Just saw the promo video for the upcoming ep. Looks like Leo is gonna be the one who first doesnt trust Karai. Can't say I blame him, as she did break his heart.

Well, as previously stated, we know that Karai doesn't share her "dad's" thirst for vengeance. She is definitely more level headed than him, as she is willingly to fight with the turtles to save the planet, and she knows Shredder will most likely do the opposite, which she admits in this scene. We also know that Shredder makes an appearance later, so I'm guessing he finds out, and doesn't approve of the truce.

Ironic really, as at the end of the scene, Leo refers to Karai as "Sister". Possibly this is yet another hint sent to us by the writers.
