Stranger Things Season 5 has been confirmed to be the popular show’s last and is currently in production.
Matthew Modine’s Dr. Martin Brenner or Papa has been an important character in the overarching narrative of Stranger Things, especially due to his connection to Millie Bobby Brown’s Eleven / Jane Hopper (“El”).
One of the most prominent among them surrounds the potential return of a supposedly dead character.
In Season 4, he has one more interaction with Eleven before she leaves, and he dies alone in the desert of Nevada.
