He'd always said it himself... Don't take shit from other demons. He knew better than to make Deals with others, risk his soul, but then again, he always had that authority to snap those chains like they were made of candy.

But this was... different. Rather than simply shake hands and have an accord, when those long fingers opened to reveal a pair of rings, he was reminded of when he finally let go of that gold band he hung on to.

Momentarily, the Devil had to blink. Was... was Alastor...?

But his eyes narrowed, blazed as he reached into that hand and took one of them. The time for questions was later. Hesitating only looked worse.

He took that left hand of his, however, and the grin widened. His power lifted, like any other Deal, and it coiled like a serpent. "Hahah... You surprise me every day, Alastor. ...Deal."

He'd done this just once before, of course. But he wouldn't forget how to slide a ring upon the last finger of the other's hand, at a pace that was without hesitation, but nothing so quick as to get it over with. Once it was on, he traced a thumb over the back of that hand. He let that coiling power curl, brush like so many of his own pearly scales, invite his partner's to join in.
