Jayne hears all the arguing and asks them why "they're fighting at a time like this." But he doesn't mean it in some namby-pamby, we-all-must-work-together-in-a-crisis way. He tells them they're going to use up all the air.
Blue-tinted, bleeding Mal continues making his way slowly down a corridor, leaning against the wall for support. An alarm has gone off, and a computer voice warns Mal that there's a life support failure. That sounds like the most unnecessary ship warning imaginable, second only to, "Warning: the ship has been blown into pieces." Like they wouldn't have noticed by now. The computer voice alternates between that message and something in Chinese ("The white zone is for loading and unloading only").
The camera pans down a corridor, and the lighting shifts from blue to yellow-green. Mal stalks down the corridor, shouting for somebody named Bester. He's the alleged "genius mechanic." Mal's upset at the news of another delay of some sort. He makes it to the engine room, and is startled and shocked to see that Bester's in there having sex. Mal mutters something in Chinese ("This better get us that 18-34 male demographic") and turns away. He has to call Bester's name out several times to get his attention. Bester finally hears him and stops his extracurricular activities. He pulls on a pair of pants and comes out to the corridor to find out what the problem is. Apparently, the problem is that Bester is an incompetent slacker. He's the Ty Pennington of the future. Mal exposits that they've been stuck where they are for a week now, and they've got work waiting for them elsewhere. He asks Ty XXXVIII if there's something wrong with his bunk, meaning, "Why are you screwing women in the engine room?" Ty XXXVIII explains that the girl he's boffing is turned on by engines. That's an interesting fetish. I can only imagine the erotica for that one. Actually, if I did a web search, I probably wouldn't have to imagine, but I don't want to know. We also see that Ty XXXVIII is very well built when it comes to the muscles. Ah, surfer dudes: pretty to look at, but about as useful as balloon animals. Mal orders Ty XXXVIII to get his "prairie harpy" off the ship and get them back into space. Ty XXXVIII insists that he can't because the "secondary grav boot" is shot.
