JACK (SARCASTICALLY) "See, it's okay. He saw on the television".
Jack seethes during the conversation, barely containing his contempt for Wendy and Danny. He has just removed Danny from his regular life and schooling for 6 months so he can write a book and advance his own career. Later he will become THIS ANGRY at Wendy for simply suggesting they leave a hotel where they are alone and Danny has just been the victim of an attempted strangling.
Jack's unconscious harbors utopian desires for escape from repression, family responsibilities, and the constraints of polite behavior which induce the curtailment of urges. For example, in the HAUNTED BAR, Jack, who has promised to refrain from drinking and who clearly has money worries, is able to drink without paying. the double nature of the unconscious, as a site of both utopian and fearful desires, is signaled in the green bathroom fantasy, when a beautiful, naked woman Jack embraces suddenly turns into an ulcerous old hag. Descent into the unconscious permits a liberation from restraint, but it also is represented as a potentially dangerous pathway that unleashes repressed horrors - in this case, the fear of woman's sexuality.
Danny says that he is hungry, which is followed by a conversation about cannibalism and THE DONNER PARTY. Very soon they will meet a CHEF and Wendy and Danny will be shown through an oversized industrial kitchen, fridge, and pantry - and in response to this tour Wendy will REFERENCE another tale of cannibilism. They will be reassured by him that 'they won't have to worry about food.' Later in the movie in two instances Wendy will bring Jack food, eggs and later a snack, before locking him in a pantry full of food (some of which he EATS). Once at the hotel only Jack (EGGS) and Danny (ICE CREAM) will be seen eating.
