Part 4/9:
Doctor Who is not alone; he is accompanied by one of Clara's students, the troubled Maebe. The child's emotional struggles resonate through the storyline, as it is revealed that she hears voices—a consequence of her sister's mysterious disappearance. This emotional weight contrasts with the unfolding disaster and presents a compelling dynamic, suggesting that the solutions to humanity's crisis may lie within the innocent perceptions of a child.
As the adults attempt to piece together the mystery of the trees, Clara and Danny confront their guilt regarding Maebe's situation and their roles in the chaos enveloping them. The narrative flips between the adult world and the children's innocent wonder, culminating in maebe's drawings that depict a wrathful sun and trees.
