That's Not My Penguin

The episode opens with Gabriel Wyath (Billy Lush) in a psychiatric ward after blowing up a government building. There are doctors who are taking notes and comparing Wyath's behavior to that of Michael Britten. The doctor's note that the two are sharing signs of disorganization, having odd behavior, and suffering from a sleeping disorder. Later, in the "green reality" (where Rex is alive, and Hannah is dead from the crash) Michael forgets to sign a permission form for a field trip. He goes to work, and asks Efrem Vega (Wilmer Valderrama) if the prints came back. Since he is in the "green reality", Efrem is confused, because he is not his partner in this world. Michael suddenly realizes that he is in the "green reality". Later, Bird is bragging about his astronaut bed, when Dr. Wild comes to Michael's desk, and asks for his ring. In the "red reality" (where Hannah is alive, and Rex is dead from the crash), Michael goes to work, and is called in for a hospital hostage situation. Gabriel Wyath (Billy Lush) is the one causing the situation. He demands to see his sister Christie. However, she was murdered in a dispute with an ex-boyfriend. Gabriel created a separate world where she was not murdered, but rather kidnapped by Dr. Wild.

Later, Dr. Lee explains what they are dealing with. Gabriel allows Michael to come in the hospital, but nobody else. Michael enters the building and realizes that he has a "dead man switch", meaning that if Wyath is shot, then the whole building will blow up. Gabriel goes up near the window to handle a man who is screaming, and the police are prepared to shoot him. However, to prevent Gabriel from using his switch, Michael jumps at him, causing him to divert his path. Gabriel knocks him out, and shortly after injects him with ketamine. Michael suddenly wakes up in his "green reality". Michael is looking for a ring, which is Dr. Wild's. He sees a hallucination of a penguin, caused by the drugs. The penguin tells him that Rex has the ring. He calls him down, and Rex reveals that he stole it for his girlfriend, Emma (Daniela Bobadilla). Michael meets Emma and gets the ring back. Dr. Evans (Cherry Jones) claims that he is "having a nightmare about madness". He wakes up in the "red reality" and sees Dr. Lee helping him. The police are coming in to shoot him. Michael quickly phones and tells them to stop, due to the "dead man switch". Gabriel and Michael talk about Gabriel's two reality life. This makes Michael think about his life. Shortly later, Michael and Dr. Evans are talking about his mind. He thinks about his life and tells her that he is okay. During a subsequent discussion, he finds out that Dr. Lee was not really inside his mind; he was actually helping himself.[1]
