I think the most viscerally affecting passage in HT was at the very end of chapter 28, near the end of the narrator's description of the fundamentalist takeover in the time before. In it, Luke responds to the narrator losing her job and all her rights without really blinking an eye. He still wants to make love, and can't understand why the narrator doesn't want to. He says "We still have..." and she finishes "We still have each other."
