First Clip From 'Deathly Hallows: Part II' : Ron and Hermione Enter the Chamber

In this new clip released by Warner Bros., Ron and Hermione enter the Chamber of Secrets to gather basilisk fangs to destroy the cup Horcrux. I am not watching this clip because I don't want to be "spoiled". I know I've read the book, but this scene is an added sequence and I want the full effect when I watch it in context with the movie. I will watch clips if they are of scenes that I wouldn't mind seeing before the movie, but this seems like too much. You can watch the clip here.
