User blog comment:Rachel6598/Hermione and Bellatrix: The Cruciatus Curse/@comment-66.41.29.82-20110720070650

Actually that's not what happened. In the movie when Bellatrix is holding Hermione down, she starts screaming because Bellatrix is carving "mudblood" in her arm with a silver dagger (the same dagger she later holds to Hermione's throat when Harry and Ron try to rescue her and then kills Dobby with). When they are showing Ron and Harry down in the cellar Hermione starts screaming again because Bellatrix is torturing her with the cruciatus curse repeatedly. Part of me also thinks that that dagger was very hot because otherwise Hermione's arm should have bled out a lot more. I don't think she bit her...but I could be wrong. Anyway hope that helps.
