The Client - Season 1 Episode 9 Child's Play

Reggie attempts to help a young boy, Ryan Nichols, find his father, Dewey, who was in the witness protection program, so that Dewey can donate bone marrow for the boy's severely ailing younger sister. Reggie and Foltrigg were responsible for convincing the missing Dewey to testify against two notorious gangsters who were sent to prison as a result. They then helped him and his family hide in order to avoid retaliation. But when he lost his job and couldn't get another, Dewey fled, leaving his family with no way to find him. Clint and Reggie locate him, but a hit man takes Dewey hostage. Foltrigg arrives and saves him.
