Hermione - Look at you, playing with your cards! Pathetic! We’ve got final exams coming soon.
Ron - I’m ready! Ask me any question.
Hermione - Alright! What are the three most crucial ingredients in a forgetfulness potion?

Hermione - And what, may I ask, are you supposed to do if this comes up in the final exam?
Ron - Copy off you!
Hermione - No you wont! Besides, according to Professor McGonagall, we are to be given special quills, bewitched with an anti-cheating spell.
Ron - That’s insulting! It’s as if they don’t trust us!
