Desmond didn't see any reason he shouldn't tell Susanoo. "I can control and manipulate dark energy, think of it as the negative aspects of the world, or rather what makes those aspects so negative in the first place." He splays his hands and starts moving them, rapidly and in complicated patterns. Soon he makes a miniature galaxy, complete with small stars and blackness flowing around in eerie patterns.
"The stuff I control would be the blackness, the unseen dark energy that hides among us. Any act of bad will, be it simply lying or something as bad as murder will create new dark energy. That's why it gets easier to lie every time, and why serial killers are able to just kill on a whim, as if they didn't care. The dark energy a being holds has a big influence on what that being's personality will be. The purest of hearts have almost no dark energy, while the most disgusting rat of a man is filled to the brim with the stuff."
He clamped his hands over his creation, reabsorbing it, and he smiles. "Pretty cool, eh? What about you, what can you do there, sexy?" He smirks at the other male, leaning against the wall. He noted this in his subconscious. He didn't normally act this cool, did he? And he would never say... that! Not to someone he barely knew!
