Leo, Karai and others in “Unfinished Business”

Karai, I'm so sorry.

There's nothing to be sorry about, Leo. I just want to thank you for finishing what no one else could.

You did it, brother! You ended the Shredder!

Whoa, Raph. Don't squeeze me so hard, Raph. I'm still recovering.

So, what are gonna do next?

Oh, I'm sure they'll be plenty of enemies to take Shredder's place.

Tiger Claw is still out there. The Foot clan isn't out of the game yet, dudes.

Whatever evil emerges, we'll be ready... 'casue we're awesome.

That's right, Mikey, and we'll do it together. Right, Sensei?
