I stopped watching after season 1. The idea that a pirate buried treasure there is ridiculous. A pirate crew was generally made up of equal partners who split any plunder an then spent it at the nearest port.There definitely was a very elaborate pit built there but the idea that a treasure which would never be retrieved would be buried is inconceivable. Too isolated and complicated from an engineering point of view to be someone playing a joke. Rather than waste any more time thinking about it, best just to drink another beer.
The grim reaper only gathers the souls of the dead, he does not kill. If you believe in that sort of thing. According to the plan, every life, every event, and every death is predestined and unavoidable.
Looks like Phil is history. Maybe?
