- Farah Black: I'm an ineffectual in a generalized scramble of disappointment and incompetence.
- Dirk Gently: No, no. Listen, you're only some of those things.
- Bart Curlish: [punching Ken in the shoulder] Cheer up!
- Ken: Jesus! Why?
- Bart Curlish: Because, you know, we were having fun. You were talking to me about stuff. You know, you were asking me questions and stuff. You know, it was good.
- Ken: Yeah, and then you killed that guy.
- Bart Curlish: Potato potato.
- Ken: You're supposed to say it like, "potato po-tah-to".
- Bart Curlish: What the hell is a "po-tah-to"?
- Dirk Gently: [seeing Patrick's mansion for the first time] Fantastic! It's bloody huge. Is that a horse barn?
- Farah Black: Rhino barn, actually. Patrick loved animals. In the 90s he had a pet rhino named "Pepe."
- [Farrah is examining a wall]
- Dirk Gently: It's a wall. was there something about this wall that was special to him? Did he enjoy walls? Did he ever mention a love for walls, because that could be a clue. Perhaps the person or people who killed Patrick Spring were rogue wall-enthusiasts.
- [Farrah breaks down the wall]
- Dirk Gently: You hate these walls!
