Season 1, Episode 7:

In Which We Meet Mr. Jones
A Fringe Division agent, Mitchell Loeb, is infected with a deadly parasite that grows like a plant around his internal organs. After finding a link between Loeb's latest case -- investigating a potential second mole in the FBI -- and a scientific terrorist organisation called ZFT, Olivia travels to Hamburg to speak with a biochemical terrorist named David Robert Jones, a known ZFT member who has been captured by the Germans and might have the solution to stopping the parasite. Jones claims he knows a cure, but first he wants to ask a question of an associate named Smith in the United States. Broyles arranges a raid, but Smith fires on the FBI agents and is gunned down.

However, Walter has a method of tapping into Smith's mind and interrogating him that will work even though he's dead. They hook Peter up to Smith and a machine so that when Olivia relays Jones' question -- "Where does the Gentleman live?" -- over the phone, Peter is able to interpret the response "Little Hill". Satisfied, Jones gives Olivia the formula for a chemical that will stop the parasite that saves Loeb in the nick of time. However, unbeknownst to the team, Loeb and his wife are both working with Jones, and the whole incident was orchestrated to learn the information from Smith.
