Finally, it’s implied that Momma was killed in the bus accident that the man references here. This means that the description of Momma “resting peacefully” in Lewiston at the beginning of the novel was a euphemism for death rather than actual rest or healing. The fact that this revelation happens so far into the novel (and in an indirect way) suggests that up until now, Sal has been lying to herself—and, by extension, to the reader—so that she wouldn’t have to face her grief over Momma. By telling herself that she could bring Momma home if she got to Lewiston in time, Sal was trying to avoid the painful truth that it’s impossible for Momma to come back, though she did know this on some level. Furthermore, the fact that Momma died in a bus accident is probably why Sal was nervous to travel, and why she’s been so preoccupied with buses on the mountain roads. Now, as Sal confronts the site of her mother’s death, she must finally rely on her own perceptions (rather than what Dad and her grandparents have told her) and face the truth of what happened.
