Penny for Your Thoughts sees Medium sliding into Silence of the Lambs territory, with Allison questioning a creepy doctor in prison who cut up a young girl 15 years ago.
The A-story was excellent, and didn't disappoint following the insanely gory teaser. Mark Sheppard is always dragged out to play evil psychopaths, but his presence was used well here. I also loved the idea of an "evil soul" that Allison has to battle with every once in a while, and I thought the closing moments where she was essentially shaking Walker out of Elisha featured some awesome acting work from Patricia Arquette and guest star Danielle Panabaker.
My favorite scenes were probably the interrogation between Allison and Dr Holloway, in particular how he changed accents whenever he was possessed by Walker. Walker is probably the most terrifying nemesis scene on the show so far and he becomes a recurring nightmare for Allison to investigate, making more appearances as the series goes on.
The subplot was also very effective. A simple story involving a teacher believing Ariel cheated in class, it proved how different Allison and Joe are, and it was pretty sad to see that Joe's intervention was pretty useless, as Allison proving her own "guessing" powers eventually won over the teacher's trust.
Whilst it's no classic, this is an effectively creepy episode with a sick bad guy and some unexpected twists and turns as the story goes along.
