The following quotes are from Harry Potter and the Deathly Hallows part2.:
Bellatrix: You stupid elf! You could have killed me!
Dobby: Dobby never meant to kill! Dobby only meant to maim, or seriously injure!
OHH I LUFF THAT SCENE!!
The scene after that is absolutely awful. But that 1 was awesome.!
Dobby: [talking about Luna Lovegood] I like her very much.
Dobby: [dying] What a beautiful place... to be with friends.
Bellatrix: How dare you defy your master!
Dobby: Dobby has no master. Dobby is a free elf, and Dobby has come to save Harry Potter and his friends!
Dobby: [in kitchen, Grimmauld Place] And then Dobby saw Kreacher talking to the thief Mundungus...
Mundungus: [interrupting] I'm not a thief! You foul little... git! I'm a buyer and purveyor of wondrous objects.
Ron: You're a thief Dung, everyone knows it!
The Following quotes come from Harry Potter and the Chamber of Secrets:
Harry: Promise me something.
Dobby: Anything, sir.
Harry: Never try to save my life again.
Harry: You'd better clear off before my bones come back, Dobby, or else I might strangle you.
Dobby: [jumps off the bed] Dobby is used to death threats, sir. Dobby gets them five times a day at home.
That quote made me sad.
Dobby: Dobby is... free.
Dobby: [Dobby stands between Harry and an advancing Lucius Malfoy] You shall not harm Harry Potter!
Lucius: Avada -
[Before he can finish, Dobby sends Malfoy flying with a wave of his hand]
Hehe. "YOU SHALL NOT HARM HARRY POTTER!"
Haha. He told you so, Lucius. :))
