I guess this counts as GTA IV spoilers too so be warned. I'm not using spoiler tags for easier discussion.
We all know in Blood Brothers there's a choice to kill Derrick or Francis, but that's not the real point here. In GTA V Packie is a character you meet through a random event and can use him for heists.
I used him in the Paleto Bay bank job and something interesting caught my attention. On the way to the job they all talk about their first jobs and of course Packie talks about Three Leaf Clover in detail, but then he starts to mention Derrick and says something a long the lines of "god rest his soul".
So it was the canon choice all along? Has anyone noticed this?
