When Seven enters the astrometrics lab and first learns of the "wormhole," she states that the "wormhole" is only 300 million kilometers away. Later on when she first contacts Qatai, she says that Voyager is on an intercept course 3.4 light-years from his position. Also, Tom says that they are still several hours away from the "wormhole," which is in line with the distance Seven states while talking to Qatai, as Voyager would be able to cover a distance of 300 million kilometers at full impulse in a matter of minutes as full impulse is 1/4th the speed of light.
When Voyager enters the 'wormhole,' Tuvok and a couple security officers are in engineering when they and everyone else become unconscious, but when Naomi seeks Seven in engineering, Tuvok and the security officers are in a corridor.
Miss Wildman and Seven of Nine pass through an area of the U.S.S. Voyager with many windows, the orientation of which indicating that they are on the dorsal section of the ship. There is no corresponding section of windows on the dorsal exterior of the U.S.S. Voyager.
Seven tells Qatai that Voyager is 3.4 light years away from him; however, near the beginning of the story, Voyager was 300 million km away, which is only 16.67 light-*minutes* away. The distance Seven states is 32 quadrillion kilometers.
When Seven is dismissed from Astrometrics she had a dark lipstick on her lips. However when she arrives in the cargo bay and discovered Naomi Wildman she has a lighter lipstick on. There's no way she'd have enough time to change her lipstick color in the time she left Astrometrics to the time she arrived in the cargo bay.
Ensign Paris is taking over for the Doctor in Sick Bay. However only a few short frames after Seven leaves Sick Bay later he is shown to be on the bridge piloting Voyager to the wormhole. There's no way he could have gone from deck 5 to the bridge in that short amount of time.
