Tatsu contacts Babs and Kara to help her find and exorcise a ghost that is haunting a boarding school. Their search leads them to learn of the history of the boarding school and they help the ghost come to its eternal rest.
Tropes:
- Adaptational Heroism: This show's version of Silver Banshee is the ghost of an innocent woman with a legitimate beef.
- Arbitrary Skepticism: Despite having her soul taken by Katana in the past (which Katana directly references), Kara refuses to believe in the existence of ghosts.Katana: I literally turned you into one.
- Brief Accent Imitation: Tatsu's Scottish accent while undercover as a student.
- Dean Bitterman: Until the end of the episode, Headmaster McDougal is a strict, no-nonsense headmaster who bans things like custom shoelaces.
- Shout-Out: The photon packs Babs uses to capture the ghosts are heavily based on Ghostbusters.
- Sibling Murder: Bevin McDougal resented his sister for being chosen over him as head of the clan, and killed her to steal that honor.
- Sins of the Father: Siobhan haunts Headmaster McDougal specifically because he is the descendant of Siobhan's brother and murderer.
- The End... Or Is It?: While the Silver Banshee's rampage is averted, the episode ends with faint wisps of her ghostly form passing by, suggesting she hasn't moved on from the mortal plane yet.
- Unfinished Business: Siobhan wants to get back what Bevin stole from her: The brooch designating her as head of Clan McDougal. The headmaster gives it to her after learning of her tragic death.
