Teenage Mutant Ninja Turtles, Season 1

Splinter:
You were not fully prepared for what was up there. I trained you to fight as individuals, not as a team. And as your teacher, your father, the responsibility for that is mine. Perhaps in another year we can try again.

Donnie:
A another year!? Has everybody forgotten that people were kidnapped!? They don't have a year! Sensei, we have to do something now! You weren't there, Sensei. You didn’t see the way that girl looked into my eyes. She was scared and she's counting on me- I mean us- to save her.

[Splinters turns to stare at the black-and-white picture of himself, his wife Tang Shen, and their infant daughter Miwa]

Splinter:
Yes. You must save her.

Leo:
I agree, Sensei, but in that fight we weren't actually a well-oiled machine.

Mikey:
Like that robot with the brain thingy.

Raph:
Give it a rest.
