I've been thinking about how the show will end, as many probably have. So, just for fun, I wanted to pose 4 options and see which one people would hate most. No, I'm not saying all of these hold any kind of water, I know option 3 would cause an absolute riot haha It's just meant to be lighthearted and fun to discuss.

Option 1: in S3E8: The Battle of Starcourt, in Hopper's heart to heart speech, he says, "To turn back the clock. To make things go back to how they were. But I know that's naive. It's just... not how life works. It's moving. Always moving whether you like it or not." Time has obviously been a big theme. In the wake of destruction in Hawkins, in the midst of battle, maybe some of her friends have lost their fight, El remembers that part of the speech. She decides to turn back the clock somehow. Thus erasing everything that has happened, going back in time and defeating Vecna before Will ever went missing. She loses everything and everyone but she knows the people she loves are safe. If I'm remembering correctly, Mr. Clarke did say the flea could move backwards and forwards. Maybe she can too. That could also explain so many Back to the Future references.

Option 2: At the end, it cuts to a table of friends playing D&D, their mage, Jane, having just crit hit the final boss. It was all just an epic campaign.

Option 3: Fully go Lost Boys style. Mr. Clarke comes in at the last, dire moment, saves the day, lifts his eye goggles and says, "one thing I hate about Hawkins...all the damn Demogorgons." The screen fades on the shocked, confused faces of the kids. This one definitely would enrage so many haha Could also be Ted instead of Mr. Clarke, take your pick.

Option 4: They're victorious in slamming the door on the Upside Down for good. It cuts to years later, in a child's room. A man is telling a story about time travel and alternate dimensions to a little kid. The kid looks skeptical but intrigued. A woman appears, saying it's time for bed. Placing her arm on her husband's shoulder, you can clearly see "011" tattooed. The child says, "mommy, other worlds don't exist, right? Daddy's just being silly....right?" Mike and El look at each other and smile. "Well," she says, "stranger things have happened." Cut to black. Roll credits.
