Just to be clear, Wash's spirit is kind of haunting the ship, she can only hear him and no-one else knows about him.
Serenity was feeling restless, she could feel it. She leaves the menfolk to their Neanderthal-ness and walks her shadowed halls and finally make it to her destination, the bridge.
"Wash, what seems to be the problem, Serenity seems unbalanced" she says to the former pilot
"She does, doesn't she. Ask Kaylee to check the compression coil, or better yet, check the whole engine" says the enigmatic little man, in his quirky voice that only she can hear, incredibly perky for a dead man. At least he gets to watch his warrior woman raise their child, little Mathew Hoban Washburn born seven months after Miranda, and he was a week late. Odd mix of mocha skin, strawberry blond hair and incredible blue eyes, just like his fathers but with that consistently stoic look just like his mothers, five months old and still probably more mature than Mal, then again, who isn't.
"Does she have to, Kaylee and my brother…" she stutters, almost choking
"Can wait, they can't be sexin' if there dead, and then Simon will never know his unborn children" he replies
"She believes there is an obligation to future niece and nephew growing in our mechanics stomach" she answer grudgingly
"Yes you do, now to work, get Kaylee to check up Serenity's engine, kay, or are you gonna rub soup in your hair" she give the place he would be sitting on the bridge the look, the I can kill you with my brain look, she can hear his sigh seep through Serenity's metal walls.
She knows that she needs to interrupt Kaylee and he brother but it was just so gross. She walks down the hallway that houses the crew bunks, she really doesn't want to interrupt them, waves of lust from the bunk that has Kaylee written across the door was knocking her down, she must have bashed into Jayne's door in her trying to get away from the almost crushing lust because he had opened his latch and was staring at her. She grabs his arm and pulls him between her and Kaylee's bunk, her breath shallow, sweat on her brow
"What's wrong, girl" he says in his gruff voice
"Need to get Kaylee to check engine, she's with her brother and, uh…" he turns abruptly and kicks Kaylee's door half a dozen times while yelling
"Kaylee, get yr pi gu up hear, Crazy needs you"
"Qing-wa cao de-liu mang, what is your problem, I'm busy" says a very flustered, hardly clothed Kaylee
"Don't get yr panties in a twist, River need you for whatever reason and couldn't get near enough to nock coz yr sexin's makin her dizzy" she looks shocked for a few second before Kaylee grabs her in a tight hug
"I'm so sorry River, I didn't know you needed me, I'm sorry I was makin you sick, baby, please forgive me" she is shocked for a few seconds, but soon recognises this as normal Kaylee behaviour and decides to answer
"You're forgiven, Sister-in-law of mine. I need you to check the compression coil and if nothing's wrong, check everything else" Kaylee looks confused for a moment
"What's wrong River?" she asks with concern
"Serenity's restless, she want to make sure she's okay, she have recently been reminded of the obligation to you and yours she has, and her need to keep you safe is phenomenal, please help her nerves and check" she asks with solemn eyes bearing into the whiskey eyes of her sister
"Okay River, if only for yr nerves, can't have a restless pilot" she says simply and goes down into her bunk, returning in a few minutes clothed in her patented mechanics overalls and pink skivvy showing underneath and says "I'll be gettin to work ,I'll check 'er top to bottom" she says seriously and disappears down the hallway heading towards the engine room
"Thanks Jayne, you helped her and one day she will return the favour" she says, completely calm even with the odd emotions coming from Jayne that he wasn't even trying to control
"Need me again and I'll be in my bunk" he says, his usual goodbye
"Rest well, wolf" she says as he disappears down into his bunk "you're going to need it" she adds when he can't hear her anymore.
