Envy's ability just multiplies another Sin's ability, in proximity. That's why he has so many sex scenes. But that's the only one I'm gonna definitively say, ;P
That's so interesting! Sorry. I'm a huge nerd when it comes to lore of myths, religions, folklore, and fairytales. So of course I started quietly obsessing over the abilities of the sins. xD
But ugh, you hiding secrets. No fair, you evil person. =P
