Season 7, Episode 19
Of Grave Importance
Sam and Dean get a call from Annie Hawkins, an old hunter friend, asking for help on a case. When they arrive in town, they find out Annie has disappeared. They trace her last whereabouts to an old abandoned house that is haunted by a powerful ghost. Unknown to them, the ghost of Bobby is following them around, having tied himself to his old flask that they carry. He finds the house populated by mostly mindless ghosts and the spirit of Whitman Van Ness. Bobby discovers the ghost of Annie and the two try to solve the murders.
- Call Back: Dean's line towards the end of the episode about how "everything has an end" stems from his day filling in for Death in the episode "Appointment in Samarra", where he learned to respect the natural order of life and death.
- Character Development: Where Dean has previously resorted to resurrection and seances in past seasons, in this one he speaks to both Jo and Bobby's spirits about the natural order of things after death, likely due to learning just how such imbalances can hurt others last season when making his deal with Death.
- Dramatic Irony: Bobby tells Dean and Sam they didn't "know" Annie as well as he did. They did, actually, and they share an awkward look.
- Fate Worse than Death: Bobby and Annie discover that, after time, ghosts develop a kind of Alzheimer's and eventually disintegrate into nothing. Loudly.
- Haunted House: The Van Ness House.
- Insistent Terminology: Fancy lady.
- Invisible Main Character: Bobby hasn't managed to master the tricks to being a ghost, so he has difficulty alerting the Winchesters to his presence. This is particularly frustrating to him.
- One Steve Limit: Annie, there was already more than one character named Anna.
- Shout-Out: To Ghost, of course.
- Soul Power: Van Ness consumes ghosts to become more powerful.
- Cessation of Existence: Discussed. Bobby and Annie believe this is what happens to ghosts whose bodies are burned.
- We Hardly Knew Ye: Annie. Played with in that we meet and get to know her more after she dies.
