It was written as a tumblr prompt for Lorielei. She had to choose 3 words. The words were: baby, fallen and wings.
I will be your water in the desert
Dean wakes up when he feels something burning hot dropping on his bare shoulder. Before he turns the lamp on, he hears a muffled sob and sniffling.
"Cas?" the hunter whispers drowsily.
When he turns the lamp on, Dean sees that Castiel is still asleep but tears are streaming down his face.
"Hey, are you alright?" Dean's voice sounds so soothing, comforting and it wakes the fallen angel.
"Dean?" Castiel sounds so lost, confused. He looks around, not understanding what's happening. Then he feels wetness on his face and wipes the stray tears off that are still rolling down his cheeks.
"You had a nightmare, did you not?" Dean slowly wraps his arm around Castiel's shoulder, pulling him closer until the ex-angel puts his head on the human's chest.
Castiel lets out a shuddering breath. "Yes," he whispers. "My wings….They…they were burning while I was falling from the sky."
Dean swallows hard and tries not to show how much it hurts him too. He needs to be strong. For Castiel.
"You are with me. You are safe in my arms, Cas. You will always have me." He says quietly and kisses Castiel's forehead.
"I know, Dean," the ex-angel murmurs and snuggles closer to the human. To his human.
