Kid, I’ve flown from one side of this galaxy to the other. I’ve seen a lot of strange stuff, but I’ve never seen anything to make me believe there’s one all-powerful Force controlling everything. There’s no mystical energy field that controls my destiny. It’s all a lot of simple tricks and nonsense.

The more you tighten your grip, Tarkin, the more star systems will slip through your fingers. I call it luck. Ye-ha! I call it luck.

I suggest you try it again, Luke. This time, let go your conscious self and act on instinct. I want to come with you to Alderaan. There’s nothing for me here now. I want to learn the ways of the Force and be a Jedi, like my father before me.

In my experience, there is no such thing as luck.

I can’t get involved! I’ve got work to do! It’s not that I like the Empire, I hate it, but there’s nothing I can do about it right now. It’s such a long way from here. Obi-Wan is here. The Force is with him.

  1. Red Five standing by.
  2. I call it luck.
  3. She must have hidden the plans in the escape pod. Send a detachment down to retrieve them, and see to it personally, Commander. There’ll be no one to stop us this time!

Hey, Luke! May the Force be with you.

What good is a reward if you ain’t around to use it? Besides, attacking that battle station ain’t my idea of courage. It’s more like…suicide. Your eyes can deceive you. Don’t trust them. The Force is strong with this one. I have you now.

  • I suggest you try it again, Luke. This time, let go your conscious self and act on instinct.
  • Partially, but it also obeys your commands.

Dantooine. They’re on Dantooine. Oh God, my uncle. How am I ever gonna explain this? Hey, Luke! May the Force be with you. No! Alderaan is peaceful. We have no weapons. You can’t possibly… I suggest you try it again, Luke. This time, let go your conscious self and act on instinct.

What?! I’m trying not to, kid. Still, she’s got a lot of spirit. I don’t know, what do you think? Don’t act so surprised, Your Highness. You weren’t on any mercy mission this time. Several transmissions were beamed to this ship by Rebel spies. I want to know what happened to the plans they sent you.
