The Stranger Things play writer Kate Trefry says that the events of The First Shadow will be "integral" to the Netflix show's final season.
"There are referential sequences and imagery and callbacks and flashbacks to the events of the play in Stranger Things season 5 that will still make sense to you if you don’t see the play, but you’ll have a deeper understanding of them if you do," Trefry tells SFX magazine in the new issue, which features David Tennant as Doctor Who on the cover. "It’s in conversation with the seasons prior and the season to come," Trefry says, "It really informs everything that you have seen and will see."
