In the Pilot episode, Jarek agrees to lead a special task force to finally expose Alderman Ronin Gibbons for his graft. After a rigorous testing period, he decides to keep newcomer Caleb Evers as his partner when Caleb's instincts that about Liam Hennessey prove to be spot on. Jarek has a son and ex-wife Dina, whom he's sleeping with, despite the fact that he has a financé. Most of his life is dedicated to his job as a police detective.
