Jekyll sighs. He says that Utterson is a good man for suggesting a stroll together, but he cannot join them; he dare not. Yet, he stresses that he is very glad to see Utterson, and he would like to invite the two men up, but "the place is really not fit." Utterson suggests then that they converse where they are, and the suggestion causes Jekyll to turn and smile at them. But suddenly his features convulse and freeze in an expression of "abject terror and despair." The narrator tells us that the change in Jekyll's expression was so instantaneous and so horrible that it "froze the very blood of the two gentlemen below."
Jekyll's window is jerked down so viciously that, without a word, Utterson and Enfield turn and leave the courtyard. They do not speak to one another until they reach a neighboring thoroughfare, where there are "still some stirrings of life." Both men are so pale that when they look at one another, there is "an answering horror in their eyes."
Utterson speaks softly, "God forgive us, God forgive us." Enfield nods, and the two men walk on once more in silence.
