Dr. Walter Bishop: And you look different too, somehow. That smile. Have they altered your medication? Wouldn't surprise me. These medieval quacks are more proficient at phrenology than psychopharmacology

One of the Best and Most Mysterious Episodes
24 September 2016 | by claudio_carvalhoSee all my reviews

While driving home in a rainy night with his son Ben, Andrew Stockton stops his car to help a woman to call the tow truck. He decides to inspect the engine and when he opens the hood, he sees red and green lights blinking on the engine. He enters in a hypnotic trance and awakes with the tow truck driver, finding that Ben was kidnapped. Agent Dunham learns that a couple of talented men have been abducted in the past and returned completely insane and the boy is a musical genius. Dr. Walter Bishop recalls that the inmate Dashiell Kim in Saint Claire had had the same bad experience and killed his beloved wife later. Olivia tries to visit Dashell, but Dr. Sumner does not allow her to go since she is a stranger to him. But he accepts that Dr. Bishop meets Dashiell. Will the scientist accept to return to Saint Claire to save the boy?

"The Equation" is one of the best and most mysterious episodes of "Fringe". Unfortunately it is not disclosed the big picture of the scheme. Indeed the conclusion is deceptive. John Noble has another excellent performance. My vote is nine.
