The worst nightmare Castiel has after he falls is of Purgatory. He wakes up to Dean hovering over him, hands pressing his shoulders down onto the bed and green eyes full of worry. Cas knows that he’s been crying, he can feel the tear tracks on his cheeks, but the nightmare is so fresh in his mind that he can’t speak, can’t tell Dean what happened.
“Cas, I’m going to let go of your shoulders now, ok?” The ex-angel nods and feels Dean pull back, but the breach of contact doesn’t last as Cas flings himself in the author’s arms, tears falling again.
“I’m sorry. I’m sorry. I’m sorry.” He’s choked up, the words coming out of his mouth all mangled, but Dean gets what he’s saying as he runs one hand through the former angel’s messy hair, while pressing kisses to his forehead, trying to get him to calm down.
“It’s ok Cas, it’s ok. You fixed it, alright, it didn’t happen. You made sure it didn’t. But it’s ok, I’m here. I’ve got you.” They stay like that for the rest of the night, Dean sitting with his back against the headboard and Castiel curled up in his arms. And in the morning, Cas will insist that they don’t talk about it, so Dean will just shove a plate of pancakes at him with “I <3 U” spelled out in chocolate chips.
Cause Dean knows in the end, it’s the little things that count the most.
