Chapter Two

The ceremony was over, and everyone was milling around, families gathering for hugs and congratulations. Sam pushed through the crowd, catching a glimpse of Jess as she stood with her parents. Their eyes met, and he sent her a smile filled with love before continuing to search for his parents before they found each other.

"Sammy!" A strong arm wrapped around him, and he looked down, smiling.

"Hey, Dad. Wedding suit? Really?"

Dean grinned, although there was still the permanent touch of sadness in his eyes.

"Yeah, well, never needed another. Why bother? It's not like I'll ever date again"

Sam ignored the pang in his heart as he thought of Dean, alone in their old house, refusing to move on and simply moving between the only three rooms he ever used – kitchen, bathroom, and the bedroom he used to share with Cas – like a ghost. He gave his father a one-armed hug, having to bend down slightly, before straightening up.

"So…have you seen him yet?"

A shadow passed over Dean's face.

"No, and I was hoping you wouldn't mind if I left for the hotel a bit early so I can avoid that pompous – "

"Hello, Dean"

Dean's heart stopped and his stomach dropped, blood rushing in a decidedly downwards direction at the sound of that voice.

How could it still have that much power over him after five years of ignoring, and being ignored in return?

Clenching his jaw determinedly, he turned around and faced his ex-husband.

"Castiel," he said curtly, before attempting to head in the opposite direction.

Sam grabbed his arm.

"Dad, wait. Can't we just be polite? Please? Just for today," he begged, remembering the shouting match the two had had down the phone just before Castiel had moved to Colorado.

Dean gritted his teeth even more before grounding out a reluctant "fine", which contrasted heavily with Castiel's "Yes, Sam".

"Sam, I can't begin to tell you how proud I am of you. You have achieved so much, and I hope you enjoy your trip to Europe. I only regret that we were unable to communicate with one another more. However, know that no matter what you do, your father and I will remain incredibly gratified that the boy we raised – "

"Don't you fucking dare think you can speak for me, you ignorant ass," Dean burst out, unable to think straight anymore. How dare he, how fucking dare he, waltz in here like nothing had happened, like he was still there for Dean and Sam, when he'd just left at the drop of a hat?

He said as much, glaring at his ex-husband, tears that he hadn't shed since the night Bobby had taken him to hospital and he'd had to tell his father that someone else had left him threatening to spill.

"You arrogant son of a bitch. You think you can just come back here and act like nothing happened, like you still have a claim on Sam, on me? You left after promising me you would never leave, and you didn't look back. So don't you dare, don't you dare, think you can talk to my son like that, because you threw away the right to do that when you threw me away."

Sam was frozen, looking between Dean, who was clenching his fists in an effort not to cry there and then, and Castiel, who was stuck in place, looking at Dean like he was terrified.

"Dad – Cas – can we, uhh…everyone's looking at us. Crap. Can we go somewhere more private?"

"I think that would be best," Castiel finally managed to say evenly, not taking his eyes off Dean

Dean could only dig his nails further into his palms, struggling between punching Castiel in his stupid, gorgeous face, and collapsing on the spot.

One of the rooms in the graphic design building was unlocked, and the trio found themselves in there. Sam observed as his dad and stepfather stared at opposite walls, resolutely ignoring one another.

"Look, you-" He began, but Dean cut him off.

"Seriously, why am I still even here?"

"I would assume that it was because you wished to see your son graduate, before he left for another continent, Dean. As usual, you're letting your anger cloud your judgement, and that never ends well for anyone. Remember how much it cost to repair the dry wall?"

"Don't start that shit again, Cas," Dean said exasperatedly, shaking his head.

"I'm just saying, you have a history of allowing yourself to become unreasonably angry, and-"

"Just...shut up. You can't say shit about me or my life anymore. You fucking left me, man"

"And it was for the best. You are obviously a lot better off without me, and I can see that it was, indeed, a mistake to come here today and destroy your happiness with my presence."

"Wait, you think I'm happier now? You think I'm better off without you?"

In the pause that followed, Sam quietly left the room, looking for Jess.

"Are you not?"

"I was a fucking mess, Cas. I still am. I…..I suck at this shit. You left me. Everyone leaves me, and I'm used to it, but you…you leaving me was the worst. My mom left me and my dad. My girlfriend left me when Sammy was born. Sammy eventually left for college. And then you, the one person I thought I could count on to stay with me forever, you left too. The only person I have now is my freaking dad, and he doesn't even live in town anymore." Dean let out a hollow, bitter laugh. "I'm alone in a house that I only see three rooms of. You think I'm better? Go fuck yourself. And fix that fucking tie, I don't know how many times we went through that." He turned to leave, but Castiel spoke, and something in his voice made Dean stop in his tracks.

"Dean, I…..we fought, so much. I thought – mistakenly, apparently – that you would be happier without me, that I was holding you back from finding someone who truly deserved you. You and Sam are the only people I was ever comfortable with, and being with you will always be the best thing to ever happen to me. I'll never forget it. I genuinely thought…..did you ever find someone? I'm sorry, I forgot to ask."

Dean turned on the spot slowly, eyes fixing on Cas, the tears from earlier making a violent return – but for a different reason.

"There was never anyone else, Cas," he whispered.

And that was it. Castiel took a wary step forward, then another, then another, until he was standing in front of Dean, in his 'personal space' –

Dean laughed, batting away the wandering hand.

"Personal space, Cas. Trying to make your dinner here," he protested, green eyes twinkling at his new husband over his shoulder.

Castiel smiled, hands still slowly working their way down to Dean's waistband as he stood behind him.

"Oh, I'm sorry, am I distracting you?" He teased whispering the words into Dean's ear like they were a secret only for him.

It was too much for the mechanic, who quickly spun round, grabbed Cas, and pinned him against the wall.

"Only a lot," he breathed, before his mouth claimed the smaller man's.

Needless to say, dinner was late that night.

- and Dean couldn't bear it anymore. Desperately, frantically, he reached out, hauling Cas towards him and crashing their mouths together like it was the only thing that kept him alive. Cas kissed back greedily, five years of celibacy taking their toll as he groaned and pulled his ex-husband even closer. Dean pulled away slightly, staring into Cas' eyes like he wanted to drown in them – which, in fact, he did.

"It was always you, Cas", he murmured brokenly. "Can't have anyone else. Never tried. Always you"

His words were swallowed by Cas' mouth, which he eagerly licked his way into, drawing out deep, guttural moans from the trench-coat wearing man.

"Dean, I…" Castiel gasped out as Dean's lips made their way to his neck. "Only you, only ever—" He bit off a cry as Dean suddenly bit into his neck, nibbling and licking until a bruise was brought to the surface of his skin.

He looked Dean in the eye, foreheads pressing against one another as they breathed heavily.

"I love you, Dean Winchester. I never stopped."

"Winchester-Novak," corrected Dean. "Like yours. Castiel Winchester-Novak….I've loved you since the day you walked into my garage, you ass, and I can't….I can't lose you again. Come back to me. Please, don't leave me again"

These last words were filled with pleading, and Dean stared into Castiel's eyes as he answered, "Dean, of course I'll come back to you. I'm so sorry, Dean"

Dean's eyes were drawn to Castiel's left hand, which still bore the wedding ring he'd given to him so many years ago. He wordlessly held up his own hand, which still had his wedding ring on it, and rested it against Castiel's face, letting him feel the warm metal. Castiel took a stuttered breath, placing his hand over Dean's to keep it there as he vowed, "I'll never leave you again, Dean"

And with that, they kissed one another hungrily, until they were so entangled with one another that it was impossible to tell where one man ended and the other began.

Sam, walking past later, thought it prudent to ensure that the door was locked, judging by the sighs, sharp cries and breathy moans leaving the room, as well as the handprints that had been slammed against the steamed up door.

FIN
