Tropes in this episode:
- Awesome, but Impractical: The sonic boom spell that Mel uses helps save the day; but, also injures Macy.
- Back for the Dead: Cam from the first episode reappears so he can be killed by the Harbinger.
- Danger Room Cold Open: Begins with Harry putting the sisters through a training exercise
- My Greatest Failure: Harry talks about his previous charge Fiona, and how he feels he failed to protect her.
- Nature Abhors a Virgin: The Harbinger feeds off virgin blood. Macy uses her status as a virgin to lure it out.
- Personal Gain Hurts: Maggie's overuse of magic to throw a party puts her in a tough spot when finally facing the Harbinger.
