As you may or may not know, Riverdale showrunner Roberto Aguirre-Sacasa is also the creator of Afterlife With Archie, a popular comic series that sees the Archie gang battling a zombie apocalypse.
Sabrina Spellman, the teenage witch, will appear in the final episode of Season 1 (sadly not played by Melissa Joan Hart).
There could be more to Jason Blossom's death than meets the eye.
The twincesty vibe between Jason and Cheryl in Riverdale is straight out of Afterlife. Maybe they're the key to the zombification of the show?
