Episode Summary from en.wikipedia.org:
Reese must protect Charlie Burton (Enrico Colantoni), a school teacher who witnessed a Russian mobster shooting an Italian-American mob lieutenant in a Brighton Beach bodega. As Reese and Burton flee the Russians and the Five Families, they stumble into territory controlled by Bulgarian mobsters. Meanwhile, Carter searches for Burton to place him in protective police custody, and in doing so, draws closer to finding Carl Elias – believed to be the illegitimate son of an aging mobster with a plan to unite the Five Families and reclaim the New York underworld from the Russians. Cut off from Finch as he tries to evade the Russians and the Bulgarians, Reese comes to realize that Charlie is Elias. Elias thanks Reese for saving him, but warns him to not interfere with his future goals or face unpleasant consequences, leaving Reese feeling guilty that other people will suffer because he saved Elias’ life.
