Shmi: He what?
Qui-Gon: Some green kid was muscling in on his turf, and Anakin whacked him.
Qui-Gon: It was hardcore.
Shmi: You are lying!
Shmi: Make it not be true...
Qui-Gon: Er... no, really. I think it was a crit.
Shmi: Why didn't you do something?
Qui-Gon: Um... there was no time. He just went completely berserk.
Anakin: I suddenly got really angry. I don't know what happened.
Shmi: Oh, Anakin. The authorities will be looking for you now. We have to get you to safety.
Qui-Gon: But... Watto still owns him.
Shmi: So Watto will owe the blood debt! This is terrible.
Shmi: Oh Anakin, how could you do such a thing?
Qui-Gon: That green kid totally looked like he deserved it.
