Here's my recreation of my copy of the book. Remember the asterisk indicates work by Huyck and Katz:
Luke sits in the co-pilot's seat. He and Han stare out at the vast blackness of space.
*LUKE: So...What do you think of her, Han?
*HAN: I'm trying not to, kid.
*LUKE: (Under his breath) Good ...
HAN: Still, she's got a lot of spirit. I don't know, do you think it's possible for a princess and a guy like me ...
LUKE: No.
Luke says it with finality and looks away. Han smiles at young Luke's jealousy. They both stare at the stars and think about it.
...Threepio intercedes on behalf of his small companion and begins to argue with the huge wookiee.
THREEPIO: (To Chewie) He made a fair move. Screaming about it can't help you.
HAN: (To Threepio) Let him have it. It's not wise to upset a wookiee.
THREEPIO: But, sir, no one worries about upsetting a droid.
*HAN: That's because a droid doesn't rip peoples arms out of their sockets when they lose ... wookiees have been known to do that.
*THREEPIO: I see your point. (To Artoo) I suggest a new strategy, Artoo. Let ...the wookiee ... win.
Tobar, I think you are cheating!
