How does Mrs. Dean describe the encounter between Catherine and Linton at Wuthering Heights in Chapter 23?

On a wet morning, Nelly and Cathy go to Wuthering Heights and inquire about Linton. Joseph is alone, ignoring Linton's cries that he replenish the fire in his room. Linton complains that Cathy should have visited before, because all that letter writing made him tired. Cathy tells Linton she loves him very much, and wishes they were closer; but once Heathcliff returns, she cannot visit.
