Jack is to become an infinite blankness in servitude to a nightmare of spiritual control carved into two known identities. The name he is called by, Jack, is about to be shared, which is why the hotel addresses him only by his last name, Mr. Torrance (Jack and Dad are clearer descriptions). The hotel gets the use of his name, like a marriage.

Here next to the bathroom worn by the man on the left is the final white corsage in a string of them that starts on Jack's walk to the bar and continues all the way here.
