Revelation of Twist and Reality:
The surprising facts are revealed by Chuck and he reveals that he is in fact, Dr. Sheehan. Cawley then explains that “Teddy” is Andrew Laeddis, a U.S. Marshal who is admitted at Ashecliffe for murdering his depressive wife after she drowned their three kids.
Andrew denied treatment for her wife Dolores when she burned down their apartment but instead moved his family to a house far from the town and near to a lake, where Dolores killed all their kids. Aggrieved by her actions Laeddis kills her and he turns insane.
Andrew’s delusions are a result of his guilt of killing his wife and losing his children, Andrew finally recounts the truth, and doctors believe that he is in a normal state. But, Cawley recalls that he had achieved this state nine months before, but quickly Andrew again started to show schizophrenia symptoms. He warns that this will be Andrew’s last chance.
Later, Andrew sits on the hospital grounds with Sheehan. Andrew seems to be delusional again, refers to Sheehan as “Chuck” and says they must leave the island. Sheehan signals to Cawley, who orders that Andrew must be lobotomized. Andrew then asks Sheehan what would be worse “to live as a monster, or to die as a good man?” An astonished Sheehan calls Andrew “Teddy” but the latter does not respond and leaves peacefully with the officials for his operation.
