Cause and Effect

S1, E2: Marcus, a former patient of Dr. Rosen's (David Strathairn) with the ability to set off a chain reaction of events with a predetermined outcome, escapes from Binghamton, a facility designed to detain and train Alphas. His escape causes Rosen to reexamine his tenuous relationship with the government, while he's being forced to get acquainted with his new Department of Defense liaison, Agent Sullivan (guest star Valerie Cruz). Meanwhile the rest of the team continues to balance their personal lives while continuing to work with Rosen.
