The "investigation" is an elaborate role-play to regain his true persona. Overwhelmed by his sudden recall, Andrew faints. Awakening later, Andrew calmly recounts the truth, satisfying the doctors that he is lucid. Cawley notes that they had achieved this state nine months before, but that Andrew had quickly regressed. He warns that this will be Andrew's last chance and if he lapses again he will be lobotomized due to his very violent conduct towards other patients such as Noyce, and towards the guards. Sometime later, Andrew relaxes on the hospital grounds with Sheehan. Appearing delusional, Andrew again refers to Sheehan as "Chuck" and says they must leave the island.Cawley explains that Andrew's delusion is a result of his guilt, that his migraines and hallucinations are withdrawal symptoms, and that he had created the alternate persona of Edward Daniels,[a] also a Marshal, who acted violently and espoused conspiracy theories about the facility.Andrew then asks Sheehan if it would be worse "to live as a monster, or to die as a good man?" A stunned Sheehan calls Andrew "Teddy" but the latter does not respond and leaves peacefully with the orderlies for his operation.Sheehan signals to Cawley, who orders that Andrew be lobotomized.Andrew did not seek treatment for Dolores when she burned down their apartment and instead moved his family to a lake house, where Dolores carried out the killings.
