In his bunk where he'd retreated to hide after the EVA incident and so thoroughly kissing River, Jayne heard Kaylee's happy announcement that the Captain and crew had returned.
That meant they were headed for the Casino Sky-Plex.
Still got a few days, he thought to himself.
You need to tell them
What. The. HELL?
Now she seemed to be in his ruttin' head!
He waited; but, when he heard nothing else, Jayne pushed it aside as paranoia and laid down on his bed.
Better to hear it from you
"Gorramit!" he yelled and knocked everthing off of his night stand. He jumped up and up-ended the chair, then kicked it savagely. Roughly, he moved on to strip the covers and sheets from is bed and heaved his pillow at the ladder.
With a grunt, he reached uner the bed to grab ahold of the frame and flipped it, mattress and all. Still unsatisfied, he unmercifully kicked at the padding and flung the empty frame sideways across the room.
Dropping to his knees, he then pounded fiercely into the thin mattress, brusing his hands.
After a few minutes of this brutal punishment, Jayne sat down heavily on the cold floor, knees bent, and repeatedly beat his head back against the bulkhead beneath his weapons.
Then, Jayne Cobb--Expert Marksman, Tough Mercenary and Big Damn Hero dropped his head onto his forearms as they lay draped over his knees...
And started crying uncontrollably.
