Mace Windu: Has the boy shown any violence or aggression since you injected him with midi-chlorians?
Anakin: I didn't do anything!
Qui-Gon: Uh... there was the fight with the giant sand creature...
Qui-Gon: No, wait, I fought that off single-handedly.
Mace Windu: Anything else?
Qui-Gon: Can't think of anything.
Mace Windu: Nothing at all...?
Qui-Gon: Nope.
Anakin: Greedo started it! He punched first!
Mace Windu: Quiet, youngling. I'm speaking to the grown-ups. Obi-Wan?
Obi-Wan: I... wasn't there. I didn't actually see anything.
Anakin: I definitely didn't kill him!
Mace Windu: Hmmmm.
Anakin: He deserved it anyway!
Mace Windu: Be quiet, boy!
Anakin: Nobody ever listens to me! I hate you all! I'll kill you! I've done it before and I'll do it again!
