Before Season 1Edit
When Vic Mackey infiltrated in Mrs. Park's sex club with Ted, he told her he wanted to watch first. She then led them to a room where Sun-Lee started having sex with an adult man. When Mackey got out, he got a warrant to intervene in the club. During the intervention, he told someone to take Sun-Lee to the Barn.
Mackey then sat down with Sun-Lee and offered to play cards with her, while he asked her for information on Mrs. Park and whoever had gotten her in the business. After their case went out of leads, Mackey informed her that he had called INS so she could be taken back to Korea. Sun-Lee didn't want to leave, but ultimately accepted.
