Harry Potter And The Chamber of Secrets Summary and Predictions

I am about half-way through the book, and I predict that the new teacher, Gilderoy Lockhart, has something to do with all of the children turning to stone [because you can never trust a teacher at Hogwarts] and also because he has all of these wild stories and 'experiences' but he hasn't, so far, been able to demonstrate any further knowledge of the things he teaches the 2nd years about.  I also predict that Draco also has a part in it because of the discussions he had with Crabbe and Goyle [his friends] and how said he knew how to open the chamber of secrets.
