What an interesting episode and somewhat of a left turn for the series. It almost felt like a futuristic horror plot with Reese and Root being led to a small town with it's occupants kind of being brainwashed through intimidation and implants to control them. Yeah, not your typical POI story line, but it does make sense that Samaritan would use a small town, in a controlled environment to learn and study human nature for it's own benefit. The entire premise for this was of course  pursuing a lead to find Shaw. With them failing to find her and Finch more or less abandoning the idea of pursuing her any further, it forces Root to break away from the team. I'm guessing she will be on a one-woman crusade to find her. She is alive as noted by the final scene.

One bit of casting on this one caught my eye immediately and that was Maddie Corman. She was immediately recognizable in spite of her aging a great deal since I last saw her. She is best know for her roles in Some Kind of Wonderful and The Adventures of Ford Fairlane. The last things I've seen her in were Swingers and Rescue Me. I will always picture her as a kid and not the grown up she obviously is because I haven't seen her at all since those projects come out with Rescue Me being 10 years ago. Sheesh!!!!
