mace looks like he's struggling with some nagging feeling in some of the earlier scenes in aotc....i think they definitely sense something....i tend to think one of palpatine's powers is to cloud people's minds at will, it ties in with his other major power, which is the power of persuasion (convincing jar jar to make the right moves in the senate, anakin to turn from the jedi order etc.).....it's an intense dark side version of the jedi mind trick (these aren't the droids we're looking for).....when you think about it, up until now all we've really seen him do is hit vader with a bit of lightning when he was already incapacitated....he is supposed to be so powerful that even yoda is somewhat in awe, yet from what we know so far, he only possesses this one power.....so it makes sense for it to be an almost unbelievably strong talent that he wields....
but then again...yoda makes the EXACT same face i make, when im in an elevator with someone else...and they fart...and i KNOW they farted...but they just stand there and act as if the fart just materialized out of thin air...so i give them that look like "yeah, your not fooling me pal"
so maybe queeq is right? 😆
