Mowgli thrust his dead branch into the fire till the twigs lit and crackled, and whirled it above his head among the cowering wolves.
"Thou art the master," said Bagheera, in an undertone. "Save Akela from the death. He was ever thy friend."
Akela, the grim old wolf who had never asked for mercy in his life, gave one piteous look at Mowgli as the boy stood all naked, his long black hair tossing over his shoulders in the light of the blazing branch that made the shadows jump and quiver.
Answer:
Mowgli is asked to save Akela
Step-by-step explanation:
According to the given excerpt, it is narrated that Mowgli held a twig that was lit with fire to make threatening gestures to the wolves who were his enemies.
However, Bagheera begged Mowgli to spare the life of Akela because he was his friend.
Therefore, the detail from the passage that best supports this theme, "Inner power is revealed during times of change" is that Mowgli is asked to save Akela.
