I did not care for that "revelation" from Ben in Fraction's Fantastic Four. I just feel like they are muddying the waters up too much with the events around Doom's college experiment. I was fine with the one where it showed that he was successful in contacting the netherworld but the demon he encountered clawed up his face for his transgression. I think it was first hinted at in PAD's Reed Richards: Before the Fore and then Brubaker expanded on it in Books of Doom. Props to him for tieing in the PAD story.
