As Nick was scanning a video feed of the aircraft making its emergency landing all hell broke loose in the command room. "What the fuck-" was as far as he got before he hit the floor beneath his console to avoid a hail of bullets flying around the room as several of these normally calm and collected agents went from uneasy to completely fucking insane in seconds. Some tried to regain order while others fled the room or ducked to hide under their desk. The only change Nick noticed in himself he could attribute to adrenaline as much anything else; he felt more paranoid, but that was probably a good thing to be when he might get shot at any moment. As he unholstered one of his own guns he thought he felt the floor of the carrier quake.
While the world was going crazy around and below, only the automated voice issuing from Fury's command console remained calm as it coolly informed him that there was a breach in the helicarrier's structure. An explosion, he'd felt an explosion. Son of a bitch. Fury rolled into a crouch and lifted his face enough to study the panels and see on screen a flashing red light on the helicarrier schematics the A.I. program had helpfully brought up. Fury had to duck down again to avoid a bullet to the head, then he was typing in more codes, overriding the system to try to set the carrier on a course back towards sea. Whatever the fuck happened here if they were going to crash, at least they could do it over the water.
Nick roared a futile, "EVERYONE CALM THE FUCK DOWN!" which only seemed to have a minor impact on a few people, then he made a run for the closest exit to go and assess the damage to the helicarrier and find out what the fuck was causing it. He burst into a hallway into a run, dodging his own people who came flying at him with weapons drawn, stopping to take down those he had no choice but to fight, and then moving on. His agitation grew worse the closer he got to the point of explosion, but he still seemed able to keep a mostly level head. What he found when he reached his destination was a big hole and some asshole he didn't recognize. "Who the fuck are you?" Fury demanded of the stranger, his gun raised and aimed at the man's head.
