Warning: Spoilers for Stranger Things season 4, volume 1!
Stranger Things star David Harbour explains that the details revealed in season 4, volume 1 concerning Hopper’s tragic backstory were almost always part of the show's plan. When Matt and Ross Duffer’s nostalgia-laced series premiered on Netflix in 2016, audiences were introduced to James “Jim” Hopper, Hawkins’ (borderline) alcoholic police chief who, despite being pretty rough around the edges, is a pretty decent guy. Stranger Things season 1 flashbacks elaborate on the chief’s depression, revealing the death of his 7-year-old daughter Sara due to an unspecified illness and his subsequent divorce.
In the fight against the Upside Down’s Demogorgons and Mind Flayer, Hopper gains a new sense of purpose thanks to the relationship with Eleven, his surrogate daughter/telepathic superhero, and Joyce Byers (among others). After seemingly sacrificing himself to save his loved ones, Stranger Things season 4 picks up with Hopper in a snowy Russian prison waiting to be rescued as he and his fellow prisoners prepare to combat a Demogorgon. “Chapter Five: The Nina Project” finds Hopper at his lowest point, where he reveals to Dimitri (and the audience) how, in Vietnam, his unit unknowingly mixed the chemicals for Agent Orange.
