It was Reyes for me, at a base level, Sloane was a drug lord and B grade crime boss. At a deeper strategic level, if I am to play MEA2(if its ever gonna be made), Reyes seem like the one who would progress the story further, taking it deeper and darker. What I didnt appreciate is how ryder played out in the scheme, I would have preferred to storm Sloane's HQ in a gunfight rather than watch her get shot in the back and did nothing. Then again perhaps Bioware needed this to play out so that Reyes have a little hold on Ryder. Will see how it plays out, well worst case scenario, I will replay MEA again and progress the story the way I want it to.
