Set entirely in a prison setting, "Twenty Vicodin" is immediately reminiscent of the sixth season premiere ""Broken," set entirely in a psych hospital. The comparisons end there, however. Beyond the expect prison trimmings, "Twenty Vicodin" is a typical House episode, a medical procedural in prison.
It plays out as one may expect and nothing has really changed. House is still House, perceptive as ever. He's actually decided to stop doing medicine, to study physics instead, but obviously that's not going to happen. Another medical mystery draws him into this world and that's that. Then there's the pretty, bright-eyed female doctor, played by Odette Yustman. She doesn't like working at the hospital--until House shows up and does his thing.
