Question: why was jack torrance in the picture at the end of the shining?
Answer: Stanley Kubrick said, “The ballroom photograph at the very end suggests the reincarnation of Jack.” That means that Jack Torrance is the reincarnation of a guest or someone on staff at the Overlook in 1921. ... The Overlook seems to have the power to recall reincarnated versions of its past guests and employees.
