The Rescue is a noble adventure paradigm. And all you need to do to set it up is have one of the heroes be silly enough to get captured. It virtually writes itself!
Leia: We can still save Han! Come on, Chewie!
C-3PO: I am completely in favour of risking our lives to rescue Han!
Chewbacca: I should like to rescue him since he has long been my travelling companion. But what precisely is your reason?
Leia: Come on, don't make me spell it out.
Chewbacca: I'd like to know where you stand.
Leia: He's an asset to the Rebellion. He may talk big about betraying us, but really, when has that ever worked out for him?
Leia: And he knows stuff about the Empire that our spies can only dream of getting!
Chewbacca: Oh really? That's what you're going with?
Leia: I love him!
Chewbacca: I know.
Chewbacca: I just wanted to make you say it.
