Castiel sneered at the yellow eyed bastard, tugging Ruby to his side. There was a brief pause before he let the wings stretch out, a wind whistling past them all.
"We'll be leaving now."
A part of him wanted to try to send the bastard back to hell then and there, but he knew that Azazel was different from most demons and there was a faint chance he alone would fail against him. And right now he didn't want to take the chance.
So he focused his power, the wings closing around himself and Ruby as he travelled them both to a new location far, far away from Azazel.
