Honor Bound

S4, E5: The team searches for 25-year-old Korean-American Wendy Kim (Nicole Bilderback), who vanishes after a fight with her new boyfriend during her night shift at her parents' deli. The investigation uncovers that Wendy felt stifled by the expectations of her traditional immigrant parents and her custom-bound elder brother, who are ashamed that she ended her engagement to a man from their community. Initially, the team wonders if she's the casualty of a store robbery, if she's been victimized by her new boyfriend or spurned ex-fiancé, or if she simply ran away with the night's cash to start a new life for herself. Numerous additional suspects surface when the team discovers, to the surprise of Wendy's family, that she was also an extremely active member in an Internet dating service.
