As the novel progresses, the darkness spreads not only on the island, but is referred to throughout the characters. The darkness really starts to get noticed when Jack breaks away from Ralph and Jack has "his side of the island." Jack's side of the island is dark. However, as the Id triumphs over the Ego and Superego (Jack gains power over Ralph and Piggy), the whole island becomes dark. Actually the island on fire (not just regular fire, that represents a whole new importance) is also a representative of an indirect dark because the island is now a "personal hell" i.e. the fire engulfing the island.

The darker shadow is the darkness side of Roger's personality. Roger was struggled between the civilization rules and the wildness inside the moment before. When he opened his eyes, his dark side of personality overthrew the ruining social rules, thus he felt a darker shadow crept beneath his own skin. Since the whole process was taken placed in Roger's heart, of course Jack can't notice that. In another word, this shadow is the Lord of the Flies which represented the darkness of human hearts.
