Harry Potter and the Prisoner of Azkaban2004

[Professor Snape has caught Harry in a hallway.]

Professor Snape:
Potter. What are you doing wandering the corridors at night?

Harry:
I was sleepwalking.

Snape:
How extraordinarily like your father, you are, Potter. He too was exceedingly arrogant, strutting about the castle.

Harry:
[irritated] My dad didn't strut. And nor do I. Now if you don't mind, I would appreciate it if you would lower your wand.

Snape:
[Lowers his wand, level with the pocket on the hooded sweater Harry is wearing] Turn out your pockets. [Harry just stands there] [sternly] Turn out your pockets. [Harry takes out the Marauder's Map] What's this?

Harry:
Spare bit of parchment.

Snape:
Really? Open it. [Harry opens the map; Snape puts his wand on the map] Reveal your secrets. [To Harry, as the logo seems to appear] Read it.

Harry:
[reading the map's text] "Messrs. Moony, Wormtail, Padfoot and Prongs... offer their compliments to Professor Snape and..."

Snape:
Go on.

Harry:
[still reading, amused] "...and request that he keep his abnormally large nose out of other people's business."

Snape:
Why you insolent, little--!

Professor Lupin:
[approaching Snape from the back] Professor.

Snape:
Well, well. Lupin. Out for a little walk in the moonlight, are we?

Lupin:
[to Harry] Harry, are you all right?

Snape:
That remains to be seen. [takes the Marauder's Map] I have just now confiscated a rather curious artifact from Mr. Potter. Take a look, Lupin. Supposed to be your area of expertise. Clearly, it's full of Dark Magic.

Lupin:
I seriously doubt it, Severus. It looks to me as though it's merely a parchment designed to insult anyone who tries to read it. [chuckles] I suspect it's a Zonko product. Nevertheless, I shall investigate any hidden qualities it may possess. It is, after all, as you say, my area of expertise. [to Harry] Harry, would you come with me, please. [to Professor Snape] Professor, good night.
