I just finished the latest episode, I didn't expect that fate for Mike. Jesse is sure to find out, and when he does I don't expect anything good to come out of it. Mike was a mentor to him.
am disappointed there only making 1 more season
I think it's good to end it while people still like it. Having another few seasons probably wouldn't make sense. Series like these don't come around too often, you want to remember it as an entirely good show, instead of "that one show that started out good then got bad because they dragged it on".
