Factual error: When Janeway visits Seven as she works to destroy the Omega molecules in the chamber, Seven reports that 11% have been neutralized. They then have a 1 minute, 10 second discussion, and when it's over, Seven states that 18% of the molecules have now been neutralized. Janeway comments, while checking the computer screen, that at the current rate, "this could take hours". Actually, at the current rate, it will take less than 15 minutes.

Continuity: Early in the episode, the Kyrian historical researcher plays a simulation of events aboard Voyager that include Janeway killing a Kyrian and then throwing the rifle to a crewman. Later, he replays the simulation for the Doctor, but subtle details of this 'same simulation' change, most notably the way the female crewman raises her rifle much sooner the first time we see Janeway walk past her, and the difference in the way the male crewman catches Janeway's rifle.
