1. (Quilty frivolously answers with a grin on his face: "Lo-li-tah. Yeah, yeah. I remember that name, all right. Maybe she made some telephone calls. Who cares?" )

2. (Humbert is dismayed by Charlotte's comment that "tonight's the night! Well, Lolita told me that she's positive Kenny's gonna ask her to go steady tonight." )

Quilty: (...) Yes, really great fun. Listen, listen, din, din you have a dawda (daughter)? Din you have a dawda with a lovely name? Yeah, a lovely, what was it now, a lovely lyrical lilting name like, uh, uh...
Charlotte: Lo-li-ta.
