The group stops at a small outpost. The sun is beginning to set. The weather is nice and warm, and there’s a small forest behind the outpost. Noctis, Gladio, and Prompto are discussing plans for the night while Ignis is a little bit farther away from them, staring into the forest.
The four of them stop in a small town, getting a room in the only inn they could find. Ignis, Noctis, Gladio, and Prompto sit in the room, discussing what to do next. Ignis stares out the window at the setting sun, deep in thought. He's quieter than usual, as if his mind is somewhere else. ]
