Hoa has already come up several times throughout the novel, so it’s evident that she’s someone who made a lasting impression on Kien. It’s not clear, however, what happened to her. By suddenly shifting from the suspenseful train scene to this story about Hoa, the narrative once again mimics the fragmentary, discombobulated way that trauma impacts memory. Instead of telling the story linearly, Kien hops from one memory to the next, letting his lingering, traumatic recollections guide his storytelling. The novel thus has its own kind of internal logic—a logic that only makes sense through a lens of extreme grief.
