Barty Crouch Jr. quotes from Harry Potter and the Goblet of Fire (2005)

I'll show you mine if you show me yours.

Igor Karkaroff, you have been brought from Azkaban at your own request. Should your testament prove consequential we may be willing to order your eminent release. Until such time you will remain in the eyes of the Ministry convicted Death Eater. Do you accept these terms?

I do sir.

What do you wish to offer?

I have names, sir. There was a Rosier, Evan Rosier.

Rosier is dead.

Alastor Moody

Took a piece of me with him.

Is that all you have to offer?

Wait! I have more! There was Rookwood.

Augustus Rookwood of the Department of Mysteries?

Yes, the same. He gave information to You-Know-Who from inside the Ministry itself.

Very well, the council will deliberate. Until such time you will return to Azakaban.

Wait, wait. I have more. What about Snape, Severus Snape?

Dumbledore

I have given evidence on this matter. Snape was indeed a Death Eater prior to Lord Voldemort's downfall turned spy gave a great personal risk. Today he's no more a Death Eater than I am.

Lies! He is still faithful to the Dark Lord.

Silence! Unless the witness has any genuine name of consequents this section is now concluded.

Oh no no. I heard one more. I know for sure that this man took part in the torture by use of the Cruciatus curse of the Auror Frank Longbottom and his wife.

The name. Give me the wrenched name!

Barty Crouch [Gasps from the crowd, Karkaroff pauses for effect] Junior.

Get off of me you pathetic little men, [He is brought before his father] Hello, father. [flicks his tongue]

You're no son of mine.

I'll be welcomed back like a hero!

Dumbledore

Perhaps! Personally I've never had much time for heroes.
