This choice highlights how the hooded figure's choice to withhold information creates suspense within the story, propelling the plot forward as Celeste seeks to uncover the truth surrounding her past. As she navigates the uncertainties and secrets, the tension amplifies, engaging the reader and motivating her actions. This lack of transparency keeps the audience invested in the unfolding narrative, ultimately shaping the direction and stakes of the plot.
