Enrico: It’s hysterical, is what it is…that one of our own people could be so weak…

Yumiko: Father…
Enrico: No, don’t worry, Yumiko. It’s okay.
I had Heinkel shoot the guy, so I feel a lot better now.
Yumiko: …oh.
Integra: And as for you–
Kim: That was amazing! You guys are some kind of superheroes, right? And you fight vampires! Vampires really exist! And suck blood, and everything! But I’ve never read about anything like you before. What a story this will make!
Integra: You’re not going to make any stories out of this, Kim. Sailor Regenerator? The film.
Kim: Wait a minute…you know my name? Do I know you?
Integra: No.
Kim: That scar on her face…those glasses…she’s Alex Anderson, isn’t she?
Integra (thinking): Drat.
