The Charmed Ones and Abigael track a demonic Kyon; Harry makes a shocking discovery about the true nature of Whitelighters.
Tropes in this episode:
- Literal Split Personality: Every Whitelighter is made by splitting a person into two versions of themselves, one good, one evil. The good half becomes the Whitelighter, while the evil half becomes a Darklighter.
- Re-Power: Maggie's got a new power: Foresight, the same power Phoebe started out with in the original series.
- The Reveal:
- Abigael is the daughter of Alaister Kaine.
- Every Whitelighter is really the light half of a person, and has a Darklighter counterpart. The assassin they've been dealing with is really Harry's Darklighter.
- You Killed My Father: Abigael has a bit of a grudge against the Charmed Ones for killing her father and half-brother.
