Because these shows exist within the same universe, crossovers are inevitable and they've already happened. A Riverdale lead, Josie (Ashleigh Murray), jumped ship and completely swapped shows while a minor Riverdale character made an appearance in Sabrina's second season.
Aside from the thrilling plot twists, the shows' romances are what keep fans hooked. In the newest issue of the Archie Comics, an unexpected relationship is budding and could inspire an epic crossover event in either of the already existing Archie-verse series.
Things also get pretty twisted in the comic book series about Archie and Sabrina when he (SPOILER ALERT!) professes his love for Cheryl Blossom, another Riverdale character.
Not only is a Sabrina and Riverdale crossover happening in the new comic book series, but a Bachelor reference is a prominent plot point. Desperate to discover Archie's new love interest, Betty and Veronica enlist Cheryl to host a Bachelor-esque show in town and cast Archie as the lead role.
In the end, Archie tells Cheryl that he is in love with her, but it seems like a way for him to get the gaggle of girls off his new relationship's trail.
"Archie found himself drafted into a local bachelor contest organized by Cheryl Blossom," the comic book reads. "But orchestrated by Betty and Veronica."
Archie reveals he's actually in love with Cheryl, and she rushes him offstage to discuss the implications of his statement privately.
