It is meaningful that the narrator and R share their first kiss, because she’s always had deep feelings for him, and he appears to finally feel the same way. They’ve connected over the shared difficulty of their situation and over a mutual respect for the other. However, although they are both living through the same time, their experiences are very different, and the end of this chapter foreshadows that their differing realities (R’s full of memories and the narrator’s full of holes) will be a challenge to overcome.
