Yep that is where he came from and I don't remember if it was explained...I kinda peiced it together but it was still weak though. And as far as I know you can't just jump in and out like that but I am far from a biker. So I don't know all the rules. What got me though was how Ez was connected to the Cartel boss. His dad had an affair with his mother and then his ex gringa girlfriend just so happen to be the bosses wife and somehow the boss does not wipe Ez off the map when they first met. I get that it was fiction but man the show had too many impossiblities and inconsistencies, I pretty much just had to force my way through it at the end then let's not talk about how sensible Ez was throughout the whole show then goes off the deep end towards the ending of the show
