A Thousand Cranes (S09E16)

Pratt tries to keep Gallant from overreacting when they are apprehended and questioned as possible suspects in a murderous rampage at the diner near the hospital. Lewis befriends a teenage cancer patient, Sean Simmons (Patrick Fugit), who fears he might not have long to live. Meanwhile, Carter must endure a long trip to the bus station with Abby's inquisitive mother, Maggie (recurring guest star Sally Field). He also ponders a major life-changing decision. And troubled Kovac ruminates on his tragic life when he is forced to consult a psychologist. (Warner Bros. UK)
