Mal believes.
He's grateful for a lot of things. He's got a solid ship beneath his feet, a crew to rely on and miles and miles of space ahead. Sure, he blames the man up there for all of his losses, but he's indeed grateful he's still got such loyal people to fall back on.
Shepherd Book had asked him to believe in something. He can say he finally does.
He believes in Serenity, his home, his family, his heart. His everything. He believes in each and every one of his crew. He mourns, it's much obvious he does, Book and Wash and even Mr. Universe hang over his head.
Fortunately, he's found something to believe in.
Zoe, for example, and the little human form she's carrying. River's made that abundantly clear, even if Zoe ain't said it out loud just yet.
Jayne's proven himself to be much trustworthy: he believes the man has found a home, and a family. More importantly, he's accepted it.
Kaylee and Simon, he hopes, will start sharing some of their sunshine. He believes they will, soon, or he'll have to start banning them from common areas.
He used to believe he had a future with Inara, but now sees bags, boxes packed again and he finds himself unsure. Something's changed, the reason is him, and he ain't exactly sure if he ought to be glad. Inara don't seem to mind, she only smiles, and he wonders if she believes the same. He believes she won't be comin' back this time.
"Storm's getting worse," he breathes, eyes fixed on the front.
"We'll pass through it soon enough," she echoes, and it only startles him a bit. He smiles, it's hard not to, and feels the wrinkles form on the side of his eyes. She's so young... A part of him breaks for her.
She's given him a reason to believe, nothing more than a broken child, shaped as a fancy weapon, then sought after 'cause she was better 'n they'd expected. Mal's found he believes in much more 'n he would've ever expected to. He still holds his oldest beliefs close to him.
Mal believes, knows, they will rise again. And, when his eyes meet hers, he truly believes she'll be by his side when the time comes.
Mal believes he'd like her to be there.
