1x3 - Schwarzes Marken

Katia and the injured Pham are brought inside the besieged Fort Neuenhagen. Back at Bebersee Base, Gretel asks Theodor if he and Irisdina are plotting something. She reveals that five years earlier, a coup against the Stasi led by General Strachwitz was foiled, and the Stasi effectively erased him from history. Gretel also tells Theodor the story of Irisdina selling out her brother to the Stasi is almost certainly a lie. Armed with this information, Theodor arranges a meeting with Irisdina in an old church, where she admits her "dog of the Stasi" persona is a cover, and she's plotting to overthrow the Stasi herself, and recruits Theodor into her cause.
