There were times when everyone still looked at them when they smiled at each other. It was almost disconcerting, but she'd learned by now to ignore them; the moment would pass, the rest would stop looking at them, and things would continue their flow. Serenity would keep flying, and the crew would go about their business.

The astonishment was understandable, she knew. They were very different. He dwarfed her in size, and they argued as much as they smiled. Hell, sometimes they even argued while smiling. He was gruff and violent, and she was insightful and wide-eyed. But what made them fit so well together was that she was violent too, and that, in his own way, he was just as insightful as she was. As odd as Jayne and River being together seemed at first glance, if someone really looked…not just glanced, but really looked...

She chuckled to herself as the others looked away from them, and Jayne raised an eyebrow at her. River shook her head; it wasn't important, and it wasn't anything they needed to discuss. It was only a memory of when the looks had started.

The first time he'd belched, a typical behavior of the 'man-ape-gone-wrong-thing', and she'd just looked at him, and the words 'excuse me' had fallen from his lips. Wash's jaw had fallen, and he'd made some incoherent noises for a few seconds before her Jayne had finally just shot him a glare, and the noises had stopped, only to be replaced by River's giggle. The shock, however, had lingered on his face for a while after.

After that, but not too long after, they had been arguing – over something small and probably insignificant, like many of their arguments – and he had made a point that she couldn't refute. River had just looked at him for a second before nodding slowly. "You're right. I'm wrong." Their audience at that point had been Simon and Kaylee. Simon's reaction had more or less mirrored Wash's, except for the fact that this time it was River glaring and Jayne laughing.

From that point on, people had stopped glancing at them, and they'd really looked. The crew had stopped looking out of the corners of their eyes and wondering what was wrong with the mercenary and the psychic, and had started wondering what was right about them.

And as they looked, really looked, they saw what Jayne had learned long ago, and River had known all along: they fit, and they fit perfectly.
