Which reminds me... why Vader walks all the time..somewhere to nowhere.
I have ideas placing him to be more static (aka ESB like) to more strategic and dramatic places. have him to a pre meditation chamber?
Have him watching/meditating while watching the TIE patrols out of a big window?
Also its like he is indeed under tarkin's leash because where ever is tarkin Vader is there too.
