Frasier: Well, that is very impressive, Dr. Sternin. But I too happen to be a psychiatrist. Let me tell you what actually transpired. This was a passive-aggressive manifestation of your deep resentments towards me. Niles, you were punishing me for my notoriety. [to Lilith] You, for my successful adjustment after our divorce. It is this shared bond that brought the two of you to your palace of sweet revenge.

Frasier: I have a right to... Why am I defending myself?
Niles: If you ask me, you are both off the mark. Last night was about two people, ruled by very powerful superegos, tortured by them, who found a chance, however misguided, to break through and rediscover their ids together. Call me an old softy, but that's how I see it.
