S3, E18: Sully's wife has suddenly and inexplicably left him. Distraught and bitter, Sully confronts a priest, Father Romero (GIANCARLO ESPOSITO - "Homicide: Life on the Street"), and recalls an upsetting event involving Romero. After saving the life of Manuel Velez (ALBERTO VASQUEZ), a hero who rescued a child from a fire before almost succumbing to the smoke, Sully discovers that Velez is a fugitive being pursued by a ruthless bounty hunter, Bill Stram (DEAN WINTERS - "Oz"). Realizing that Velez is a good husband and father who has reformed his life since escaping justice, Sully tries to protect him from Stram. But during a gun battle, Sully accidentally kills Velez instead of Stram. Feeling guilty for many reasons--the failure of his own marriage, the death of Velez, the near-fatal wounding of Davis in a recent incident--Sully confesses that he has no faith in God. Romero persuades Sully to continue striving to improve the world through his work.
