A loud alarm began to reverberate through the building. It was muffled but still discernible in the stairwell.
Atlas stumbled back to his feet after the explosion and heard the alarm.
"s***, they're on to us already?!" said Atlas. He ran back up the stairs and tried to open the door so he could see if any guards were coming. The door had been sealed shut.
"Duncan," shouted Atlas, down the stairs, "can you hack the lock to this door?"
After a few seconds, Duncan shouted back, "The system's down! I can't access any of the locks right now!"
Atlas stood next to the door a minute and listened to the alarm. That's not an intruder alarm, he thought. That is a fire alarm. He ran back down the stairs to meet the others.
"I don't think they know what we're up to, guys," said Atlas, with a hint of fear and disgust in his voice. "That's the fire alarm. Did someone trigger it as part of a diversion?"
Duncan and Shell both shook their heads.
"Could there be an actual fire? Maybe it was from whatever just caused that loud noise and shaking," replied Renk.
Atlas sat on the steps. He began to feel nauseous.
"Those smoke grenades aren't incendiary, right," Atlas asked Elise.
Elise shook her head. "Of course they aren't. You should know that, being military," she replied.
Atlas wiped his brow. "Right, right, just checking. We only used non-lethal weapons to blind and confuse them, I know."
Jess shrugged and looked at Atlas, having a confused look on her face. "I'm sure it has nothing to do with the explosion or the fire alarm. Remember, we're in a weapons manufacturing facility! Maybe a test just went wrong somewhere nearby," she said to Atlas, trying to reassure him.
Atlas stood up. "I'm sorry, everyone. It's just... sometimes... I get these flashbacks, y'know?"
Renk impatiently gestured to everyone to follow him further down the stairs. "Come on, we don't have all day here," he growled. "We may have sealed 'em in the auditorium but they won't stay sealed forever."
Atlas caught up with Renk as they continued to descend the stairwell. Renk patted Atlas on the back. "It's going to be fine, buddy," said Renk. "Just focus on the mission."
