The next terror graces Greendale. Sabrina bonds with a new classmate... and finds herself in a squeamish predicament. Roz uncovers a shocking truth.
Tropes in this episode:
- Cthulhumanoid: Sycorax the water-witch has tentacles on her face.
- Evil All Along: Caliban is revealed to be faking his Heel–Face Turn, seeking to kill Lilith and her newborn child because they're a threat to his and Sabrina Morningstar's rule of Hell even though Sabrina wouldn't approve if she knew. Although he's not faking his feelings for her.
- Red Herring: At first we're set up to think that new student Lucas is the host for the Weird, but it turns out to be Sabrina Spellman herself.
- The Reveal: Roz is revealed to be a witch with future-sight, which her grandma's ghost confirms — saying that the women of the Walker family called themselves "Cunning Women" to avoid being burnt at the stake.
- Shout-Out: Lucas Hunt claims to have transferred to Greendale from Innsmouth High, and the Weird is a cephalopod-esque Eldritch Abomination — both being references to the Cthulhu Mythos. Ambrose even notes the connection to H.P. Lovecraft's writings when informing Sabrina she's been possessed by it.
- Transformation of the Possessed: The Weird's hosts begin to transform into squid-human hybrids as it bonds to them.
