Fringe-Season 2, Episode 10

At the Hennington Mental Health Institute in Boston, a man is examining a patient, Joseph Slater, and asking him to identify a girl in a red dress that he can visualize with flowers in her hair. As Slater provides more detail, the man cuts open the back of Slater's head and removes a small white object and places it in a container. As the man starts to close up Slater's skull, his assistant gets a call. Outside, the Hybrid leader, Smith, calls to warn them they have activity. The assistant looks out and sees an orderly approach and shoots him as he calls in an alert. He and his leader have no choice but to leave, with Slater's skull still open. The leader apologizes to Slater for leaving his skull open and they drive away as a nurse finds Slater, the back of his skull open and the skin peeled down.

The Fringe team arrives at the Hennington Institute and Dr. West informs them that Slater has been there for 14 years due to acute schizophrenia and delusions. However, after the break-in and the surgery, Slater is showing remarkable progress and there's no signs of any structural damage to his brain. Walter, clearly upset at the setting, asks to see tapes of Slater when he was a patient. They review the tapes, which show Slater talking about the girl and demanding that West bring her back. Slater doesn't recognize either man and talks of how he was suddenly free. Walter empathizes with his feelings. Once Olivia finishes questioning him, Slater's wife arrives and he goes to see her. Walter admits that Slater is lucky for having a wife who visits him, but apologizes when Peter seems concerned. Olivia asks Walter if he has any theories and he admits he hasn't but is eager to find a remedy for insanity.
