How we cite our quotes: All quotations are from Star Wars: A New Hope.
Quote #4
BEN: I suggest you try it again, Luke. This time, let go your conscious self and act on instinct.
LUKE: With the blast shield down, I can't even see. How am I supposed to fight?
BEN: Your eyes can deceive you. Don't trust them. Stretch out with your feelings.
Star Wars loves to play the destiny card, but it just doesn't give its characters their dreams. That would make for a boring movie. Instead, they have to work for them as evident by Luke having to train to be a Jedi.
Quote #5
LUKE: Uh. 3PO, hand me those binders there, will you? Okay. Now… I'm gonna put these on you.
CHEWBACCA: Grawh!
LUKE: Okay. Han, you—you put those on.
HAN: Don't worry, Chewie. I think I know what he has in mind.
Chewbacca isn't a chatty Cathy, but we get a sense of his hopes through the growls and roars. He is fiercely loyal to Han, and he wants both of them to maintain their freedom. This scene tells both the viewer—and Luke—that fact loud and clear.
Quote #6
VADER: Obi-Wan is here. The Force is with him.
TARKIN: If you're right, he must not be allowed to escape.
VADER: Escape is not his plan. I must face him alone.
Vader is a basic sci-fi Black Knight, but we do get a sense that he dreams of being the most powerful bloke on the block. His desire to kill Obi-Wan and prove he is the master shows us this.
