The Damage Done

S5 E5: Jack becomes fixated on using the desperate situation of Sadik Marku (recurring guest star MARK PELLEGRINO), the Albanian mob boss who had an ominous role in one of the team's previous cases, to unearth evidence against him. When Jack gets the FBI involved in the case of Sadik's missing mistress, Julia (RACHEL MINER), and their 8-year-old son, Petros (FIELD CATE), Samantha questions whether Jack is more interested in going after Sadik or finding his loved ones. During the investigation, the team learns that a neighbor saw a man throw Julia and a blanketed bundle believed to be Petros into the backseat of a car. Among the many suspects in the abduction are rival gangs and mafia members, as well as Sadik's wife.
