The clip Opening up to Lupin from Harry Potter and the Prisoner of Azkaban (2004) with Daniel Radcliffe, David Thewlis
Professor, can I ask you something?
You want to know why I stopped you facing that boggart, yes?
I thought it'd be obvious.
I assumed it would take the shape of Lord Voldemort.
I did think of Voldemort at first.
But then I remembered that night on the train and the dementor.
I'm very impressed.
That suggests what you fear the most is fear itself.
This is very wise.
Before I fainted I heard something.
A woman screaming.
Dementors force us to relive our very worst memories.
Our pain becomes their power.
I think it was my mother the night she was murdered.
The very first time I saw you, Harry, I recognized you immediately.
Not by your scar, by your eyes.
They're your mother, Lily's.
Oh, yes. I knew her.
Your mother was there for me at a time when no one else was.
Not only was she a singularly gifted witch she was also an uncommonly kind woman.
She had a way of seeing the beauty in others even, and most especially, when that person could not see it in themselves.
And your father, James, on the other hand he...
He had a certain, shall we say, talent for trouble.
A talent, rumor has it, he passed on to you.
You're more like them than you know, Harry.
In time, you'll come to see just how much.
Honeyduke's Sweetshop is brilliant, but nothing beats Zonko's Joke Shop.
