Fringe: Season 3, Episode 12

3 - 12: Concentrate and Ask Again

A biological attack leaves a man dead, with no bones in his body. Fearing the start of a larger incident, they track one culprit but he is hit by a car and falls into a coma. Walter suggests using Simon (Omid Abtahi), an undocumented Cortexiphan patient with uncontrollable telepathic abilities, to read his mind to identify other targets. Olivia is able to coax Simon to help when he discovers he cannot read her mind as a fellow Cortexiphan patient. Simon helps to track down and stop two other ex-enlisted men who were part of "Project Jellyfish", a biological agent that would disintegrate skeletons; though the men were immune, their children were stillborn due to the agent, and are seeking revenge. After completing the case, Simon gives Olivia a note, revealing Peter's thoughts are still with Fauxlivia. Meanwhile, Nina Sharp has discovered that Sam Weiss is the author of several books of the First People. Sam tells Nina that Peter's deposition towards Olivia or Fauxlivia will determine which universe will survive when the machine is activated.
