Most importantly, Gilderoy Lockhart is portrayed here as a contrast for Harry. Lockhart vastly misunderstands Harry's famous history. Harry is humiliated when people like Colin Creevey approach in varying states of awe; any special treatment makes him uncomfortable, especially since Draco Malfoy resentfully mocks whatever "famous" attention Harry Potter happens to be getting. So for Harry to get caught twice by Lockhart in situations that bring him extra attention is horrifying; he does not want Lockhart to identify with him, to give him pointers on fame and to involve him in photo sessions. Lockhart, we begin to see in this chapter, will spare no sacrifice in order to arrive at some sort of eminence, while Harry, who was thrust into eminence without being knowing or wanting it, will do anything he can in order to feel that he is treated fairly despite his fame. He wants to succeed on his own merit, not resting back upon the history of the scar on his forehead, as opposed to Lockhart, who we soon see has little integrity on what he will do to become famous, and in how he will handle that fame. Lockhart revels in the end result, while Harry strives to make worthwhile the process.
