In a bizarre turn of events, the Vietcong soldier who lives in the tunnels treats his enemies, the American troops, with politeness and courtesy. More oddly, the Americans don’t acknowledge his behavior as strange in the slightest. This reinforces the sense of magical realism in the novel—the most extraordinary events are taken for granted by all the characters. For us as readers, however, the fantastical elements are meant to emphasize the tone of surreality and confusion.
