Cathy and Nelly ride to the location on the moors where they are to meet Linton, but he's not there—instead they find him nearby Wuthering Heights. He appears even weaker than usual, but he insists that he is in fact getting stronger.
Linton is now so weak that he can barely stand nature at all. He needs the protection of a house, of civilization, to keep him alive.
Linton seems anxious during the entire visit and keeps glancing over his shoulder at Wuthering Heights. As the visit ends, Cathy promises to meet Linton in the same place the following Thursday. As they travel home, Cathy and Nelly discuss how much more ill Linton seems, but decide that they'll have to wait until the next visit to get a real sense of his health.
Linton's glances toward Wuthering Heights convey his nervousness about Heathcliff, and make it clear that meeting with Cathy is only partially his own idea.
