Jason slowly walked towards the guards, near the entranceway. There was the second alarm signal.
That's when he heard the engineer call in his vessel. He muttered under his breath. "Nobody ever thaught that person any manners, it would seem." he thought as he activated the ship's intercom system from his current position.
"You'll have to excuse me for a minute... natural urges tend to always happen at a bad time..." he said, his voice taken inside his vessel. It wasn't a big one, but big enough to have some rooms and make all that explanation plausible. "I'll be there in about a minute..." he added as he walked right next to the guards.
He opened a compartment on his belt, and quickly closed it, hoping nobody saw it. He placed a little bit of semtex-4 explosive on the side of the alarm device, and ran back into his ship, unheard.
He walked passed the engineer, and realized it was a female. Not that he had anything against it. But it's always a nice thing to know. He was really bad at flirting, but who knows, maybe his luck will play this time and he'll get some more spare parts for free?
He opened a door and stepped in, quickly, without being seen. He deactivated his armor's cloacking device, and removed his helmet, which he slung under his left arm.
He re-opened the door and walked about 2 meters and greeted the engineers and the guards.
"So, I guess you're the cavalry, huh? Thanks a million for helping me out! I only had 15 minutes of canned air left in this suit..." he said, smiling.
He extended his right paw and smiled at the engineer. "I'm Jason. Nice to meet you, miss...?"
