The Avatars ask Leo to save a demonic Seer, who betrayed her kind and might be a clue to turning the Charmed Ones to the Avatars' side. The Seer has information on the Avatars, and she is ready to divulge it if the Elders make her human. With the Seer's help, Darryl finally finds Sheridan. Meanwhile, a faction of demons release Zankou, the Source's rival, from his prison as a last-ditch effort to stop the Seer.
- And I Must Scream: Zankou was entirely conscious throughout his imprisonment. He reveals he was also aware of the wider world, such as how the Source is now dead and the coming Avatar threat.
- Eviler Than Thou: The Source considered Zankou too dangerous.
- Given Name Reveal: Towards the end of the episode, the Seer reveals her name is Kira.
- Godzilla Threshold: Between the Avatar threat and the Seer turning on them to save herself, the demons are willing to release someone that even the Source feared.
- Sealed Evil in a Can: Zankou. He was disembodied and placed inside a beam of light.
- What the Hell, Hero?: The sisters are quite unhappy to learn that Leo has secretly been an Avatar.
