Something unusual.

Something eldritch.

Luke: I still can't believe Owen and Beru would lie to me.
Obi-Wan: They had to. They were protecting you... in their own unique way.
Luke: Tell me about my parents. Where are they?
Obi-Wan: Your father Anakin used his Jedi powers for his own gains. It corrupted him. He betrayed and murdered your mother, Padmé Amidala.
Obi-Wan: That was the end of our friendship. We duelled, and he fell.
Luke: Whoa, let me get this straight.
Luke: My name is Luke Amidala? You killed my father?
Obi-Wan: I was prepared to die to save the Galaxy from him.
Obi-Wan: But your mother... was an angel. She died trying to... uh, redeem Anakin.
Obi-Wan: Here, she wanted you to have these when you were old enough.
Luke: What are they?
Obi-Wan: Your mother's underwater oxygen extraction apparatus and grappling hook.
Luke: O-kaaay.
Captain Antilles: {dead} They were very special to her!
