The rest of the chapter follows this impulse, though the available evidence does not detail the specific scenes that unfold after this declaration. The title “Necessity” underscores that the narrator’s choice is not casual or optional; it is a compulsion rooted in concern for Christina’s fate and the desire to move beyond stasis.
