i just watched this but my dvd had a glitch and suddenly, right at the moment when mel was trying to get the crowbar with her foot, the film jumped straight to the driver going through the girls' pics on their digital camera at some garage.. and then mel was suddenly a blonde and she and jules were trapped in a bathroom.. wtf did i miss???

did mel hit/kill andy the co-conspirator over the head with that crowbar and kill him? and why was her hair suddenly blonde?

help!
