As the old saying goes, time flies when your favorite show stages a significant, season-ending, narrative-altering time jump.

TVLine has learned that the producers of an established series are toying with the idea of ending the current season with a massive timeline shift. According to sources, the length of the time jump being considered is in the neighborhood of five years. If the trigger ultimately gets pulled on the flash-forward twist, it would have enormous implications for a number of the show’s current storylines/characters ahead of next season.
