Later that evening, Alina is in her bed, but she cannot sleep. She gets up and wanders down the hall into the war room, where Kirigan is, studying a map. He offers a drink, and she accepts. Then, they talk about the war. As they talk, Kirigan becomes more vulnerable and releases shadows into the room. Alina tries to comfort him, but as soon as her hand presses against his, she summons enough light that almost blinds the room.
Once the light dies down, Alina reassures Kirigan, and he emotionally touches her face. They are about to kiss, but Alina says she should go. She leaves the war room, and he almost goes after her.

However, a Fjerdan begins shooting from a machine gun, knocking them out.
There is a flashback of Mal's first day in the First Army.
