There's no translation there. That sentence comes from the raw.
And please, pay more attention to the character expression.
Leonid complimented her with a plain tone (with no emotion) as if he didn't mean it.
Oh, sorry, i didn't mean that the sentence on page 18 was your mistranslation. Just an unusual choice on mangaka's part (Zabeth seems to be a diminutive of Lisabé, which is Norman equivalent to Elizabeth).
As for Leonid, eh,.. i don't know, he delivered that line the way i expected him to, so it didn't strike me as shocking, at least not to extent other characters showed.
