Something that was meant to happen, but there was always an outside force that kept them apart. If only we did not have that cliffhanger and Josh's promise to never reveal what would happen at the end of the story. "I am Locutus of Borg. Resistance to Summer is futile."
I like the Rayne stuff. Its cool to me because I already imagined that if there were many more seasons of Firefly that Jayne & River would eventually be a couple. I'm on twitter @LMennellFans & @JP_1085
