Leonardo and Splinter in “Unfinished Business”

I'm sorry to bother you, Master Splinter. I need to ask you some questions- about Karai.

It is late, Leonardo. These questions will have to wait for another time.

She said you took her mother away from her. I know it's not true, right?

No. It is not true. But the truth is just as difficult.

Please, sensei, tell me. Trust me.

Karai... is my daughter.
