He set his foot on the mortals back, letting flames spread along side of himself. "Find out Mikey. Or I'll come back and find every little thing your pet enjoys and turn it to cinders. You have a month." He raised his hand and created a path of flames in front of his brother.
"I'd say you have about thirty minutes." He looked down to the mortal, reaching down to make him look at Lucifer. "I see more then you think. I will make you watch everything you love turn to ashes before I let you die a slow and agonizing death. Make sure my brother remembers that."
He released the mortal and went out through the window.
