When Cas gets this contemplative look on his face at the tattoo parlor where they get him his anti-possession tattoo Dean doesn’t make much of it. He just tells Cas to hurry up when he pauses to whisper something to the tatoo artist, gesturing as the other man nods back. He starts to notice when Cas withdraws into their room for hours at a time in the next few days with a sketchbook and pencil in hand. When asked, Cas just gives him a small smile and says he’ll see soon enough.
A few more days pass before Cas finds him in living room and gently places the sketchbook on the table before him. It’s flipped open and Dean’s vision is filled with wings. Sketches upon sketch of wings, some rough some detailed, and near the bottom, on drawings of backs.
“They’re beautiful, Cas.” Dean murmurs, a little confused and looks up to see Cas beaming at him, eyes shining with an excitement he hasn’t seen in Cas since he became human. Maybe even longer.
“I want them. I talked to the man who tattooed the anti-possession sigil on my chest and he said he could do wings too. I-I mostly drew them from memory, from how I remember them manifested before… and I took some qualities from my true wings and added those too. Will you take me?”
Dean pauses for a second, not in hesitation but because he can’t stop staring at the change in Cas’s face, how excited he seems. And the decision is nothing, simple really. “Of course, Cas. If that’s what you want.” Dean smiles back at him, reaching over to give his hand a quick squeeze.
Cas nods, that light still in his eyes. “I do. They can’t compare to my d wings of course but I want to honor them, and to keep them in my memory I suppose. This seemed like an apt way.”
They go in the next day, hand in hand because Dean notices somewhere along the way how much Cas’s hands are shaking and that the excitement has been replaced with a jittery nervousness that he can almost feel rolling off Cas. “Hey, don’t worry, babe. You’ll be fine, hm?” Dean whispers when he feels Cas clutch his hand tighter as they walk in.
He keeps a hold on Cas’s hand through it, whispering little encouragements to him.
And after, when they’re shown into a room with wall to wall mirrors so Cas can see the result and he breaks down crying at first sight, he holds Cas against him and tells him how beautiful they are, how beautiful he is. Cas just buries his face against Dean’s chest and sobs but Dean thinks they’ll be alright because this is so different than all the other times he’s held a crying Cas in his arms this past year. Because when he pulls Cas’s face up to press a gentle kiss against his lips, he can feel the curve of his smile.
