Finnick is dreading this conversation. He's going out into the world, he's going to be fighting for the rebellion (even if it is in a more limited fashion), but he's going to be away from Annie. He's not sure how she's going to handle this, and he's not sure what he can say to make it okay, but he knows that he has to do this; he can't just sit idle any longer.
When he opens the compartment door, Annie is sitting on their bed, warily eyeing the schedule that has been inked onto her arm. "Annie?" he asks softly. She looks up, and her face brightens into a smile, just for a moment. Then she seems to notice the way he's hunched his shoulders and biting his lip.
"What is it, Finnick?" she asks, standing up and striding towards him. Haltingly, he begins to tell her that he's been assigned to a fighting squad, that he's going to be fighting now, that he won't be here, for a little while at least. Her eyes darken, and she straightens her spine, insisting that she needs to go with him, that they'll fight together. Finnick's heart is breaking, but at the same time he feels an overwhelming sense of pride, that this broken woman in front of him is so determined to fight, even though she's so scarred and battered. So he pulls her into his chest and hugs her tight, while explaining that she can't go, that she hasn't been trained, that she doesn't have to worry about him, that he'll be back before she knows it. Finally she looks up at him and says something that breaks his heart all over again.
"Finnick, between the two of us, we've been forced to participate in three Hunger Games. The odds have never been in our favor, and they certainly aren't in yours if you go,"
"Annie…"
"I know you have to go. I know you, Finnick. I don't want you to, but I know you need to."
They stare into each other's eyes for a few minutes, blinking back tears, and then they're kissing each other with the type of desperation only two people who have struggled to survive as much as they have can muster.
In the morning, they eat breakfast together in the same sort of silence they used to exist in at the beach. Annie walks him all the way to the station where the hovercraft is waiting to deliver both he and his unit to their location. He turns to her, and he doesn't know what to say-words seem so inadequate right now, as he heads off into a war that he can't guarantee he'll return from. Annie seems to be struggling to find the right words too, so they just stand there and look at each other, holding hands, as the minutes tick by.
Finally, Boggs is calling for Finnick, telling him it's time to board the hovercraft. He kisses Annie, in the same brief way she kissed him before he headed off to his first Games. He says "I love you," and she says "I love you too," and then he forces himself to turn around, to walk with his head held high, all the way inside of the hovercraft. He peers out one of the windows, and sees Annie is still standing there. He watches her until she's out of sight.
