Chilling Adventures Of Sabrina Part 3: What Does The Ending Really Mean?

2. The Eldritch Abomination Is Coming

Father Blackwood's inability to accept the rise of Sabrina Spellman for the all-powerful being that she is - or the fact that her family rose to heights he could have never imagined - led him down another dark path in the finale, as he carved open that mysterious egg with a knife, calling upon the Eldritch terrors as he did so.

With whatever that creature is now free, and Blackwood offering himself up as a vessel (*cue evil villainous laughing*), it's clear that his mission to destroy the Spellmans will return to prominence in Part 4.

Whether the monster will do his bidding remains to be seen, but with the Old Gods and the Pagans now out of the picture thanks to Sabrina's powerful coven, he's going to need a bigger, well, everything.
