Schwarzes Marken: #04

Irisdina introduces Lise to the squadron, to the shock of Theodor, who cannot believe he's been reunited with his sister after being separated three years ago. Irisdina and Gretel express concern Lise may have been brainwashed, sent as a spy against the National People's Army and the 666th specifically. Irisdina orders Theodor to figure out what Lise is up to. During a training exercise, they meet up with European Union forces, and join an operation to retake BETA-held territory in the former Poland with the goal of expanding a beachhead near Gdańsk.
