Headscratchers / Star Trek Voyager S 5 E 23 Relativity

• Why is Seven of Nine able to see the weapon when Voyager is in dry dock? We know that the weapon will be installed by Capt. Braxton two years later when the ship is under attack by the Kazon but not earlier.
  • It seems to be implied that somehow the weapon out of temporal phase will "always" be present on the ship after it's planted from the building of Voyager to its destruction, except in the short instance where it's shortly before the time when the saboteur places the weapon in its location. So in this instance of the Timey-Wimey Ball, you can go to any time in Voyager's existence and view the weapon (if you're a Borg drone or a former drone with a still working visual implant) being there, but during the attack on Voyager by the Kazon is the only time it isn't there because it's "just about" to be placed there.
