The days since Gabriel had become a demon were full of sorrow. The hours dragged on and he could feel his tough resolve slipping away. He longed to have his grace and wings and the power to be the God of Mischief once more. His existence was spent making sure the apocalypse was still on schedule. He was forced to complete his brothers' 'Apocalyptic Checks and Balances'. Gabriel made sure Death was still on his leash, that the angels were still no closer to putting Lucifer back in his cage. All from the deep dark depths of Hell.
Every day Crowley would come to him and offer him a more 'grounded' job. He was asked every day to hunt the Winchesters. Without fail, Gabriel would look Crowley in the eyes and deny. Gabriel, though now a despicable creation of his brother, still kept the same morals he had as an Angel. Though not always the correct ones, still they were morals. The longer he spent down there the more, though, he could feel his body weaken. He needed sunlight, his body craved it.
Gabriel had finished that day making sure that nothing stood in the way of the rising apocalypse when Crowley came to him. "You already know my answer. I don't see why you continue to ask me," Gabriel said his annoyance painted on his face. "Oh it's not an offer today, Gabe, it's an order," Crowley smirked at Gabriel's stunned expression, "The order was just sent out and since you were the last to see the two, you're our man for the job." Gabriel felt his heart leap. He was going to get out. He was going to leave the darkness. He could not help keeping a smile off of his face.
"See. I knew you had it in you. Hell has really changed you hasn't it? I bet if I WOULD have asked you, you would've said yes. The darkness gets too much for them, see? They need the earth and the dirt under their toes." Crowley said circling Gabriel. "And to think you used to be and angel of the Lord."
Gabriel's blissful fantasies were destroyed when he realized what he was being sent to do. He was going to have to kill Sam and Dean.
