I've got to say, this is rather a strange question. I am assuming the question is, "What happened to the character played by Kenneth Branagh, named Guilderoy Lockhart?" Yes? If that is the question, all I can say is that JK Rowlings books have too many details and characters to be completely represented by a 2 or 2 and half hour movie (for example, Deathly Hallows is coming out as part 1 and part 2). In Chamber of Secrets, the only glimpse of Guilderoy we get (after he is flown up out of the chamber), is on a (moving) book cover in the window of a store in Diagon Alley. In JK's books, he shows up in book three, wandering around the magical hospital (and he is still jabbering nonsense).
