The Riverdale season 6 episode 19 trailer reveals the first look at Kiernan Shipka's Sabrina Spellman return from Chilling Adventures of Sabrina. After years of hoping for crossovers, Riverdale and Chilling Adventures of Sabrina have finally begun to interact with each other as shows. A year after being cancelled on Netflix, Shikpa came over to The CW as the beloved teenage witch at the start of Riverdale season 6. However, it came with a twist, as she appeared as an alternative version of Sabrina in the Rivervale 5-part event.

Despite having been set in a fairly grounded reality, Riverdale season 6 took on the multiverse concept by exploring the Rivervale universe. In this realm, Sabrina came to Cheryl Blossom for a transference spell. Despite having a short appearance, it left fans wanting more, especially with Sabrina's large role in the Archie Comics universe. It didn't take long until the team behind Riverdale revealed that Shipka would be coming back in season 6 for one additional episode, and will play a crucial role. With Riverdale having introduced witches, Shipka's Sabrina return is set to expand that even further.

Following the events of Riverdale season 6 episode 18, titled "Biblical," The CW (via TV Promos) ran a trailer for episode 19, which airs next week. Appropriately titled "The Witches of Riverdale," Shipka's Sabrina arrives following Percival Pickens causing several firstborns to die during Toni Topaz and Fangs Fogarty's wedding.

Unlike her version in the Rivervale event, Shipka's Sabrina is arriving thanks to one of the newer characters in season 6. Following the end of Riverdale season 6 episode 18, Heather tells Cheryl and the gang that she knows of a powerful necromancer, who is also a witch like herself. When asked what her name is, Heather reveals it as none other than Sabrina Spellman. "The Witch of Riverdale," was directed by Alex Pillai, while Chrissy Marron and Chilling Adventures of Sabrina and Riverdale showrunner Roberto Aguirre-Sacasa wrote it.

It will be intriguing to see how this Sabrina compares to the version Shipka played in Rivervale. Based on the Riverdale season 6 episode 19 trailer, it seems like this may be loosely based on the cancelled storyline that was going to happen in Chilling Adventures of Sabrina season 5. Had Netflix not cancelled the Archie Comics drama, Sabrina and Greendale gang would have crossed paths with Riverdale, seeing Cheryl, Betty, Veronica, Archie, and Jughead as witches. So while not a direct take on it, this is the closest Chilling Adventure of Sabrina will get to doing that storyline in live-action with Riverdale. Hopefully, following Sabrina's return in Riverdale season 6, this will also set up at least one more appearance in the series-ending Riverdale season 7, which will air in 2023.
