Season 2, Episode 4: "Will the Wise":
An ailing Will opens up to Joyce with
disturbing results. While Hopper digs for
the truth, Eleven unearths a surprising discovery.
This episode is important for setting-up the emotional and psychological impact of the Upside Down on Will.

Season 2, Episode 6: "The Spy":

Will’s connection to a shadowy evil grows
stronger but no one’s quite sure how
to stop it. Elsewhere, Dustin and Steve
forge an unlikely bond. Considered by
the brothers to be one of the most important
episodes, this installment shows Will
acting as a "spy" for the Mind Flayer
and deepens the show's mythology.

Season 3, Episode 7: "The Bite": Where
Robin Comes-Out to Harrington as Lesbian,
#NewCoke in Supermarket and Eleven is Injured
Fighting #TheMindFlayer!

Season 3, Episode 8: "The Battle
for Starcourt Mall" (S8 Finale)

Season 4, Episode 7: "The Massacre at Hawkins Lab": As Hopper braces to battle a monster, Dustin dissects Vecna’s motives and decodes a message from beyond. El
finds strength in a distant memory.

This episode reveals significant
details about the origins of Vecna
and the Upside Down's history.

Season 4, Episode 9: "The Piggyback": With selfless hearts and a clash of metal, heroes fight from every corner of the battlefield to save Hawkins and the world itself. The season-4 finale provides the most direct setup for the final season's events and conclusions.

“Season 2 is when we really started to
build out the mythology and started to dive into everything, and how this was going to be an ongoing [series]. That’s where we started to really plant the seeds for the mythology, and I think probably that’s why that is as relevant as it is,” Matt tells THR. “Season 4 is also highly relevant — ‘Massacre at Hawkins Lab’ is a good one.”

Ross adds, Season 2 unveils some of the Upside Down mythology and starts giving some answers, and, of course, all the stuff with Henry and Eleven continues to resonate throughout Season 5.
Those are some good ones to revisit.”
