"How’s your roommate?" Sam asks as he dropshimself on Dean’s bunk.
Sam raises an eyebrow. "Why don’t you request areassignment?"
"Because he always cleans his mess, doesn’t snoreand sometimes does my laundry. I know there are bigger assholes than him. LikeZachariah for example," Dean shivers to demonstrate how disgusting hefinds the idea.
"Still, there must be a better match foryou." Sam looks guilty. He’s been Dean’s roommate ever since the academy.Until he married. Expecting a child qualifies Sam and Jess for better housing in a different part of the spacestation. Dean doesn’t envy them. Well, maybe a little, but he doesn’t blame Samthe way Sam blames himself.
"It’s okay," Dean dismisses Sam’s commentwith a shake of his head. "We barely see each other anyway."
That’s not exactly true. They meet at their room andthey meet at work. They almost always clash. All the engineers are assholes andlook at the pilots as if they are a lesser species. Which is bullshit becausemost pilots have almost as much technical knowledge as engineers, they’re notmeatheads.
But Castiel is worse than all the other engineers Deanworks with combined. He has no sense of humor, he’s always grumpy and he makesit his personal goal to make Dean feel stupid at least twice a day. Also, he’sstupidly hot which only makes Dean angrier.
"You ready?" Sam asks as Dean adjusts hisjumpsuit.
 "Have you read the last check report?" Casasks as he hands Dean the tablet.
"Of course I did," Dean grumps. At leastmost of it.
Cas squints dubiously and proceeds to tell him what heshould be careful about. Dean rolls his eyes. "I know every noise Babymakes, I’ll know if there’s something wrong with her."
"That’s adorable, yet irrelevant. Read the reportor I won’t let you out of the dock."
"Asshole," Dean mutters, opening the file.
He frowns when he realizes Cas hasn’t beenexaggerating. There’s a problem with one of the ODT nozzles which might causeproblems when maneuvering in high speed.
"I ordered the parts but for now you’ll just haveto be careful," Cas says as ifreading his mind. Dean nods and hands him the tablet.
"It’s okay, she won’t let me down."
The Impala is an older ship, but she’s in mintcondition and she’s undertaken some tweaks. Where the new ships go for refined,she’s a brute force. Ideal for the part of the quarter they’re headed to today.
"Just don’t tinker with it, I don’t want youmessing it up like the last time," Cas warns.
Dean rolls his eyes. "It was once and thepart was faulty."
"It was just once because I took away yourtoolkit so you couldn’t try again."
"I’ve been fixing the ship before you evenstarted the academy, you-"
"Come on, Dean! What’s taking you so long!"Sam shouts at him over the dock.
Dean lets out an exasperated sigh and jogs to theship.
"Good luck," Cas shouts after him. Deanreplies with a mock salute.
When he gets in, Sam’s already there checking hisequipment. Dean flops into his seats and starts the pre-launch check.
"Let’s go, Baby," he says with a grin andtakes off.
