Sam feels that if he can prevent his father from leaving back in 1973 that this may solve the problem allowing him to wake up from his coma.  Sam begins to hear sounds that lead him to believe that he is waking up from his coma as he gets closer to apprehending his father.  Gene reveals that Vic is a gangster.  Sam decides to allow his father to escape rather than traumatize his family with an arrest. Memories from a young Sam involving the incident that he is only remembering now are discovered with flashbacks through the entire series.
