Renton in “Date of Birth”

Eureka, what's beyond the Great Wall? Eureka: I don't know, but there's one word I know to describe it. Renton: What is it? Eureka: Future. That is what is beyond the Great Wall, Renton. Adroc said that to me. Renton: My dad did? (he is shocked as she nods her head) Wait, you mean you know all about my dad? Eureka: What's wrong? Renton: You should've told me that you knew. Eureka: About what? Renton: About my dad! Eureka: Well, I didn't think you would want to hear about him that much. Am I wrong? Renton: (he grabs her shoulders) He's my family! Geez, any human would want to hear about their family, wouldn't they? Eureka: I don't understand that, Renton! Renton: What do you mean you don't understand? It's the natural way for humans to think! What's wrong with you?! Eureka: What's wrong...is that I'm not human. (she runs away)
