Luke Skywalker: You know, I think that R2 unit we bought may have been stolen.
Uncle Owen: What makes you think that?
Luke Skywalker: Well, I stumbled across a recording while I was cleaning him. He says that he belongs to someone named Obi-Wan Kenobi. I thought he might have meant old Ben. Do you know what he's talking about?
Uncle Owen: Uh-uh.
Luke Skywalker: I wonder if he's related to Ben.
Uncle Owen: That wizard is just a crazy old man. Now, tomorrow I want you to take that R2 unit to Anchorhead and have its memory erased. That'll be the end of it. It belongs to us now.
Luke Skywalker: But what if this Obi-Wan comes looking for him?
Uncle Owen: He won't. I don't think he exists anymore. He died about the same time as your father.
Luke Skywalker: He knew my father?
Uncle Owen: I told you to forget it.
