Castiel was frustrated. Extremely so. His attempts to speak with the Powers That Be had failed, repeatedly, and he sensed that things were only getting worse. More people were being changed and Sam without his girlfriend was not a pleasant thing to witness.
Every now and then he tentatively reached out to Ruby's apartment, trying to see if his girlfriend was even there, but as ever the hex bags she wore kept him from even sensing her. So the shock he felt when there was a definite presence in her apartment staggered him. In an instant he appeared there, looking at the screaming girl sitting on the floor.
It took him a moment before he realized. He knew that soul. He was used to it twisted, darkened by Hell. Here it was pure, in it's original mortal state.
Ruby. As she'd once been.
Castiel stared dumbfounded at her a moment before he sat down heavily on the chair just behind him.
