[Don't talk to your uncle like that, mister. Oh, who am I kidding, everyone in the Matou family talks to him that way.]

No, I didn't know that. I'm not a character. I'm a person. So is Sakura. I know she's not your blood relative...

[He trails off. If Shinji doesn't believe he's even a person, then explaining the family situation might not serve any purpose.]

But she's still your sister. [Although what Kariya wants to do would mean that they aren't brother and sister anymore. Still, he should respect Sakura.] Or in my world, she is, now. And I am your uncle.

[It could be said that stubbornness ran in the Matou family.]

You shouldn't be alone here. It's dangerous.
