Earlier today, we reported that Roberto Aguirre-Sacasa was one of the folks associated with Chilling Adventures of Sabrina who took to social media soon after it was announced Netflix was ending the series with the upcoming eight-episode Part 4 (set to air later this year). In his post, the showrunner and executive producer confirmed the news but also reminded fans that there was still a ton of story to tell before the final spell is cast. Well, it appears now that CAOS had a ton more story to tell beyond Part 4, and that Part 5 would've had the one thing viewers have been asking for the most: a full-on, legit crossover with Riverdale. Taking to social media Thursday evening, Aguirre-Sacasa posted an illustrated image of the gang from Riverdale and the CAOS crew with the teaser line, "The Witches of 'Riverdale' Are Coming…". And just in case you were wondering how it was going to be, well, let's just say he wasn't subtle when he writes, "'Witch War' would've been AMAZING." A consolation? Looks like the storyline will be making its way to the comics world.
Fans of CAOS who've wrapped up Part 3 already know that the seeds of a Riverdale crossover were already bearing fruit. Here's a look at two huge Riverdale/CAOS crossover threads from the previous season – as well as The CW series' "response" with a CAOS character who's already made the leap:
"Chapter Twenty-Three: Heavy is the Crown"
(Director: Rob Seidenglanz/ Writer: Oahn Ly)
● First, let's take a look at that sign (above) that Sabrina and Ambrose (Chance Perdomo) pass as they look to retrieve the crown of Herod. "Murder Capital of the World" is a clear reference to the town of Riverdale's infamous nickname, and the "JJ Wuz Here" is clearly cornball enough to be Jughead Jones (Cole Sprouse).
● So Sabrina and Ambrose actually enter Riverdale – well, at least the wooded area just inside the border so that counts… right? As for the artifact they're looking to retrieve? Previously in the possession of a Benjamin Blossom – a name shared by a certain Cheryl (Madelaine Petsch). Considering Cheryl's supernatural-tinged lineage – and the fact that the crown was retrieved from a maple tree – it's safe to assume that Greendale isn't the only town whose foundations are tainted by the supernatural.
"Chapter Twenty-Six: All of Them Witches"
(Director: Michael Goi / Writer: Joshua Conkel)
● When Circe hits Hilda (Lucy Davis) with a spell that brings out her inner-spider in ways none of us (especially Hilda) wanted, she visits Dr. Cee (Alessandro Juliani). Hungry, she asks him to run out to a diner in Riverdale that has "the juiciest hamburgers and thickets milkshakes" – clearly, a reference to Pop's Chock'Lit Shoppe.
● To drive home the point even further, Hilda's spider cravings create an appetizer in the form of a Southside Serpents member (the Sharks/Jets-like gang from Riverdale) – who picked a very bad time to need a new book.
"Riverdale" season 4, episode 10 "Chapter Sixty-Seven: Varsity Blues"
(Director: Roxanne Benjamin / Writer: Aaron Allen)
● Meanwhile… Betty's (Lili Reinhart) investigating accusations of Stonewall Prep football players intentionally hurting opposing players, so she interviews a number of players from other schools for more info. One of those players? Baxter High Ravens' Billy (Ty Wood), Theo's (Lachlan Watson) ex-bully (after Hilda got her hands on him), and a member of a team known to be sports rivals of the Riverdale Bulldogs.
