Lockwood is clearly blind to the reality of the situation, although the extent of his misinterpretations is not fully realized. He is the first of many narrators to tell the story from a point of view that is neither omniscient nor unbiased. In Wuthering Heights, stories are often told within stories, with much of the information being revealed second-handed. Lockwood is an outsider who serves as the impetus for Nelly first to tell the story of Heathcliff and Catherine, and then to relate the story of their respective children.
In addition to Lockwood and Heathcliff, two servants are introduced in Chapter 1. The first is Joseph, an old man with a nasty disposition who has a sense of religious fanaticism; the other is only referred to as a "lusty dame" and is later identified as Zillah.
These characters are presented realistically, and other signs of realism are the depictions of the dogs and the details of the farmhouse furnishings. Brontë provides these kinds of details throughout the novel because having a sense of realism and authenticity is an important aspect of Wuthering Heights. Another important aspect is ownership of property, and even though the name "Hareton Earnshaw" is not explained, the family name plays an important part of Wuthering Heights. Because the opening chapter raises more questions than it answers, it serves as a hook to capture the attention of readers and encourage them to continue reading.
