All three parts of Sabrina have seen the teenage witch go up against (and ultimately defeat) some of the most powerful cosmic forces imaginable--even the literal devil, who turned out to secretly be Sabrina's birth father--but the finale is primed to make the stakes even higher. The Old Gods, or the "Eldritch Terrors," are headed for Greendale and the crew is going to have to figure out a way to stop them from they destroy absolutely everything. There's just one catch: No one is quite sure how you're supposed to kill a god.

M Downey breaks down how Part 3 ended, what Part 4 is about, the returning cast of characters, and the drama ahead in these final episodes.
