Beauty and the Beast

While walking in the world Above, Vincent recognizes Rolly, a teenage musical prodigy and ex-tunnel dweller who is now a junkie.

In a moment of profound despair, Vincent undergoes his own It's a Wonderful Life (1946) experience and sees what would have happened if he had died as a baby.

A Russian sailor escapes to the tunnels only to bring a plague upon the people in the Underworld. It is up to Catherine, Vincent, Father, and everybody to help save their world.

When the tunnel world is having an annual event, Paracelcus makes plans to crash the event and do something. When all of the participants arrive, including some friends from the surface, things seem to be OK until Narcisa shows up. It seems she had encountered Paracelcus earlier who had in his possession someone's head who then tried to kill her. They assume Paracelcus is there in disguise. Catherine and Vincent deduce it must be someone from the surface but there are only three whom he knew before he was banished so they try to figure out who could it be.

With Catherine's help, a pregnant teenage hooker is welcomed into the tunnels. Complications arise when she falls in love with Vincent.
