[Chizuru doesn't think things through either... In this twisted state, she would be thrilled if someone offered to kill her enemies for her. She wants to be protected as much as she wants to protect her brother. It doesn't even occur to her that he might not want her to bloody her hands until his brow furrows.]

You're my brother, so of course I'd be concerned about you... you don't have to apologize for that.

[She brings up a hand so that her fingertips can brush against his cheek in a fleeting, affectionate gesture, but then she's seized by a sudden fear that his apology and the furrowing of his brows means he disapproves, that he remembers the sort of person he once was and has equated that with her now. If he doesn't want anything to do with his old self, how can he want anything to do with her?]

I really, really love you... you believe me, right? You believe that I could never, ever lie about that?

[She'll lie about pretty much anything else, but... not that. Never that.]
