Before leaving for the front, Frederic and Catherine meet. Frederic buys a gun because he has lost his. They decide to get a room together, and stop to buy her a nightgown.
In the room, Catherine tells Frederic she feels like a whore for the first time, and that she doesn’t like it.
They drink and eat, and she feels better. They talk about their families a little bit, and Frederic wants to know where she will give birth to their child, but she is not sure.
He asks when she will write him, and she says she will write daily.
He has to leave so that he doesn’t miss the train, and they get ready to leave the hotel.
