One of the most heartwarming moments in the last episode of season four is when the entire Hawkins gang reunites at the Byer's house. Some also travel to Hopper's old cabin in the woods to spruce it up, including new cast member Argyle (Eduardo Franco). When Jonathan and Nancy are talking outside the cabin, Argyle is harvesting mushrooms from the nearby trees. When Vecna's invasion into the real world from the Upside Down suddenly resumes in Hawkins, Joyce, Hopper, Jonathan, Nancy, Mike, Will, and Eleven sense the imposing danger and stand on a hill that overlooks the town, which is already engulfed in dark clouds and flaky particles.
The only character missing from this shot is Argyle, who was definitely present in the scene before but is absent in this dramatic cliffhanger. This is either a major error in continuity, or Argyle's absence could turn out to be significant to "Stranger Things"'s final season.
