This episode shares several similarities with the 1st season episode "The Show Where Lilith Comes Back". These similarities include:
- A Crane brother sleeping with Lilith.
- Lilith ordering poached eggs from room service and having the order made incorrectly.
- The respective Crane brother frantically listing all the reasons why sleeping with Lilith was a mistake after she said "It's a mistake" referring to her eggs
- The respective Crane brother comforting Lilith in the mirror after her emotional breakdown. Both Frasier and Niles start off saying "Do you know what I see? I see a beautiful woman..."
Frasier's shoes appear and disappear from his feet while he his in the motel room. They appear when he sits on the chair, but are gone when he walks to the chair on the other side of the room. There you see his shoes on the floor, and he puts them on.
Seeing as Niles is a Jungian, it is unlikely that he would use Freud's ID and Super Ego to explain his sleeping with Lilith, however he may have been trying to play to Frasier's good side, as Frasier is a Freudian.
Frasier : (About Lilith) Her husband has left her and get this. For a man.
Niles: Damn. I owe Dad five dollars.
Frasier: Speaking of buns I could do without, Lilith is back!
Niles: Oh, that explains why blood was pouring from all my faucets this morning.
Niles: Now I remember ordering this, it's the breakfast I always have after a night of passion.
Lilith: Eggs Benedict? That's very rich.
Niles: I only have it once a year.
(Lilith is wearing a revealing new cocktail dress that has more than attracted Frasier's attention)
Lilith: It's from a new couture line called "encore".
Frasier: Oh, well... bravo. I can almost feel the curtain rising.
Roz: Hey, that's rough, leaving you for another man. Did you have any idea?
Lilith: No, none at all. Stan was a contractor we had hired to extend our master bedroom. It's ironic, isn't it? No sooner do I get the closet of my dreams than my husband comes out of it.
The scene title "A Long Night's Journey Into Day" is reference to the play "A Long Day's Journey Into Night". The play is written by Eugene O'Neill, who is mentioned earlier in the episode.
