Old Joe: (after Young Joe threatens him) Why don't you stick your little gun out in between your legs and do it... boy?
*Young Joe reaches for his gun, only for Old Joe to deliver a Groin Attack and knock him out with one punch*
After Old Joe kills every single member of the mob, he shows up giving Young Joe all of their profits telling him that he can go on with his life. This causes Young Joe to explode with rage, calling Old Joe out on his hypocrisy and delivering a massive "The Reason You Suck" Speech while unloading his weapon in his direction, almost landing a few shots in the process.
A Dying Moment of Awesome, but the ending, where Young Joe realizes that, as things are, Cid will become the Rainmaker no matter what due to the actions of Old Joe, and realizes that the outcome would happen again and again. So he changed it...
It's negated slightly by his bungled escape down the fire escape, but Young Joe escaping his occupied apartment is awesome. He gets the jump on Kid Blue and knocks him into the silver safe, crushing Blue's shooting hand. He then escapes Blue's backups.
The diner conversation, from a cinematic and acting perspective. What Old Joe does at the end is another CMOA.
