A new trailer teases Kiernan Shipka's appearance as Sabrina Spellman from Netflix's The Chilling Adventures of Sabrina in Season 6 of Riverdale.

The popular CW series introduced Sabrina Spellman from Netflix's Chilling Adventures of Sabrina in a new trailer.

Sabrina appears at the end of the trailer, clad in a long, red cloak, with Cheryl Blossom greeting her: "Look at what the black cat dragged in.".

TV confirmed Shipka's appearance in the series earlier this month with a photo of the actor on the set of the CW show, with the caption, "looks like someone is making the road trip from Greendale to Riverdale." Shipka will reprise her role from Chilling Adventures of Sabrina, which ran on Netflix for a total of 36 episodes across two seasons -- split into four parts -- from October 2018 to December 2020.

Sabrina will appear in Riverdale Season 6, Episode 4, "The Witching Hour," wherein Cheryl Blossom (Madelaine Petsch) will perform a dangerous spell that could "mean the difference between life and death for a beloved member of the Blossom family," according to the episode's description, and she will need help from Sabrina Spellman herself in this long-anticipated crossover event.
