So - it's 1946, and Michael is just getting out of the USMC - what are we supposed to believe he is doing for a living or where is he living period? - the wedding is in the summer - the assassination attempt in December?
Maybe he still has a taste for killing people that's nagging him - and what is he going to do? - he's like what? 26-28 years old at the most - and doing what in 1947 - brooding and hoping for some other opportunity to show up his father and Sonny?
