"Anything," Bela repeated, her self-satisfied tone very apparent. "Anything in this God-awful city, and there certainly is a lot of it to kill, isn't there?"
She held Lilah's gaze for a moment as she thought of how best to describe the entities that were Azazel and Lilith.
"Azazel is the first. He enjoys making deals with people... they both do, but he makes a habit of it. Lilith tends to simply hold the contracts. Azazel attempted to create an army for himself by feeding babies his blood at birth. The children developed powers as they matured... one of them is here now, actually. He's rather adament about how much he hates Azazel, but he could still be a problem."
Never let it be said that Bela would pass over the chance to screw the Winchesters.
"Lilith..." she paused again, pursing her lips. "She's incredibly powerful. Often possesses the body of a child in order to be underestimated. She likes playing with families. She holds contracts... she held mine at one point, though I intend to see that doesn't happen again. There's no way I've ever seen to beat her, other than the gun."
