Count Dooku and General Grievous in “Unfinished Business”

Count Dooku

I can sense him, Grievous. That creature, Savage Opress, is growing stronger and stronger as each day passes.

General Grievous

[coughing] You consider him a threat?

Count Dooku

He is a threat to all of us, even the Jedi. With the Nightsisters eradicated, there's no one left to control him. Something is rising, something sinister.
