Captain Rex: Why, General? Why kill your own men?
General Krell (chuckls): Because I can. Because you fell for it. Because you're inferior.
Captain Rex: But you're a Jedi! How could you?
General Krell: A Jedi? (laughs) I'm no longer naive enough to be a Jedi. A new power is rising, I've foreseen it. The Jedi are going to lose this war, and the Republic will be ripped apart from the inside. In its place is going to rise a new order, and I will rule as part of it.
Captain Rex: You're a Separatist!
General Krell: I serve no one's side, only my own. And soon, my new master.
Captain Rex: You're an agent of Dooku.
General Krell: Not yet, but when I get out of here, I will be. After I've succeeded in driving the Republic from Umbara, the Count will reward my actions and make me his new apprentice.
