- And This Is for...: Sydney, confronting the man who killed his parents.Sydney: [Jacob is] all the family I have left because the rest you murdered because they were of no use to you... This is for Jean Mikhail, and this is for Greta!
- Bait-and-Switch: When Miss Parker interrupts Sydney's confrontation with the man who killed his parents, she reminds Sydney of how he was there for her when her mother died, and it seems like she's leading up to telling him that he's better than this — but she's actually leading up to say that she completely understands and approves of Sydney's desire for revenge.
- Big "OMG!": Played for drama. Gibbs remembers one of the victims shouting this, while dying from exposure.
- Brick Joke: The first scene with Miss Parker and Sydney has Sydney start to tell a joke and then get distracted by the arrival of the plot just as he's about to deliver the punchline. In their final scene in the episode, after tying off the last plot threads, Miss Parker asks him to finish the joke, and he obliges.
- Bungled Suicide: Dan throws himself in front of an oncoming bus. He is left badly injured, but Jarod's intervention at the scene kept him alive long enough for first responders to arrive and get him to a hospital.
- Continuity Nod: While talking to Dan about families, Jarod shows him photos of Margaret and Kyle, as well as Major Charles's Distinguished Flying Cross.
- Dramatic Irony: The first responder congratulates Jarod for how he tended to Dan, saying he should've been a doctor.
- He Knows Too Much: Strickland is involved in drug-smuggling, but Larry Meyers found out and blackmailed him for a cut of the profits. Strickland ultimately sabotaged the seal in order to silence Larry, with the other victims just being in the wrong place at the wrong time.
- Herr Doktor: Dr. Werner Krieg, a Nazi who did experiments on human subjects at Dachau.
- Lightbulb Joke: Sydney, in an unusually good mood, tells the standard psychiatrist light bulb joke. ("One. But the light bulb has to want to change.")

- Nazi Grandpa: Dr. Krieg, who did human experimentation at Dachau during the War and, when Sydney finds him, is living in the US as a kindly old optometrist.
- "Not So Different" Remark: When Sydney confronts Krieg, the Nazi scientist who experimented on him and his brother when they were children, Krieg points out he's carried on the same work at the Centre.
- Parting-Words Regret: Jarod meets Dan Healy, who's been blamed for an accident that killed three co-workers. It turned into a media circus and Dan thought he could take the pressure off his family by throwing himself in front of a bus. Jarod saves his life, but Dan's son Todd still takes all of this pretty hard.Todd: Um, the night before, before he was on the bench with you, we had a really bad fight, and I said some stupid stuff. I told him that the accident was his fault. I told...
Jarod: What did you say?
Todd: I told him he didn't deserve to live. I don't want him to die. I don't want my father to die. - Ransacked Room: Sydney disappears, and his office is ransacked. The audience is shown that he ransacked the office himself, looking for something he'd hidden away and now suddenly urgently needed.
