Naw i didn't really feel the reveal either. Most people knew he was coming back, but the way the just tossed him into the end of this episode didnt feel right. Its like "hey, all hell broke loose in the prison and now they handled it....but wait, looks whos here. Its the GOVERNOR." Also your right about his appearance too. This is a few months after last season right? It seems like he took a long walk to clear his head and came back to continue where he left off. Dude should have been driven batshyt crazy thinking about revenge. Maybe he is, but to me it doesn't seem like it. If he turns out to be anything like this
Then this is gonna be a wild season
