Max and Marianne playing as spy during World War I. Once on a mission when spying as husband and wife, Max got inspired by Marianne’s deceit.
When Max complemented Marianne for being thorough, she thinks being thorough is necessary for survival in this line of work.
Max: You’re very thorough.
Marianne: That’s why I’m still alive.
They end the evening when Marianne caught German wives stalking them on the rooftop.
Marianne: They’re watching us… now kiss me.
