Roberto shared a statement with TV Line about the show's termination:
Working on Chilling Adventures of Sabrina has been an incredible honor from Day One. The cast, beginning with Kiernan [Shipka] as everyone’s favorite teen witch, has been an absolute joy. I am beyond thankful to the crew, writers, editors, assistants, and everyone for pouring so much love into this dark dream of a show. I’m also grateful to our partners at Netflix, Warner Bros., Berlanti Television and Archie Comics for letting us tell the story we wanted to tell, the way we wanted to tell it. We can’t wait for everyone to see Part Four.
