Lise Hohenstein, Theodor Eberbach's step-sister, was presumed dead—killed by the Stasi three years back when she, her parents, and Theodor were caught trying to escape to West Germany. Turns out she survived.
She's a TSF pilot with prior Eastern European deployment experience. When she gets assigned to the 666th TSF Squadron as a replacement for the injured Pham Thi Lan, her sudden appearance raises red flags. The timing is suspicious enough that people start wondering if she's actually a Stasi plant, especially given how conveniently she shows up in Theodor's unit.
