"Karai, listen. There's something you should know. It's about your father! Your real father!! Your real name is Miwa!"
"I'm not interested in anything but you begging for your life!!"
Master Splinter, I tried to tell Karai that you're her father. I thought that if she knew, she would come over to our side.
There is a saying: He who runs his mouth gets a face full of nintako.
They say that in Japan?
They would if you were there. Still, your heart is in the right place. Perhaps it is time she knew the truth.
Maybe you should tell the other guys, sensei.
This is difficult, but it is time you all knew the truth. The child I thought I had lost in the fire, Miwa is Karai - my daughter. Fury became flame, and flame darkened the world with smoke. And in that darkness, Shredder stole Miwa away. I thought she had perished, but she raised by Shredder as his daughter and trained as a deadly Foot assassin.
Wait. This can't be.
Some kind of joke, right, sensei?
Karai's our sister!?
Sensei, she's still our enemy. She was raised by Shredder.
Yeah. How can ever trust her?
[Picks up the black-and-white photograph of his former human self and Tang Shen, with the infant Miwa between them]
There is good in her. I know this. But truth must be told, and it too will be an earthquake.
Karai. Karai, don't do this. Splinter- He's your father. Your true father!"
"Liar! You'd say anything to save him!!"
"No, I swear it!! He's your father- Hamato Yoshi."
"If you won't be silent, I'll silence you."
