Star Wars: The Clone Wars, Season 7

[Ahsoka frees Maul from captivity]

Maul:
You survived.

Ahsoka:
[holds her lightsaber to his throat] Is this your doing? Choose your words carefully.

Maul:
No, it was not my doing. I do not know what has occurred, but surely you have felt it; the voices crying out, the death.

Ahsoka:
The clones turned against me, even Rex. I don't know why, they just suddenly weren't themselves.

Maul:
[laughs madly] Brilliant. Brilliant! [chuckles] I was not privy to my master's plan, but now, now I see it. He turned the Jedi's own army against them.
