Jack, at home again, talks with Elsie, his sister. He explains that he wants to leave in order to get away from “this house and everything”, and Elsie becomes angry with Jack — not because he wants to leave her, but because he could be killed at war. Kipling comes into the room, and Elsie hides behind a chair. Kipling then tells Jack that he will get Jack into the army, somehow. After Kipling leaves, Elsie emerges, furious.

Elsie reveals that Jack went to war, not out of patriotism, but to get away from his family, particularly to escape the shadow of Kipling’s fame.

Elsie is marries George Bambridge. Her parents, though still missing Jack, are beginning to move on; they are happy for Elsie.

It has been twenty years since My Boy Jack first began, in 1913. There are rumours of war, again, and Kipling wonders why the Great War was even fought. What was the point of his son’s death, if there will just be another war?

My Boy Jack ends with Kipling reciting his poem, My Boy Jack
