So I was listening to the beginning chapters to gather intel for my next blog update and in Chapter 3 part 2 when Saul and Angel pick up Burt, he makes mention of being raided and it sounds like he knew who it was. They were professional very professional in order to get into his safe. Could this be a link with Burt and the mallers? or Scratch? Not saying he's the rat but I think that is a link.
