Why not?! Luke, if you weren't real, would you be talking to me right now? If you really weren't real, would you be able to think and feel like you're doing right now? You're as real as I am, so don't you dare say otherwise! You bleed and cry and sleep and dream just like I do, right?!

...I don't know what it means to be a replica thing or whatever, and I honestly don't care if you are. You'll always be the person I know and care about very much. But I won't let you put yourself down like this! You mean more to me than that, and I really hope you understand.

[She hates raising her voice, but what he was saying sounded just plain crazy. How could he not be real just because he was some replica. What does it mean to be 'real', then? ...Is that why he was asking about souls? Luke, you are an idiot.]
