Summary: Dean can’t say the words. But Cas knows. He knows exactly how to break Dean’s walls down; too much but just enough.
Based on this prompt from tumblr: Imagine person A lightly tracing “I love you” over and over again on person B’s back, assuming that person B is asleep. When person A is lying on their back, getting ready to sleep, person B moves closer and wraps their arms around person A, whispering softly, “I love you too.” Bonus if that’s the first time person A has ever declared their love for person B. —@otpprompts
Also based on the pictures of Jensen and Misha watching the sunset, and the episode "Angel Heart."

"Many things have happened, but that emptiness that haunts him wherever he goes, so ironically filling his soul, remained right there and Dean never spoke about it, didn't let anyone understand and feel it too.
He knew that there would never be such a person to whom he could entrust it, who could save him from it, completely free him. He knew there would never be anybody who would need him the way he is. Dean was completely sure of it.
At least up until recently. "
OR
AU where after the end of 11th season Dean gets sick after the hunt. He is stuck with Cas in the bunker, who takes care of him, while his powers are slowly fading away.
