As a dead man on a park bench in the Tiergarten grabs the attention of the homicide squad, Toni gets caught and Charlotte makes a terrible decision. Charlotte conceals evidence of her sister's culpability in the department store robbery, and as a result is fired from the Berlin police. Meanwhile, it is revealed that Gereon is not really a Nazi. He is conducting The Infiltration of the Berlin SA.
Tropes:
- Affair Hair: One piece of evidence brought forward to incriminate Toni in the robbery case is a red hair found on the jacket she left behind.
- Drowning My Sorrows: Charlotte heads over to My Local to get drunk after being fired from her job.
- Incriminating Indifference: The irritated look on Gereon and The Coroner's faces when the wife of the killed Friedhelm Oelschläger doesn't show any signs of mourning while Identifying the Body.
- The Reveal: The audience learns that Gereon was tasked to infiltrate the SA as The Mole and doesn't actually share their worldview.
- Slashed Throat: Friedhelm Oelschläger was killed this way, apparently by someone who knows how to handle a scalpel.
- Stress Vomit: Gereon vomits in the bathroom after the autopsy of the elderly man.
- Trashcan Bonfire: Toni's fellow child thieves are shown huddling around a trashcan bonfire in an abandoned building. Toni is kicked out of the group when she returns without either her boyfriend (who died in the robbery) or any jewels.
- Turn in Your Badge: Charlotte gets fired from her job at the police station and has to hand over her badge to her superior.
