Not wanting to put the Tunnel World in further danger, Vincent decides to leave the tunnels and with the death of Snow, Gabriel plots for Vincent's demise. Meanwhile, Elliot is on the verge of financial ruin and Gabriel promises him he will restore his empire if Elliot were to betray Vincent. Diana reveals what she has found to Joe and later she stakes out Catherine's grave where she encounters Vincent who is in critical condition following an explosion on the docks that may have cost Elliot his life.

In the aftermath of the boat explosion that most likely killed Elliot, Diana is shocked when she encounters a wounded Vincent who collapses on Catherine's grave. She takes him back to her apartment where she nurses him back to health and they soon connect, with Vincent telling her about Gabriel. Meanwhile, Father comes above fearing Vincent has died in the explosion and seeks information from Joe.

After Vincent entrusts Snow's ring to Diana, she quickly discovers Gabriel's henchman have targeted her and soon kidnap her and take her to Gabriel. Meanwhile, Vincent's son has fallen ill and Gabriel convinces Diana to have Vincent surrender to him.

With Vincent caged, Gabriel allows him to see his infant son who suddenly begins to make a miraculous recovery. Meanwhile, Diana is pursued once again by Gabriel's henchman but she manages to contact Joe with a lead that ultimately leads them to Gabriel's home in Staten Island. However, they may just be too late, as Gabriel has decided to kill the baby.

Rolley is shot while trying to rob a liquor store and takes refuge in the tunnels. This brings his heroin addiction to the forefront and Vincent vows to do his best to help Rolley which leads to a fiery encounter at a drug house that unknown to Vincent is run by Gabriel.

A woman whom Father knows returns to the city. She asks him to join her and he considers it. At the same time Diana is working on a murder. And it turns that the victim is someone Father knows.

Upon returning to "The World Below" upon the knowledge of some of ex-tunnel inhabitants being murdered, Father encounters Gregory Coyle who seeks revenge for the death of his father by cave-in 20 years ago.
