I really wish IMDb didn't impose a six hundred character minimum on reviews. They weren't used to, and it makes it really difficult to make pithy comments about an episode or performance, however well deserved. In this episode, for me the standout performance came from Amy Morton. We see her here exerting her authority as Erin's boss, before transferring to Dick Wolf's Chicago franchise. Her stellar continuing performance there as Trudy Platt surely marks her as one of the world's great actors - she truly commands her station, as one of the characters in that series says, and holds that character fast.
