The epic series finale of Netflix’s Stranger Things, “The Rightside Up,” which premiered on New Year’s Eve and clocked in at over two hours, delivered closure to nearly a decade of mysteries — including the long-debated power dynamic between Vecna (Jamie Campbell Bower) and the Mind Flayer.

For years, viewers speculated wildly: Was Vecna the mastermind shaping the Mind Flayer into his spider-like image after being banished to the Upside Down? Or was the shadowy entity from the Abyss the true overlord, manipulating Henry Creel from childhood? The Season 5 finale, combined with clarifications from creators Matt and Ross Duffer, paints a nuanced picture — one of initial influence evolving into a deliberate, symbiotic union.

The revelation unfolds deep in the Abyss, the Mind Flayer’s chaotic home dimension beyond the Upside Down wormhole. As the Hawkins crew launches their ambush, Eleven (Millie Bobby Brown) and allies confront Vecna within the creature’s massive physical form — a Godzilla-sized spider with Vecna embedded in its chest, connected by tendrils.

A pivotal flashback revisits young Henry’s traumatic memory: In 1959, after killing a scientist, eight-year-old Henry opens a briefcase containing a glowing red rock composed of Mind Flayer particles. Touching it infects him, granting powers while linking him to the entity. “Come find me,” it beckons, as the dying scientist warns it will “consume” him.

This scene, teased in prior seasons and expanded in the stage play Stranger Things: The First Shadow, confirms the Mind Flayer initiated contact early, shaping Henry’s worldview. Yet, the finale emphasizes choice over coercion.

During the climax, Will Byers (Noah Schnapp), drawing from his own Season 2 possession, urges Vecna to resist: “Fight it. You’re being used.” Vecna rejects the plea outright. “I never control it,” he retorts. “Don’t you see, William? I could have resisted it, but I chose to join it. It needs me. And I need it. We are one.”

Jamie Campbell Bower, in a Netflix Tudum interview, elaborated on the mindset: Henry views the partnership as mutual empowerment, aligning with his hatred of humanity’s “cruelty.” The Duffer Brothers echoed this in post-finale discussions with Variety and The Wrap, noting they considered a “Darth Vader-style” redemption where Vecna turns on the Mind Flayer but ultimately rejected it. “He embraces the evil,” Ross Duffer said. “That’s what makes him irredeemable.”

The battle sequence underscores their intertwined fate. As Steve (Joe Keery), Nancy (Natalia Dyer), Robin (Maya Hawke), Dustin (Gaten Matarazzo), Jonathan (Charlie Heaton), and Joyce (Winona Ryder) torch the Mind Flayer’s limbs with flamethrowers and explosives, Vecna weakens — proving the two-way connection. Eleven impales him on a spire, severing tendrils, causing the Flayer’s heart to shrivel. Joyce delivers the killing blow, decapitating Vecna with an axe and iconic line: “You fucked with the wrong family.”

Both entities die, portals collapse via a timed bomb (set to Prince’s Purple Rain), and the Upside Down bridge implodes. Yet, ambiguity lingers: Mind Flayer particles aren’t explicitly destroyed, and the red rock’s origins remain teased for the upcoming live-action spinoff.

Fan theories pre-finale leaned heavily toward Mind Flayer dominance, fueled by The First Shadow‘s depiction of it hovering over young Henry. Post-premiere reactions split: Some hailed the “we are one” reveal as satisfying symmetry — Vecna shaped the Flayer’s form (spider-inspired from his black widow fascination), while it amplified his darkness. Others argued the early infection undermines free will, making Vecna a “puppet” despite his claims.

Critics from outlets like Screen Rant and Nerdist praised the resolution for avoiding oversimplification. “It’s not puppetry; it’s merger,” one analysis noted. The Duffer Brothers, in Tudum, left slight interpretive room: Was Henry’s “choice” truly free, or forever tainted by youthful corruption? They prioritized thematic closure — embracing trauma versus succumbing to it — over definitive hierarchy.

This dynamic retroactively reframes earlier seasons. Season 4 suggested Vecna molded particle clouds into the Mind Flayer post-banishment; Season 5 adjusts to pre-existing infection, with Henry later influencing its manifestations. The hive mind, controlling Demogorgons and others, flows bidirectionally.

The finale’s emotional core shines in ensemble teamwork: No solo hero slays the beasts. Will’s powers distract Vecna; group attacks fell the Flayer. An extended epilogue — D&D game, tearful goodbyes — affirms growth, with portals sealed and survivors moving on.

Lingering threads, like the rock’s broader mythology, fuel spinoff buzz. Matt Duffer confirmed: “The spinoff delves into that… but it’s a completely different mythology.” No deep Mind Flayer dive, signaling closure for the Hawkins saga.

Stranger Things ends as a cultural titan: Blending ’80s nostalgia, horror, and heart, it amassed billions in viewership and merch. Seasons 1-5 stream on Netflix, with animated Tales From ’85 and live-action spinoff ahead.
