At the end of VOY:Year of Hell Part 2, you see Annorax with his wife and he is working on Temporal Incursion Calculations. Does this imply that a significant portion of the Delta Quadrant would be stuck in a sort of temporal loop?
To explain this, Annorax designs and builds his ship and things go to hell because he can never restore the Krenim Imperium as well as Kyana Prime. Eventually, someone stops him and as Voyager did finds a way to reverse what he did and then the loop starts again because Annorax is back on Kyana Prime, working on his temporal incursion calculations.
Following this, it means that Voyager saved themselves this time but doomed everyone in the Delta Quadrant because the only way to stop the threat of Annorax is to kill him or destroy the ship without generating a temporal incursion that resets everything back to 0. Think the TNG episode Cause and Effect. Not the same I know as the Temporal Causality Loop from that episode was due to an anomaly in space.
