I beat the game but chose the ENDING where you KILL Trevor, because I assumed C would have them both die, but then I replayed C to see what happens and it was a 40 minute long mission that was fantastic, I reloaded a save that was like 11 missions back just to redo everything and do the C ending so I still had Trevor to play as.
It's cool how the 6 heists all have 2 different ways of doing them, it's like 12 heists kinda.
I saved almost all of the strangers missions for when I finish the game, so now I'll be doing those.
I have 6 days before online comes out to get 100% solo or else I never will.
if you get mad at me for spoilers forget you I capitalized ending and kill.
