So I've been playing a lot of Gears of War 2 lately and thinking about the games plot.  There are a lot of unanswered questions out there and have me wondering what is in store for Marcus and Dom in the next two games.  Yep, I believe in the four Carmine theory which I'll explain later.  I've been thinking about where do the Locust come from, is Adam Fenix alive, is he along the Locust,  why introduce "rust lung", why are the Locust taking prisoners  and  why the Locust queen goes on about unintended legacies at the end of the second game.  I have a few theories and plan on posting my theories here to see what people think.  I will of course have spoilers for the game's story but if you haven't played through yet what are the odds you ever will?
