AN: So, here's that epilogue I promised...

Epilogue

It was now two months after Cas had rescued Sam and Dean, and all injuries were healed on the three men, although, per Cas's request, Sam knew nothing of Cas's self-inflicted wounds. Two days after Sam's birthday, Dean sent Cas to the store, using the excuse that they were out of hamburger meat and Dean wanted hamburgers for supper. When Cas asked why Dean couldn't do it, Dean said he had stuff to do. Cas looked at him skeptically, but apparently decided it wasn't worth the effort and just left. As soon as Cas had been gone for an amount of time Dean deemed safe, he hunted his brother down. He found him in his room doing something on his laptop.

"You know, you could knock," Sam said when Dean just opened his door.

"I didn't know if you were actually in here or not," Dean said defensively.

"So what, you just wanted to go through my stuff or something?" Sam asked suspiciously.

"No. I wanted to talk to you, as a matter of fact," Dean said, still sounding defensive.

"Really?" Sam said dubiously. It was a rare day when Dean Winchester went looking to talk to someone. Talking sometimes came dangerously close to chick-flick moments.

"Yeah. I wanted to ask you a question. Your answer may not change anything, but I still thought it might be a good idea to ask."

"Ok, shoot," Sam said, putting his laptop down beside him to show Dean that he had his undivided attention.

"I… Great, now I don't know how to word this," Dean muttered, not looking at Sam. Finally, after a minute, he said, "What would you say about me getting married?"

When Sam didn't say anything for a few seconds, Dean looked up to gauge his reaction. Sam was looking at him… unreadably, which was not ok with Dean. Then he asked, "To whom?"

"Well, Cas, who else?" Dean said, annoyed. What was Sammy thinking?

"Are you asking my permission to propose to your boyfriend?" Sam asked in a tone Dean didn't really appreciate.

"No," he said quickly, although now that he thought about it…

"Well, I guess that's fine with me. You got a ring or something?"

"I wasn't planning on either of us wearing engagement rings. I was just gonna ask him sometime, and then I figure we can pick out wedding bands together. Unless he wants engagement rings we aren't going to do them."

"I get it. Well, let me know once he says yes," Sam said almost casually. If you asked Dean, Sam wasn't taking this thing seriously enough. Then suddenly there was a look on Sam's face that let Dean know he was about to say something that was serious. "Listen, though, if you do anything to hurt him, I care about him too, in a different way than you do, but he's still the closest unrelated friend I have now, so if you hurt him I reserve the right to make you regret it."

"You got it," Dean said. He hadn't expected that from his brother, but now that he'd gotten it, it didn't surprise him.

A few days later, Dean was laying beside Cas in their king-sized bed when he decided it was time to pop the question. After giving Cas a soft, chaste kiss on the lips, Dean looked in his eyes, making sure the other man was listening, before he said, "Cas, you know I love you, more than anything, right?" When Cas gave him a nod in answer, Dean continued. "Well, I was thinking, and I know the both of us know that we plan to spend our lives together, and that there's no one else but each other, but, well, would you like to, um, marry me?"

Cas looked at Dean, trying to make sure his mind wasn't playing tricks with him. As soon as he was sure, he said, "Yes, Dean, I can't think of anything else I'd rather do."

The next morning Dean and Cas woke up at the same time. After sharing a short, sweet kiss, they got out of bed, got dressed, and went to the kitchen to find Sam already working on breakfast. He looked at Dean with his eyebrows raised. He'd been giving Dean that look almost every time he saw Dean for the first time after some time lapse, ever since Dean had told Sam of his plan to ask Cas about marriage. Dean wasn't sure whether Sam was trying to make sure Dean didn't forget or he was just trying to figure out if the question had been asked. It was annoying regardless. This time though, Dean just smiled and nodded. If possible, Sam's eyebrows went even higher, although Dean could hardly tell since they disappeared behind his brother's ridiculous hair. He seemed to be asking what Cas had said. "He said yes," Dean told him.

"Congratulations," Sam told them both.

"Thank you," Cas said.

"I'll be right back," Dean said after breakfast was finished. "I gotta take a leak."

As soon as Dean's footsteps had faded, Sam looked closely at Cas. "Listen, I know you love Dean, but you need to understand something. Dean's the best brother I could ever ask for, so if you ever do anything to hurt him, I will make you regret it. Is that understood?"

"Of course, although I do hope you realize I really wouldn't hurt your brother," Cas said, looking puzzled.

"I'm glad to hear it," Sam said, just as Dean returned to the room.

Sam would never know how, but somehow Dean figured out what had happened in his very brief absence. "You didn't," he said to Sam.

"Didn't what?" Sam asked, feigning ignorance.

"Give him the 'hurt him and I'll kill you' talk," Dean said.

"Maybe," Sam said.

Dean rolled his eyes. "Gigantic freak," he muttered at Sam. All that earned him was a hard nudge on the shoulder as Sam moved past him to refill his coffee.

The End

AN: Hope everyone enjoyed! As always, leave a review. I have an idea for a new story, but it's questionable whether it's going to come to anything. Don't expect anything for a while because I'm probably not going to start posting a story until I've written all of it If you have a prompt, PM me and I'll see what I can do.
