Based upon a really cute gif of Dean on Tumblr.
"So Dean…"
Dean looked up to find Charlie standing next to him. He smiled softly. He had missed her more than he would ever admit. "Hey Charlie."
"I've spoken to Sam about…something that caught my interest." Her red hair danced around her face as she said down, and Dean got a strange sensation of fear. What had Sam told her?
"Yeah?"
"Oh yeah. We were talking about me and Dorothy and then suddenly he blabbed out…" She took a deep breath. "An Angel? Seriously?"
Dean stared at her for two seconds, then looked down with a smile, chuckling softly. "That's what you say? Not 'Jeez Dean, a guy, huh?' or 'I didn't realize you were gay.'. No, you find the major problem that he's an Angel!"
"Hey, I always knew you were at least bi! You're…I don't know. I think we gay people just sense it. But seriously? An Angel?"
Dean chuckled. "Yes, an Angel. It's not as if I can help it." He looked up, seeing Cas standing a few feet away, with his new trenchcoat, examining a sun flower closely.
"You guys are a bunch of crazy people!" Charlie exclaimed, smiling brightly. "Of all the gays out there, you go for an Angel." She shook her head at him, but the mood was light. "Dean Winchester, if you can do it weird, you will, huh?"
"Of course!" he said, his stomach jolting when Cas turned around and smiled softly at him. He smiled back, his heart beating faster immediately. "That's me." he added, softer, his mind already gone to later that night and his bedroom.
Sorry if it sucks, it just came to me
