In the book, The Grady Twins are not twins but are eight and ten and described by Bill Watson as “cute as buttons”. They did not make an appearance but are mentioned and referenced several times and almost certainly haunt the Overlook Hotel, most likely now evil.
The Shining (1980)
The Twins make a larger and more prominent appearance in the 1980 adaptation. Whilst they are commonly referred to as "The Grady Twins", the Grady daughters were 8 and 10, as referred to by Stuart Ullman. The "Twins" therefore are not the Grady daughters, but other victims of another attrocity. They are seen for the first time when Danny Torrance passes out when he has a vision. They are seen a second time on Closing Day while Danny is in The Games Room while his parents tour the hotel with Ullman and Watson. They stare at Danny before walking out of the room, hand in hand. They are seen again in a brief vision when Danny attempts to enter Room 237. Eventually, Danny encounters them in a hallway on his tricycle. They say hello and ask Danny to come and play with them, to which Danny has visions of their corpses in the same hallway, their blood splattered everywhere on the walls and floor and an axe lying on the ground. Danny covers his eyes and when uncovering them, they are gone. They do not appear again.
