On Wednesday, Nov. 13, it was announced that Netflix's Stranger Things had wrapped its third season, with some of the cast members, most noticeably Millie Bobby Brown, sharing emotional messages in delivering the news. The season isn't due to premiere until sometime next year, but fans are already speculating on what some of the pictures posted yesterday might mean. In fact, some fans believe this might spell the end for the series in general.

Over on her Instagram, Millie Bobby Brown told fans she was going to "cry all day" over the last day of shooting for the season. Writing individual messages to her co-stars and putting an emphasis on saying goodbye, she led some to believe that either her character Eleven is leaving the show or the show is starting to wrap up earlier than expected.

That's not even mentioning the pictures Brown shared that were captioned "one more time," which undoubtedly give a lot more weight to some of the theories regarding the show's eventual end.

The 15-year-old Finn Wolfhard, who plays Mike Wheeler on the show, also posted a picture of him with a significantly shorter haircut. At first it would appear as though it's a simple post-season haircut now that he no longer has to stick with his signature 'doo on the show for the third season, but it could also be taken as an indication that he's wrapped with the show for good.

This is all just speculation right now, however, and it would be highly unlikely that Netflix would want to call an end to one of their most popular shows only three seasons in. David Harbour, who portrays Jim Hopper on the show, has already explained before that Stranger Things will likely run for one or two more seasons after the third. "We're either going to season four or season five," Harbour told CNET.

The veteran character actor has stated that he already knows how the show will end, but the creative team could always be pulling a fast one on everyone. Even if it does go on for more seasons, there's still a chance Millie Bobby Brown could exit at the end of the third.

Earlier this year it was rumored that the show's creators, the Duffer Brothers, would be leaving the show after season three. However, Netflix quickly refuted the rumors, meaning that even if season four is eventually happening, at least it'll be in good hands.
