Oh, we love the title of this one—it's so tricky. See, we have two characters: the comrade and the narrator. And one of them—the comrade—has so much faith in a coming communist revolution. We're told: "In spite of Hungary, he believed altogether in the world revolution" (3). So the title's just a shout-out to the young man, right? Not so fast…
You know the square of oilcloth the comrade carries? The one he uses to get help along his journey? It has a note from Commie HQ asking comrades to feed him and help him travel and such. And who's helping the young man? The narrator. And this means, that though he's pessimistic about world revolution, the narrator is also a comrade—and this means he's a revolutionary.
So you tell us: Who's the revolutionist now?
