YOU'RE MONEY'S NO GOOD HERE, MR. TORRANCE

Time for a recap, don't you think?

1. Danny Torrance is a six years-old boy living with his mother Wendy and his father Jack. Unfortunately the Torrances are a dysfunctional family: Jack is a violent alcoholic who just can't keep a job, and his career as a writer is going nowhere fast.
2. However, Danny is not an ordinary boy. He has an innate psychic ability called "the shining". The "shining" allows Danny to see the past, the future, and establish telepathic contact with other "shiners" (like, for instance, Hallorann and his father). 
3. Danny is much too young and immature to deal with this ability, so his subconscious has created Tony, a little boy who lives in his mouth. It's Tony who apparently decides when and how Danny "shines". King's novel establishes that Tony is not a little boy at all, but a manifestation of Danny's future, grown up, self. 
4. Tony understands that Jack will, one day, hurt Wendy and Danny for good. Jack has grown resentful of his family over the years, and believe they have fucked up his life. Divorce is out of the question. While Wendy is a good mother who tries very hard to take care of her son, she is too weak-willed to leave Jack once and for all. 
5. So, Jack has to go. Fortunately, fate provides Tony with the perfect opportunity. 
6. Jack is about to land a job as the winter caretaker of the Overlook Hotel, perched on top of the Colorado Rockies. For Jack and Wendy this is a godsend. Jack thinks he may finally complete a writing project, and Wendy welcomes her husband's new job as a stabilizing effect on his mood. 
7. However, the Overlook is haunted. Several people have died already within its walls, and the whole place reeks of malevolence. Sending Danny up there with a half-crazy Dad and mousy Mother is a perfect storm in the making. On the other hand...
8. It may also be the perfect way to get rid of Jack. Tony surmises that the Overlook will use Jack to hurt Wendy and Danny. Logical, since Jack already hates his wife and son. Furthermore Tony understands one crucial element: Jack also has the "shining", however he does not know it, nor does he understand the implication of such a gift.  While up there, Tony can protect Danny psychically, while his mother will care for him physically. Adding Danny's natural calm and unflappability, Tony figures that Danny will not be in any real danger at the Overlook. Hallorann, the Overlook's chef, is an unexpected yet welcomed ally: Hallorann can "shine" as well and knows about the evil of the Overlook. It's risky, but the risks are well within the bound of acceptability, 
9. So there we are, Danny subconsciously sets a trap for his unworthy father. All he has to do is keep out of the way when the shit hits the fan, stay calm and remain one step ahead of the Overlook ghosts.

All very well, but can I prove any of this? as Wendy would say "let's just wait and see, we're all going to have a real good time...."
