Yes, that's a good one. Mace also asks Anakin "are you sure" about Sidious. The Jedi and the Sith's inability to sense each other, at the end of each trilogy repsectively, leads to their downfall. I also find it funny that Yoda says "Only the dark Lord of the Sith knows of our weakness. If informed the senate is, multiply our adversaries will." They have no idea a Sith is leading the Senate, athough come the time of ROTS they think it is someone in the Chancellor's office. Mace later states "The dark side of the force surrounds the Chancellor".
