Quote from Niles in The Kid
Daphne: So, how did the father take it? [to Frasier] Don't worry, she brought it up. Roz: Actually, he took it really well. He's not going to be that involved, though. He moved to Cairo. Niles: Where would he have moved to if he'd taken it badly? Roz: No, he's working in Cairo on a project as an archaeologist.
