How we cite our quotes: All quotations are from Star Wars: The Empire Strikes Back.
Quote #4
HAN: I must have hit pretty close to the mark to get her all riled up like that, huh, kid?
LEIA: Why, I guess you don't know everything about women yet.
[Leia kisses Luke]
First off, we have to throw out the obligatory "Gross! Incest!" even though by all accounts George Lucas hadn't decided that Luke and Leia were siblings by the time of Empire's release. Second, this is the most blatant case of a lady protesting too much that we've ever seen.
Quote #5
LEIA: Why are you still here?
HAN: I heard the command center had been hit.
LEIA: You got your clearance to leave.
HAN: Don't worry. I'll leave. First I'm going to get you to your ship.
Besides showing Leia's dedication to the Rebel cause, this exchange shows Han's dedication to Leia. He might turn off his communicator when she gets on his nerves, or get cranky when she doesn't give him attention, but he'll always have her back when the chips are down.
Quote #6
HAN: You like me because I'm a scoundrel. There aren't enough scoundrels in your life.
LEIA: I happen to like nice men.
HAN: I'm a nice man.
Leia is a princess, so she spends most of her life with political big-wigs and other Very Serious People. In other words, she doesn't know anyone like Han. Although this might make her hesitant at times, it's the same thing that drew her to him in the first place.
