Have you ever noticed how some shows manage to keep their main characters ridiculously close to chaos without ever putting them face-to-face with it? Stranger Things played around with this dynamic over the years, but especially with one of its most important characters. He was always involved, but never fully immersed in the situations that defined the series’ main threat. The Upside Down has been one of the show’s central settings, and plenty of key characters had already been there before the final season. But if you don’t remember or never really noticed, only one of them hadn’t set foot there all this time. Nine years in, and it wasn’t until the last episode that this “habit” was finally broken.

We’re talking about a character who always stayed on the front lines, but in an indirect way: organizing strategies, leading friends, trying to anticipate the enemy’s moves — just that. But that seems like a deliberate choice from the Duffer Brothers, not a coincidence; it’s smart narrative manipulation. Despite the many complaints from fans about plot holes and other questionable decisions, here the showrunners seem to have been careful with this character’s arc.
Mike Had Never Been in the Upside Down Until Stranger Things Season 5
Out of all the main characters, Mike (Finn Wolfhard) is the emotional and strategic backbone of the gang. But considering he’s been a leader since Season 1, it’s almost ironic to think he went through disappearances, monsters, deaths, and psychological attacks — and still never crossed the dimension that connects all the series’ threats. For some fans, it’s an easy detail to overlook. But the question now is: “Why hadn’t he gone in before?” Since Stranger Things ended, the Duffer Brothers haven’t commented on this, so we’re left to speculate. But even if it wasn’t a deliberate choice, it’s a fascinating coincidence for Mike’s arc, though. And why? Because it makes his first experience feel like something that actually counts.
Mike has never been just another character filling space; as mentioned, he’s always been the group’s moral center, the guy who makes tough calls and keeps everyone together (even though he hadn’t been as active in that role for a while). That alone already makes his first experience in the Upside Down feel especially meaningful. And not every show can build suspense like this and make it feel natural.
But the cool thing for his character development is that this waiting game created a payoff you don’t even realize is there until it finally happens. What does that actually mean? Let’s get into it.
What Makes Mike’s Delay in Entering the Upside Down So Interesting
Having Mike face everything, face-to-face, is about highlighting his courage, testing his leadership, and finally putting all the decisions and responsibilities he’s carried over the seasons to the test. It’s the peak of his evolution as a character and an emotional turning point in the story. After all, the series’ ending revolves around him, and if he hadn’t experienced all of it with the gang, how much weight would his words in the end really have? Even his theory about Eleven (Millie Bobby Brown) wouldn’t land as hard, because he wouldn’t have felt the same loss in her absence. After all, he wouldn’t have fully lived the final battle.
Seeing Mike step through the portal into the Upside Down carries some heavy symbolism. It’s like what he’s always studied, worried about, and talked about finally becomes real in a physical way, not just emotionally. On top of that, it gives the audience a chance to see, almost retrospectively, just how perfectly timed his entrance was — arriving too early wouldn’t have had nearly the same impact.
In the end, whether it was a planned move or just handled as something that naturally made sense (after all, he’s part of the group, and the whole gang is in the final battle), it’s really satisfying to see his arc wrapped up neatly. Five seasons, nine years, and Mike set the ultimate record. But more than just crossing a portal into the Upside Down, it’s seeing one of the show’s biggest characters finally step into the action, proving that leading isn’t just about planning from the sidelines — it’s about being in the middle of the chaos and showing your worth alongside everyone else.
