Afton is probbaly rotting in hell (like litteraly, he probbaly IS, depending on what you belive, he is still dead.)
Also the scraptrap suit's probbaly gone/burnt like kfc
Of course if you wanna use speculation, perhaps afton gets burnt/explodes, and then just gets dragged to hell (or tormented by the TOYSHNK)
Though im probbaly gonna stop talking about this since, i gtg to bed soon lol (nice chat ig)
