Hm, well, the line could be "Your going to pay for threatening the queen.". Since, I see that the trial scene is going to be in it fits on two aspects. One he was in the trial and, could have stopped the sentancing. Two he sent two ... things to shoot at thier ship thus causing her to fall overboard. Three, it isn't out of character and, he isn't revealing anything to Obi-wan. Mabye replacing the queen with Padme would make it more personal... "Your going to pay for threatening Padme!"
