The clip The Polyjuice Wears Off from Harry Potter and the Chamber of Secrets (2002) with Tom Felton, Emma Watson
But my father did say this:
It's been 50 years since the Chamber was opened.
He wouldn't tell me who opened it. Only that they were expelled.
The last time the Chamber of Secrets was opened, a Mudblood died.
So it's only a matter of time before one of them is killed this time.
As for me
I hope it's Granger.
What's the matter with you two?
You' re acting very odd.
It's his stomachache.
Hey! Where are you going?
That was close.
Hermione, come out. We've got loads to tell you.
Wait till you see. It's awful.
Are you okay?
Do you remember me telling you
That the Polyjuice Potion was only for human transformations?
It was cat hair I plucked off Millicent Bulstrode's robes.
Look at my face.
Look at your tail.
