The narrator notices that another woman at the party, May Server, seems listless, and he starts to wonder if she may be the lover providing vitality to Long. Eventually, the narrator begins to construct enormously elaborate theories of who is taking vitality from whom, and whether some people are acting as screens for the real lovers.

She finishes by telling him he's crazy, and that last word leaves the narrator dismayed and overwhelmed.
