Plot hole: The IMIPAK weapon marks its victims and then kills them with a secondary device. But it's inconsistently selective. When Servalan kills the guard with it, Blake and co., marked and standing nearby, are unharmed. But Rashel later warns Travis not to push the button because he and Servalan are marked and would die too. (That the weapon's range is "adjustable" is nowhere mentioned or implied. Servalan doesn't change a thing before she fires it). (00:43:55 - 00:46:30)
Visible crew/equipment: When the clone Blake is asking Coser for the weapon and holding his hand out, the boom mike is visible hanging over his head. (00:36:45)
