The next morning Nag's wife, Nagaina, mourns the death of Nag.
I will kill the man and the mongoose and will have the garden to myself and my babies.
Rikki-Tikki found Nagaina's eggs and stomped on all of them except one. He stopped because a bird told Rikki-Tikki that Nagaina was about to bite the man.
Rikki-Tikki called out to Nagaina and told her he had Nagaina's last egg and that he killed Nag.
Nagaina slithered toward Rikki-Tikki and they fought. Rikkii-Tikki bit her neck but did not kill her. She slithered away with the egg into her old hole. Rikki-Tikki followed Nagaina killed her and saved the man and the gardens animals.
