Frasier: I've nothing else to say. Niles, I love you. And I love Daphne. I just hope the two of you can work this thing out together.
Niles: No, wait, don't go, don't go. Help me understand, why is everyone acting like I've done something wrong? The only thing I am guilty is loving Daphne, and that's all I've ever done.
Frasier: Yes. Yes, and how did you love her? From afar. You were never in love with her, you were in love at her. Now, you've been given a chance to experience her in a real relationship and yet for some reason, you're resisting it. Rather than see her as she really is, you keep holding on to the fantasy.
Niles: No, that's not true.
Frasier: Niles, the woman gained sixty pounds, and everyone in the world saw it but you. All you ever saw was a perfect woman in a red dress.
[Niles takes a moment to process this]
Niles: Okay. If you're right - and that's a big "if" - why would I do that?
Frasier: Maybe Daphne's not the only one who's afraid she won't measure up. Maybe you're afraid, too. After all, if it turns out she's not perfect, then there's a chance things won't work out. Then not only will you lose Daphne, but you'll have wasted the last seven years of your life chasing an illusion.
