Look back AT the frames from the SEASON finale I believe I have hit upon SOMETHIGN!! Looking at the electronic photo BELOW I have found a strange GREEN glow!! It is is IDENTICAL to the glow that TIGHT wearing SUPERMAN Clark Tent feared so much!! I think that DESMOND was smuggling cryptonite and THAT is what is behind the WALL and what caused the MAGNETIC anomoly that Desmonds girlfriend Polly WAS tracking in the Igloo!! I have measured THE green hue/tint and THEY are identical!!
