H: Mr. Malfoy. Mr. Malfoy! I have something of yours.
M: Mine! I don't know what you are talking about.
H: I think you do, sir. I think you slipped the diary into Ginny Weasley's cauldron(桶，锅炉)...that day at the Diagon Alley.
M: You do, do you? Why don't you prove it? Come, Dobby.
H: Open it.
M: Dobby?
D: Master has given Dobby a sock.
M: What? I didn't give...
D: Master has given Dobby with clothes. Dobby is free.
M: You lost me my servant!
D: You shall not harm Harry Porter!
M: Your parents are meddlesome fools, too. Mark my words, Porter, one day soon...you are going to meet the same sticky end.
D: Harry Porter freed Dobby. How can Dobby ever repay him?
H: Just promise me something.
D: Anything, sir.
H: Never try to save my life again.
