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.
