Remember all those episodes where we slowly found out that everyone hired was a free mason, all their companies owned by free masons???
What if the masons are just burning the Lagina brothers fortune just for humour? Just to delay finding out whats really down there?
Think about it, the free masons and templars have knows whats down there and have helped built it why cant they go to the records and find out whats down there or where the treasure is hidden?
Because theyre just funding something bigger with the Lagina brothers money!
