Nick was wrestling with a particularly difficult calibration set with his tech crew’s assistance, attempting to match his eye movements to the cannons as he heard the ungodly racket. A cascade of tools and angry yells causing Nick to remove his helmet and slide down the side of his fighter. This, while a boring sit and wait period, should not have this much tension. Likely it was nerves about the first possible engagement getting to the crew, maybe a planet born anxious about all the metal and lack of trees. In either case, it could not stand. 

Flexing his hands, he motioned to the techs that he would be back, as he looked towards the Isorlai and the terran as Gurjan berated the woman. While he would admit that most Isorlai had hot streaks and were temperamental, this was not acceptable. Walking forward he ran through his list of options. It was likely not his place to do anything, but nick had a history of walking the fine line of "rules and Regs" 

He could back up Nyx, and tell him to back off, hoping it didn't escalate. 
Or,
He could cut to the chase and strike him, but that could get him sent to the brig, which would be fine, if it wasn't for the possibility their drop out of hyperspace would be into an ambush. 

What he could not do was ignore this, it just wasn't in him to look away.

Fortunately, the colonel was on Gurjan before Nick could take ten steps, her stance and aura dissipating technicians and floor crew without a word or gesture. It was her eyes that did it, the face was a mask of disappointment, but the eyes betrayed her true emotions. The glare demanded that this be dealt with quickly, and if it came to blows, would end brutally. 

"Lieutenant Wallon, Please explain to me why in the coldest pit, you are kicking Chief Grayson's tools around the hangar deck, and why Lieutenant Miles is currently hiding in the Head. And I want the truth, mister. No bullshit; we seriously do not have time right now."
Nick knew that tone, visibly relaxing as Erien waited with all the authority as if she wielded the sword of Damocles herself. Confident that the colonel was in control, he backed quietly away, and continued to watch as Gurjan attempted to make himself as puddle like as possible before the C.O.

Nick felt small bit of contempt for Gurjan, marking him as a kind of bully.  Having been bullied enough for being a spacer Isorlai, and therefore “tamed” or “soft” as a child, Nick despised bullies, and the fact that Gurjan shrunk immediately before the Colonel made it worse. It also marked him as a coward. After silently observing a few moments, making sure he wouldn’t need to break up a brawl, Nick returned to his fighter.
