In The Magician's Nephew, Aslan's face likely shows deep understanding and compassion when Digory wishes for his mother's health, indicating to Digory Aslan's awareness and wisdom.
Step-by-step explanation:
In The Magician's Nephew, when Digory expresses his wish for something to make his mother well a second time, he observes something profound in Aslan's face. While the text of the novel doesn't describe Digory’s exact observation, it implies that Aslan shows a deep understanding and compassion, which can be incredibly moving and telling for Digory. This indicates to Digory that Aslan is aware of his pain and desperation but also suggests Aslan's wisdom and possibly his ability to heal. This moment is significant as it helps Digory understand the depth of Aslan’s character and hints at the possibility of his mother's healing. It is a critical turning point in the narrative, as it strengthens the bond between Digory and Aslan and sets the stage for events to follow.
