In Which We Meet Mr. Jones (S01E07)

Every second counts when a strange, almost-otherworldly parasite mysteriously attaches itself to the internal organs of a dying FBI agent. With a life on the line and strong suspicions of a "Pattern" connection, Agent Dunham rushes to Germany to meet with an imprisoned man who reveals disconcerting details of a much larger threat. Meanwhile, Peter and Walter attempt to help Olivia by tapping into a dead man's brainwaves. (Warner Bros. UK)
