imagination. In these visions, Escobar appears with his original face. He appeared in the season two finale, in which he urges Sean to kill the Carver. Escobar was absent from season three, but finally returned in the fourth episode of the fourth season as Sean's marijuana brownie-induced hallucination. He played the evil side of Sean's conscience, while Megan O'Hara played the good side; Escobar encouraged Sean to cheat on his wife, Julia, while Megan encouraged him to resist the urge to cheat. Escobar again appeared as a hallucination in the sixth episode, urging Sean to kill Monica Wilder, the night nurse with whom he had a brief affair. While in prison, Escobar planned an escape which involved McNamara/Troy's former rival surgeon (and his own personal sex slave) Merrill Bobolit. He set himself on fire, and convinced prison authorities his injuries were inflicted by other prisoners, who thought he was a child molester. He then had Merill contact Christian and Sean, forcing them to perform his reconstructive surgery. While recovering from his surgery, he had Alejandro, one of his henchman and the brother of Silvio, pose as a nurse. Alejandro snuck a gun to Escobar, who used it to kill several guards and escape. Escobar then met Sean in his home. At first, Sean thought Escobar was a figment of his imagination, but then realized he was actually there. Escobar then told Sean that he needed to tell Julia about his affair, as the truth would set him free. He also told Sean that they were now even, meaning Sean and Christian were free of their "obligation" to him. Before leaving, he told Sean that the last bit of evidence involving the "swamp" was in his living room. Sean then found Alejandro's body, and confessed his affair to Julia. In season four, it was revealed that Escobar was behind the organ trafficking ring in which McNamara/Troy's business partner Michelle Landau and the mysterious James LeBeau were involved. Following James's suicide, Escobar visits Michelle, and demands she take over the operation. He later bargains with Michelle, telling her that he will let her leave his operation unharmed, granted she convinces her fiancée, Christian, to perform reconstructive surgery on his wife. Escobar's wife, Gala, was tortured and mutilated by the family of the woman who Escobar forced to smuggle heroin. Sean and Christian reluctantly agree to perform the operation on her. Michelle assists
