But that's not the only casting news that Netflix dropped. The streaming platform also shared that Priah Ferguson, aka Lucas' scene-stealing little sister, Erica, is returning to the show as a recurring character.
From her updated character description, expect the 11-year-old actress -- who has also appeared on FX's Atlanta-- to have an expanded role and bring along some new friends on a "wild mission to save Hawkins from a dangerous and unexpected new threat."
"Erica is coming back to roast us all — and she's bringing 'an army of friends!'" Netflix tweeted.
