The two have struck up a friendship, and Francis manages to get Leith up and on the path to a doctor by getting him to think about what he's fighting for: Greer.

• Nicole wakes up after a night of sex with Henri to find him trying on her jewelry. When she asks, noting that he has marks on his chest that would've likely come from a corset, he admits he does sometimes like wearing women's clothing. This is heartwarming for two reasons. First, Henri is completely unashamed and unapologetic — yes, he hides it, but he fully recognizes that it's because society is too closed-minded to accept it, not because he should hide it. Second, Nicole is 100% cool with it, and doesn't judge him even slightly; she was simply curious.
• Mary dies - when she opens her eyes, there is Francis. In death, finally, she is happy - no war, politics, just her and Francis and a lot of ghost sex...
