Continuity mistake: After the sergeant has a parasite bug forced into her, she grabs a syringe kit left on the table by the medic. When she flips it open, there are 7 (maybe 8 at most) syringes in the kit (the last one is broken). A few moments later, private Sandee follows a trail of syringes left on the ground to the sergeant. There are at least 7 syringes on the ground, and 3 others in the sergeant's thigh.
Pvt. Lei Sahara: There're too many of them, Dax.
Captain Dax: You've gotta tell 'em what you saw, Sahara. You gotta tell 'em about the new bug.
Pvt. Lei Sahara: You stay here, you'll die.
Captain Dax: Murderers don't go home.
