"I do not understand why humans do this."
"Just... humor me, Cas. Please."
"As you wish," Cas nodded, the breeze fluttering his trenchcoat as he walks along side Dean. The little cemetary is nothing of interest to him, but he knows it's important to the man he's come to love and will do anything he asks. He nearly smiles as Dean takes his hand and they slow down their pace. "Where is it?"
"Right here," he leads them over towards a medium size, peach colored granite headstone. The name Mary Winchester engraved in a plain print with her date of birth and death below it in a smaller size. Next to this, embedded in the ground, is a square piece of metal that says John Winchester and nothing else. Dean releases Cas' hand and kneels down in front of his parents' graves. He reaches out, placing a rough hand against the smooth stone and gives a crooked smile. "Hey, Mom. I know I've only been here once, and that was during a hunt. I just... it's hard. I guess I'm like Dad. Rather push everything down and bury myself in work than think about things like this."
He pauses, the sun beaming down on himself and Cas with a warmth he nearly felt in the depths of his battered, tainted soul. Closing his eyes for a moment, he can still see his mother clearly. Her blonde hair, her dark eyes... her smile. Making his mother smile was something he did a lot growing up. It always made him happy.
"I miss you. Every day. Anytime I have a piece of pie, I think of all the times we made pie together when I was a kid. Especially cherry. I wish Sammy had the same memories I did. He missed out, and I don't talk about it much, so... he doesn't have a lot to go on. I'll try harder to give him some good things to remember. I love you," Dean turns to the marker for his father and takes a deep breath. "Dad. I'm going to be honest. You really screwed us up. It's easier to understand now, but... sonofabitch, Dad. We sacrificed so much, and got nearly jack shit in return. You went to hell for me, I went to hell for Sammy, he went to hell to save the world from the Apocalypse. You put so much on my shoulders and I can't believe I didn't snap. I'm not trying to be disrespectful, sir, but... I had that on my chest for years. I love you, too. Even though we never said it to each other's faces after Mom was killed."
"Dean? Are you alright?" Cas spoke up after Dean went silent for several minutes, still kneeling on the ground. Sniffles were all he got until Dean finally looked up at him, his bright green eyes shimmering with tears. His hand brushes them away, feather light.
"I'm fine," he replies, turning towards the graves. "Guys, this is Castiel. He's an angel. I guess you were right about them watching over me, Mom. He's the one who saved me from hell and now... we're together. I know, Dad, after all the girls I've been with. But this is different. Cas knows everything about me... he'd die for me, and I'd die for him. I love him."
"You didn't have to say that."
"Yes, I did. Because then they will know why I'm doing this," turning his body around, Dean situates himself so he's kneeling on one knee and affectionately holds onto the hem of Cas' trenchcoat. "Castiel, you've been there for me and done things for me when everyone else turned their back. Will you marry me?"
"Dean, you are not playing a practical joke on me?"
"Does this look like it's a joke?" Dean pulls out a small black velvet box, revealing a solid ring made of silver and iron. He takes Cas' hand into his own. "So... will you?"
"Yes. I will," Cas replies without hesitation as the ring is slipped onto his left ring finger. He pulls Dean up to his feet easily and brings their lips together for a deep but meaningful kiss. The sun continued to shine on the happy couple and on the grave sites, as if something was smiling down upon them that sad turned happy day. "I love you, Dean."
"I love you, too, Cas."
