They walk in silence into complete darkness, except for the BEAM from Buddy's flashlight. A FIGURE, covered head to toe in black cloth, passes through the light, slinking along the tunnel wall toward them. Buddy hisses over his shoulder to Napolitano --
Napolitano relocates as the Figure moves on.
They walk some more in near-total darkness. Then --
He LAUGHS. Napolitano, feeling ridiculous, pushes the hood back off his face.
The path forks in two directions. A low section of wall hangs over one pathway.
As Napolitano ducks, he places his hand on the surface above. It's wet -- his hand slides off and he momentarily loses his balance.
