if you ever get another chance of redubbing that first scene this is the kind of dialog i thought of on my spare time that might fix the shitty dialog (mesa) and make jar jar a lot more tolerable

jarjar: you saved my life, thank you

quigon: you almost got us killed are you brainless?

jarjar: (bragging like it's a cool thing) well i speak (or) i speak don't i?

quigon: the ability to speak does not make you intelligent now go on

jarjar: no way i'm staying, sticking with you as a humble servant is a whole lot safer.

quigon: that wont be necessary

jarjar: well my instinct tells me otherwise

(battle droid fight)

jarjar: that's twice you saved me

obiwan: whose this?

quigon: a local we have to move before more show up

jarjar: more? hey wait a minute!

that's the idea i have so far. as you can see i just changed the dialog so it isn't that far off from the original dialog and with a good voice actor with the right accent or no accent, jarjar might come out a whole lot better character than he is now.
