Olivia Holt
The series' second season told an entirely new story with a completely different cast, but season three brings back a key player from the original.
According to Variety, Holt will not only reprise her role in the series but also serve as executive producer, along with Cori Uchida and Adam Lash, who will also serve as showrunners. The content of the new season has not yet been announced.
In season one, the story revolved around the disappearance of Kate Wallis, an event central to the series' mysterious and compelling premise.
