Harry told McLaggen about Hermione confunding him at tryouts. Days pass, and Hermione goes to take her apparition test at Hogwarts. It is an open spectacle to simulate the real pressures of apparition.
"Confundus Bitch," whispers McLaggen, annoyed with his lost chance in Quidditch. Hermione turned and chaos ensued. Hermione had Splinched, with a leg here, an arm there, and her torso and head in a corner. She screamed, aghast at the development.
"AHHHHHHHHHHHH! WHAT HAPPENED!" Due to her spectacular failure, he examiner marked her down as to never get an Apparition license. Dejected, Hermione runs to her dorm in tears.
