Miss Thorne wants to perform a show “for the war effort,” which suggests that revenue from ticket sales will go toward supporting English soldiers somehow. This civilians support for soldiers shows one way that civilians can be materially involved in war even though they aren’t fighting. After Zach first proposes that he and his friends join the show, the friends all try to identify each other’s relevant talents: Ginnie, who is good at sewing, can make costumes, artistic Willie can paint sets, and so on. This conversation shows how the children support one another’s talents, even as showboating Zach humorously claims he’ll “volunteer” himself for a main role.
