"Cas, what the hell are we doing here?" Dean asked a little disoriented from being suddenly and unexpectedly zapped cross-country by an angel. A moment ago, he had been standing in a dim motel room and now he was squinting in the sunlight, in the middle of a very familiar scrapyard. Cas didn't reply, he just dragged him by the hand towards Bobby's front door. "We're supposed to be working a case," Dean protested. Just before they reached the porch, Cas turned around to him and looked at him intently, his blue eyes even bluer in the sun.
"There are so many unconventional things about you, Dean. Your childhood, your lifestyle... us." Dean smiled a little at the sound of that last word. It all still felt very new to him. Very new, and very good. "You deserve some normality," Cas continued. "I've been doing some research and I believe this is the correct social convention."
"What is?" Dean asked, both amused and slightly frustrated by Cas's secrecy. Cas knocked firmly on the scuffed door and waited for the sound of Bobby's footsteps to come along the corridor. When the door opened, Bobby raised an eyebrow and stared at them like they were both insane.
"What the hell are you knocking for? You know the door's open."
"Mr Singer," Cas said, extending his hand. Bobby squinted at him from under his tattered cap. "I know we've met many times before, but I would like to formally introduce myself. I am Castiel, angel of the Lord, and I'm Dean's boyfriend." Dean's face fell. He stared at Bobby with wide eyes, feeling heat rise up his neck and creep on to his face. Bobby just blinked.
"His… boyfriend?"
"Yes," Cas said, with an affirming nod.
"Boyfriend?"
"Yes," Cas repeated. Several agonising seconds passed where Dean dearly wished the ground would swallow him whole. He waited, terrified for Bobby's reaction. At long last Bobby just shook his head and grinned, pulling Cas in to a tight hug.
"It's about damn time," was all he said, releasing Cas and stepping out on to the porch to stand in front of Dean.
"What are you looking so skittish for?" he asked. Dean had been so blindsided by the entire situation that he found he couldn't form a coherent sentence. "Lighten up, ya idjit," Bobby said, embracing Dean and clapping him heartily on the back. "I've never been prouder."
