Jayne fights a lot.
Fought, at first, to survive. Eldest child in a large family, had had to fight hard to get out. Fought to make it out in the big scary black. There was always someone scarier, bigger, stronger. Fought not to grow fond of anything, anyone. He'd thought he'd won.
He'd at least done a far better job at it than any other on board.
Zoe was a ruttin' mess, existing without the little man. Kaylee 'n the doc were practically nauseating. He wondered how Zo' put up with it, at times. 'nara's not whorin' out as much as she used to, 'n Moony hangs 'round her more often. He's stopped callin' her that out loud. Kid's tryin' her hardest and she ain't done crash 'em all dead yet. 's a start. Figures Mattie's 'bout 'er age.
Jayne fought so hard, he knows he's losin'. How could he keep himself from caring 'bout all them women on his ship? 't figures, all of Shepherd's speechifying come back 'round to bite 'im on his muscular buttocks.
"Got me word you've a nice crew of ladies here. Might like some one-on-one time with 'em." Cocky bastard smirks, guns trained on his Captain, his women. Zoe pales, hand set over rounding belly that's not yet noticeable, and River whimpers. It's the whimper that sets him off.
Mal blinks up at him once he's done. He's silent, strong, gun still withdrawn. He can see the Captain's hands shaking. He needn't have worried such. There's no way he'd let any of 'em hun dans hurt any of his crew. His family. Mal nods in acknowledgment, and there's no need for more words.
Captain drops to his knees, checking on his crew. His heart might not be as big, but even it skipped a beat when guns were trained on that tiny slip of a girl. He coulda sworn Cap gained another whole 10 years at that sight.
Jayne had thought maybe there'd be a time for him an' crazy, but things worked out differently. He's not the one she's been makin' sweet eyes to, an' that's just fine. Ain't likely he could find one woman to settle with, 'n that'd just complicate things. He's not keen on leavin' Serenity now.
Jayne fights a lot, but now most of his fighting is for Serenity an' the rest of his family. He figures he ain't never been one for lost causes. Shepherd'be proud, he thinks, as he says a prayer at night.
Comes a time, man's gotta stand up 'n fight for his own. 'n Jayne plans to fight.
