Shredder and Karai in “Unfinished Business”

So, Daughter. You not only disobey my orders in my absence, your petty scheme failed miserably.

It was those stupid Footbots! They couldn't keep up with the Turtles! But here's the good news- the Kraang have been upgrading them.

Hear me, Karai. You will not have anymore dealings with the Kraang until I return. Do not defy me again! The consequences would be...unfortunate.

Understood, Father.
