Occasionally, the series does an episode about different cultures and I liked this one, the brother/sister story was well written.
Ken Nakamura is in a horrible position – having solely raised his baby sister, she goes to America where he cannot protect her. She turns up dead and not only does he have to deal with her murder, but also the things she was involved in, such as being a model. Satchi was killed because of what her roommate was involved in, she was innocent. Ken will have to live with the feeling that he failed her, however unreasonable.
Brennan comments how alone she is, the writers seem to have utterly abandoned Max and Russ. I liked the sense of growing closeness they had been creating between Brennan and her brother. However, I am relieved they've abandoned Max, the writers had destroyed the interesting story from season 3.
A very good episode, interesting and moving.
