The reluctant Fat Goose is eventually found and forced by Lau's partner Pitt to be a witness with promises of police protection. En route to the station, God of Hell tries to kill the two and, although captured, is freed the same day on bail. Fat Goose receives death threats, has his apartment firebombed and is protestingly dragged into near-death situations by rogue cop Pitt.
