- The Con: The con on Greta continues. Otto informs her Fritz didn't make it, giving her his "personal effects" – a knife and a handkerchief embroidered with a loving message from his mother. Otto blames Benda, calling him the "Jewish sow". The plan succeeds, Greta agrees to do whatever is necessary.
- Deliberate Values Dissonance: Helga mentions that she found it a bit over the top to have a radio in the room. Sensory Overload much.

Just before Seegers is brought before the press, Reichpraesident Hindenburg arrives on the scene, and steals Seegers away.

- "Eureka!" Moment: Gereon notices when Moritz whistles the Mackie Messer theme. He also hears a radio broadcast mentioning Stresemann, Briand, Prangertag and the The Threepenny Opera, and suddenly realizes the plans of the Black Reichswehr conspirators. He rushes to foil them.
- He Knows Too Much: Bruno shoots the second assassin when the latter gets captured by Gereon.
- It Was Here, I Swear!: Benda visits the arrested Gereon, ordering his immediate release. However, when they go to retrieve the body of the assassin, it is mysteriously missing.
- It Will Never Catch On: Foreign ministers Stresemann and Briand attend one of the first performances of Brecht‘s The Threepenny Opera, which would go down in history as one of the most influential stage plays of the century. They end up walking out halfway through its first act.

- Media Scrum: When Seegers leaves the cancelled press conference and walks towards the car that would take him away, he is surrounded by hordes of reporters wanting to know why he was invited.
- Mugged for Disguise: Gereon infiltrates the opera via the fire escape, knocks out a guard and dons his uniform.
- The Secret of Long Pork Pies: The Armenian threatens Charlotte to process her into meat if she doesn't talk. Luckily, she now has the information sought after.
