Stranger Things releases next year on Netflix, and with it come new cast members and characters. Dacre Montgomery, the Red Ranger in next year’s Power Rangers, has joined the cast, alongside Sadie Sink who played Suzanne Ballard in television series American Odyssey.

Sink will play a tomboy named Max with a “complicated history and is generally suspicious of those around her.” And Montgomery has been cast as her “hyper-confident and edgy” older brother Billy, who drives a Camaro and will probably give Steve a run for his money. Sink’s character is probably the “mad” one referred to in one of the new episode titles, and it’s possible her brother’s temperament will make him “The Storm” or “The Lost Brother.”
