Deliberate mistake: "Treasure of the Ages": Darien delivers Mary's child during the hurricane. There's no time lapse in the scene, but somehow the kid emerges perfectly clean: no blood, no placenta - and no umbilical cord. Darien also neglects to wash his hands before reaching in to turn the breeched baby around. (Ewwwwww!) (00:45:00)
Plot hole: "Cool Hand Darien": In the swamp, Luther overpowers both guards and escapes. As they were both out cold and no one else was around, he could easily have taken the keys from them and unlocked his leg shackles. Instead, assumedly because it's more dramatic, he sneaks back into the prison compound to steal a sledgehammer and break the chain. (00:34:30)
