Okay, so we need to discuss the word "fey" for a minute. I always thought it meant that you had gone a bit... not crazy, but sort of not-quite-here or acting oddly. Kind of high on fairy dust, I guess. But here Eowyn describes Aragorn as being fey "like one whom the Dead call" (p. 780). So I Googled "fey" and discovered here that although it can mean "being in unnaturally high spirits," it can also mean "marked by an apprehension of death or calamity." Huh.
Anyway, isn't Merry great in this chapter? He starts out feeling oppressed by all the mountains and "long[ing] to shut out the immensity in a quiet room by a fire" (p. 774). He's sad because his friends "have all gone to some doom" (p. 779), and I get kind of melancholy myself over the course of this chapter. But he doesn't let that sadness get him down -- he refuses to be left behind, and when Theoden says he can't ride to war with the Rohirrim, he says, "It is a long way to run; but run I shall, if I cannot ride, even if I wear my feet off and arrive weeks too late" (p. 784). Sad and lonely, but undaunted. Dear Merry.
Now all roads were running together to the East to meet the coming of war and the onset of the Shadow (p. 774).
Possible Discussion Questions:
Theoden says, "In the morning counsels are best, and night changes many thoughts" (p. 783). Do you like to sleep on decisions? Or once you've made up your mind, does the passing of a night or two not change your decisions?
