Davy Jones

Cherub told a dying Joseph Longfoot that it would be unlike him to go to Davy Jones's silent after he cursed him. (TV: The Smugglers)

Davy Jones was mentioned as part of The Ballad of Captain Avery. (PROSE: Susan's Diary, Stop, Thief!)

Behind The Scenes
In real life Davy Jones's Locker is a metaphor for the bottom of the sea: the state of death among drowned sailors and shipwrecks.
