Let me get this straight, Professor.
You're actually giving us permission to do this?
That is correct, Longbottom.
To blow it up? Boom?
Boom!
Wicked.
How on Earth are we going to do that?
Why don't you confer with Mr Finnigan?
As I recall,
he has a particular proclivity for pyrotechnics.
I can bring it down. That's the spirit...away you go.
You do realise, of course,
we can't keep out You-Know-Who indefinitely.
That doesn't mean we can't delay him.
And his name is Voldemort!
Filius, you might as well use it.
He's going to try to kill you either way.
Piertotum
locomotor!
Hogwarts is threatened.
Man the boundaries, protect us,
do your duty to our school!
I've always wanted to use that spell.
