Let's go."

"I'm coming Dad." Shin said happily. Mike, Don, and Raph tagged along too.

Out on the rooftops, aside from looking for trouble, Shin and the boys raced across rooftops, practiced some ninja moves. Even playing games. So, her dad and uncles did play games while they were out. They were a lot more serious at home, but did humor their younger children.

In a way, the patrols did unify that the turtles were still close friends with each other despite having families now. But now, Leo's daughter was going to start going with them more often.

But out on this night, so were the Foot ninjas. Through night vision binoculars, they were seeing the turtles running over rooftops. Tang Shin aka. Hanoe Lin to them, was with the male turtles. Why hadn't she finished them off? That was her job of why she had been sent to infiltrate their family.

The Foot would get to the bottom of it.

Back at Foot headquarters, there was a mad shout. "WHAT!" The Shredder yelled.

"She hasn't killed the turtles Master." A ninja was saying. "We saw her out with all four of them tonight."

"If she thinks she is betraying me, she will die too!" Shredder growled.

"I think the turtles got to her. And she is one of their kind."

"They must be destroyed! I will do it myself. Prepare your warriors. Tonight is the end for the turtles!" Shredder ordered.

The ninja bowed his head and took off.

The Shredder had had enough stalling. He would find out why Hanoe Lin had not finished off the turtles like she had said she would.

Topside, with the turtles, Shin was having the time of her life. She loved feeling the wind whip over her skin and blow her mask tails in the wind. She didn't have hair like a human girl, but her mask would do like hair. She loved being able to show off her athletic side, to show what she could do as she moved.

The boys were impressed. If she wasn't Leo's daughter, they would all probably have feelings for her.

Soon, they reached midtown. All 5 of them stopped for a breather. "When can we get pizza?" Mikey moaned. "I'm hungry."

"Can it, Mikey." Raph said.

"You're always hungry, Uncle Mikey." Shin said.

"I just love pizza." Mikey said.

"We know." Don added.

"I don't think we're going to find anything tonight guys. Let's head home." Leo said.

"Thanks for letting me come Dad." Shin said.

"It was time." Leo said.

But as they were about to take to jump the next roof, several ninjas came out of nowhere.

"Great. The Foot!" Leo growled.

All five turtles got into battle stances. Then the Shredder showed up. He walked to the front.

"Hanoe Lin! You were supposed to finish off these turtles! Why didn't you do it?" Shredder demanded.

The boys looked at her. Shin had some fear in her eyes, but she was going to speak with confidence. But her dad spoke for her.

"She is not yours to command Shredder! She is my daughter! You stole her from me all those years ago! And we know all about your plan to want to kill us!" Leo said angrily.

"She told us everything Shredder!" Don said next.

But then, Shin had to speak up, "Guys please. Let me talk for myself."

The guys looked at her.

"Master Saki. The way you had these turtles pictured is all wrong. They are not evil at all. They have shown me ways that I have never known being raised by Mistress Karai. They have shown me a new way. From now on, I am Tang Shin! You changed my name when I was young! I belong with my real father!" Tang Shin spoke calmly, happily, and with confidence. "I will never again serve you or the Foot clan!"

"Then, so be it Turtle girl! You will die along with them! Attack!" Shredder ordered.

The ninjas attacked.

Don, Leo, Mike, Raph, and Shin were all holding their weapons and now began the defense fight against the Foot.

Leo had been proud of Tang Shin for what she had chosen and said to the Shredder. Choosing him and his family over the evil Foot.

Shin was good at battling the ninjas, as most of them fought like Karai. Her dad and uncles sometimes did have falls from the ninjas, but Shin knew the battle moves well.

Most of the Foot clan was here fighting. But the turtles never faltered.

Eventually, the ninjas were not having the best of luck, and Shredder took over. He beat and knocked the boys over by a wall. Shin was the last one standing. Suddenly, they all froze. Then she heard her former master's voice. She looked.

"Watch closely Tang Shin! As I finish off your family!" Shredder said.

Shin was watching with fear in her eyes. No! Not her father!

"No! Don't kill them!"

"And why not? They are my enemies."

"Fight me Saki. If I win, you let them go. If I lose, you can take me." Shin said.

"No, Tang Shin!" Leo cried out.

"I'm sorry Dad. I have to." Shin said. "My honor demands this."

"If he should be fighting anyone, it's me, Shin. Shredder owes me for taking my daughter away from me for 15 years!" Leo said angrily.

"Ok. But if the Shredder will let you." Shin said.

"Come on Shredder. You've always wanted to beat me." Leo was trying to encourage Shredder to fight him in his daughter's place.

"Fine. But only you Leonardo!" Shredder gave in.

The ninjas released Leo's arms and he kicked the ninjas who had his swords. He got his swords back. "I'm ready Shredder!" Leo said.

The Shredder attacked. Leo came at him. Swords ready for anything.

Shin and her uncles hoped Leo would be okay.

Leo dodged the worst of Shredder's blows. But he used his swords to protect himself. And when it came down to fancy moves, Leo used some of the moves that he had learned from his own daughter. Karai had trained her, and now, he was using Karai's methods against the Shredder.

In the end, Leo had managed to beat the Shredder by sending him over the edge of the building. He was defeated. Then, he turned to the ninjas. "BOO!"

That got the ninjas to release his family and retreat. Their master had lost the dual. So they left the scene.

Shin came up to her father and gave him a hug. He put his arms around her.

"I wasn't going to let him take you from me again, Shin. I have missed most of your life. He owed me." Leo said.

"I know that now Daddy." Shin said. "But I didn't want him to hurt you either. I'm young and I can move fast."

"I know. But it is also my job as your father to protect you too." Leo said. "Let's go home."

"I agree there, Bro." Raph said.

"Home never sounded so good." Don added.

The turtles headed home. But from now on, even though Tang Shin had been raised in the ways of the Foot clan, and taught by them, she was now forever their enemy. She was back with her real and true family. And she wouldn't trade it for anything in the world. She and her dad had so many years to catch up on.

Shin, her dad Leo, and her uncles Don, Mikey, and Raph would forever to continue to fight the Foot or any other baddies out there, and one day, Shin's brothers and cousins would one day join the battle too.

Leonardo was more proud of his daughter than ever before. She was a true ninja turtle now!

The End.
