It is just a speculation, but the sum of the atomic number of Fe(26)+Li(3)+Na(11) is 40 which is the Zr (zirconium) atomic number. Which is described in Wikipedia as: “The name of zirconium comes from the Persian word “zargun”, meaning “gold colored”. It is a lustrous, grey-white, strong transition metal that resembles titanium.” We could make a lot of connections. Like the Elliot’s enterprise name (Gray Matter) and of course White. The gold colored that could stand for Walt’s money, and even for the titanium for what Walt’s have become, I mean, almost indestructible, but I doubt it all to be meant, I think it is just a big coincidence. Just a though.
