The stars are screaming, Cas signs one warm night. He’s lying with Dean on one of the hills nearby their houses.
He has never been able to hear anything other than his own thoughts, but now, when he’s staring up at the stars, he swears he can feel their pain, the vibrations of it running through his body.
He has never been able to hear, but he’s certain that crying must sound just like this.
The stars are screaming, Castiel repeats after pointing at the night sky. They’re screaming like the universe is going to end.
Dean stares at him, surprised, and then signs, You can hear them?
The boy shrugs his shoulder. I think so.
They stop communicating soon after, too absorbed in the starry sky. Even though Cas isn’t looking at Dean, he knows the other boy is trying his hardest to hear the stars, too.
Dean’s mother dies a week later, and when Dean tries to stop his fingers from shaking to sign his friend what happened, Castiel knows immediately.
The stars were right to be crying so loud, he wants to say to Dean with his untrained, soundless voice. Dean’s eyes are too full of tears to see Cas talking, after all.
The stars screamed of worlds ceasing to exist and one of them has truly come to an end.
