Well at least Mike waited 5 apples time for the man to throw the trash out to see the cash, and then used his black light to trace the money to the sink.Why the exchange? I don't know. But Mike isn't really a 'bad' guy per se. And Mike and Jimmy both got their own code.Its interesting to see the characters develope their code. And I am way more interested to see how Jimmy break down to becoming Saul.
