His wand was broken. His bloody wand was broken. He was helpless and they were stuck here. He didn't even know how that had happened. Maybe he had steadied himself in the wrong way. Sirius snapped out of his stupor as Heather asked the stranger. The man smirked. "Oh, I can fix it," the guy said. Sirius' look of despair was replaced by pure glee. The man's next word erased that feeling from his body again. "But I won't."
Sirius stared at him. Disbelief turned into anger. "I can bring us out of here. I want to bloody help the two of you, you jerk. Who do you think you are?" Sirius bellowed.
"Wrong question," the other man stated calmly. Sirius wanted to wipe that annoying smile off his face. "The right question would be: What do I think I am? Correct answer: A demon."
Sirius blinked. And then blinked again. Had he just really said 'demon'? Alright, Satan himself was here but so far he hadn't met him. His head snapped into Heather's direction. "You drink beer with a demon?"
(Ooc: The diamond or the necklace could work. The not removing them doesn't actually keep Crowley from doing something to them. How about the necklace turned into one of these necklaces made out of sweets that you can buy on a fair?)
