Agatha Harkness’ coven is adding members, with reports starting to emerge that Heartstopper’s Joe Locke has signed on to appear in the upcoming Disney+ series Agatha: Coven of Chaos.

Locke will be the third actor confirmed for the WandaVision spinoff, which centers around Kathryn Hahn’s Agatha Harkness. Emma Caulfeld Ford is also attached to reprise her WandaVision character Dottie in the new show, as well. Particular plot details — and the identity of Locke’s character — have not been revealed by Marvel Studios. (Our money’s on Nicholas Scratch for Locke’s character; he’s Agatha’s even-more-evil son, with a wonderfully over-the-top name to prove it.)

Coven of Chaos, which remains unscheduled by Marvel, is the first of two WandaVision spinoffs in the works for Disney+, with news of the project initially breaking late last year. Jac Schaefer, who worked as head writer and executive producer on WandaVision, is serving in the same positions on the series.

News of Locke joining Coven of Chaos, which was first reported by Variety, comes on the heels of reports that Marvel has started pre-production on the second WandaVision spinoff, which is rumored to be titled Vision Quest and centered around Paul Bettany’s Vision.

Meanwhile, Elizabeth Olsen’s Wanda Maximoff is still seemingly dead, after her heel turn in Doctor Strange in the Multiverse of Madness… But how long is that going to last really, given the possibilities?
