Lucius Malfoy: Who was it?

Albus Dumbledore: Voldemort.

Lucius Malfoy: Ah.

Albus Dumbledore: Only this time he chose to act through somebody else... by means of this.

Lucius Malfoy: I see.

Albus Dumbledore: Fortunately, our young Mr. Potter discovered it. One hopes that no more of Lord Voldemort's old school-things... should find their way into innocent hands. The consequences for the one responsible would be... severe.

Lucius Malfoy: Well, let us hope... that Mr. Potter will always be around to save the day.

Harry Potter: Don't worry. I will be.
