A/N: This is a the first in a series of songfics, but since it's illegal to use lyrics in a fic, I have simply titled each fic by the name of the song that inspired it. This one is based on "In My Veins" by Andrew Belle

They had never made sense on paper. They had never been a cliche', they had never been the 'average' couple. A cop and a writer. A fan, a muse, a hotshot, a womanizer, a father, a daughter, damaged, veneered. None of it made sense. They shouldn't be where they were. They shouldn't be them at all. They should never have crossed paths. They should never have existed. And yet, they did.

They had been told they would never last. They had been scoffed at, told that a writer marrying his muse would ruin the illusion, that she would no longer inspire him, that they would then fall apart. They had been told that they would never stay together, that their love was not going to keep them afloat. That it would ruin both of their lives in the end. People sneered and whispered, they talked and laughed. But, Kate reflected later, maybe that was exactly what had brought them to where they were today. Maybe that was what had kept them from falling apart. There had, after all, never been two people more stubborn than Richard Castle and Katherine Beckett.

Their life together had been messy; there had never been much sense or simplicity in them. They'd been some kind of crazy love story just waiting to be told, full of twists and turns and crazy moments that only they would be insane enough to dive into. They were twisted in a way; the thing they had met over, after all, was murder. He was a writer; she was a cop. How could this have happened? How did they make it?

Neither Kate nor Rick regretted a moment. Well, maybe there were a few things they could've done differently, but in the end, it all came to now. It all brought them here, to where they were; exactly where they'd been trying to get to. Every time he had thought he would lose her, ever moment she had debated with herself over how much to let him in, every time they had said 'Always', every tomorrow they had faced together; without it all, they wouldn't be here, in their Tribeca loft, their belongings a mixture of his and hers, compromise and mingling. All of it added up to be some part of them. Of their story, their legacy.

They were more than their mistakes. They were the ones that could never fall apart. They'd come so close, so many times, that now, it had become impossible. He would follow her to the ends of the earth. She would do anything for him. Their love and their passion and their hearts and minds and lives; it was all one now. They were one. And they loved every moment of it. Kate thought back to the wisest words she had ever heard; the best advice, from the most wonderful man. 'For us, there is no victory; only the battle. And the best that you can hope for is that you find somewhere to make your stand.' Roy Montgomery's words had always rung true. When he had first said that to her, Kate's first thought was of Castle; her partner, the one she knew would always be by her side; unfailing, unflinching, unquestioningly loyal to her. And she had thought that the only thing Roy was missing was the fact that those extremely lucky would find someone to stand with them. Like she had. This was them. This spot had become not only hers, but theirs. This was their spot. This was where they stood; side by side, hand in hand, ready to face the world; tomorrow, together, Always.
