A violent patient admitted to Wakefield proves too difficult for Rohan (Pacharo Mzembe) to handle in the new "Episode 7." Meanwhile, the conflict between Nik and Kareena (Rudi Dharmalingam, Geraldine Hakewill) finally erupts, forcing Kareena to admit that she's becoming increasingly worried about Nik's mental state. Later, Nik realizes the details of his brother's death aren't adding up in a credible way.
