Based on the imagery in this excerpt, what is happening in the scene? Because he is so cute and vulnerable, Mother Wolf knows that Mowgli will easily be accepted by the Pack.
Mother Wolf understands the Law of the Jungle and is willing to accept whatever decision the Pack makes about Mowgli.
Although Mowgli is playing quite happily, Mother Wolf is making the decision to fight the entire wolf pack if they decide to give Mowgli to Shere Khan.
Mother Wolf is very worried about the vulnerable man cub, who is blissfully unaware that he is in danger of being killed by the wolves or the tiger.
