The clip Devil's snare from Harry Potter and the Sorcerer's Stone (2001) with Emma Watson, Rupert Grint
Lucky this plant thing's here, really.
Stop moving, both of you. This is Devil's Snare.
You have to relax. If you don't, it will only kill you faster.
Kill us faster? Oh, now I can relax!
Now what are we gonna do?
Hermione, where are you?
Do what I say! Trust me.
Are you okay?
Yeah, I'm fine.
He's not relaxing, is he?
We've gotta do something.
I remember reading something in Herbology.
Devil's Snare, Devil's Snare. It's deadly fun but will sulk in the sun! That's it! It hates sunlight.
Ron, you okay?
Lucky we didn't panic.
Lucky Hermione pays attention in Herbology.
