A short list of some rewatch gems (Spoilers)
1. When discussing the fence Redfoot Verbal asks "in California?" which could be interpreted as the character keeping up his dim-witted act OR could have been Keyzer getting confirmation of Redfoot's location so he could (off-screen) send "Kobayashi" ahead to find and coerce Redfoot
2. "Kobayashi" checks his watch and has a look of concern before boarding the elevator because he was informed ahead of time about the ambush and its exact time.
3. When Keaton tells Verbal that Edie will handle Keyzer her way, Verbal has a pensive look or maybe that's Keyzer thinking that he has to kill Edie now too.
4. When you see Verbal worried at the beginning of the ship assault that could be Keyzer worried because he has a lot at stake.
