The charges Brinker levels against Gene in the Butt Room — "rankest treachery," "practically fratricide" — strike directly at his fear of being accused of causing Finny's accident. Suddenly Gene stands as "prisoner," with the scene of his crime openly identified — "that funereal tree by the river."
When one boy attacks with the bluntness of raw curiosity, Gene defends himself with ironic humor — silly confessions to serious crimes — but he cannot make himself joke about his part in Finny's fall. In this moment, Gene does try to admit his crime — as an absurdity, to disguise his guilt — but his throat tightens and words fail him.
Gene cannot yet truly acknowledge his guilt to others — or even, really, to himself, despite his earlier attempts to confess to Finny. Gene's guilt remains as a part of his deepest nature, and it will re-emerge in a more serious trial later in the novel — a trial that neither he nor Finny can escape.
After the mock trial in the Butt Room, the focus of the chapter turns to the war as winter comes to Devon. As part of the war effort, the school boys join in apple-picking — humorously celebrated in Brinker's Keatsian "Apple Ode" — and take up shovels against the heavy New England snow on the nearby railroad tracks.
The description of the railroad scene — grimy, run-down, industrial — creates a clear contrast with the sheltered Devon campus and the idyllic apple orchard. Here, at last, the boys play their part in a larger, rougher world, closer to the war and their own adulthood. They work all day under the sullen supervision of a railroad man — who seems an older version of Quackenbush — performing heavy labor with a real purpose.
