He moved the duffle bag onto his desk, then opened one of the desk drawers and pulled out a handful of gadgets. He was about to take a seat and get to work, when he suddenly stopped. The raccoon dug through the pouches on his toolbelt, searching for something.
"Ah crap, did I leave it on the floor again?" he muttered to himself. Jake turned back to the duffle bag, and dug out the small personal computer he wore on his wrist. He put it on as he walked towards the door, powered the computer up as he opened said door, and stepped over the threshold. As he turned around to close the door behind him, he looked into the room, directly at the glowing green eyes of his intruder, and smirked. Then the door slammed, and everything started happening at once.
One of the devices on the table beeped. It was a solid gray cube, its only feature was a screen, on which the word 'On' helpfully flashed in green. Suddenly, the windows looking out of the room onto the floor of the warehouse seem to shimmer, white particles floated and contorted past the glass. Jake had devised this bubble shield as something of a panic button to protect himself in the instance he came under attack. It served just as well as a prison for the intruder now trapped in the office. No way in, no way out.
At the same time, white noise started broadcasting across all frequencies, jamming all wireless communications. Well, that wasn't quite true: there was one frequency he didn't jam. His. From the safety of the catwalk, outside the bubble shield, Jake tapped a button that had popped up on his computer's touch screen. Gas started to flood into the office from small hidden vents. When Jake further developed his technology, he'd realized that having shields was all well and good, but he needed ways to deal with any potential threats as well. Thus, gas for non-lethal attempts, and a number of turret sentries for lethal ones.
He tapped another button on his wrist computer, and another of the gadgets on his desk sprung to life. It was a small, portable speaker. The shield bubble was completely non-permeable. That meant that air couldn't travel through it - otherwise the gas could leak out - and thus he couldn't directly speak to the intruder trapped in the office, nor could they speak to him. But he could taunt them electronically all he liked. He brought his wrist close to his muzzle, and spoke.
"That's diethyl ether," he explained, his voice coming out of the speaker on his desk, "It's a potent knockout gas, and it has the added bonus of being highly flammable. You break any of my toys while you're in there, it'll spark and ignite the gas, you die. You do something stupid like shoot a gun in there, the powder ignition will ignite the gas, you die. Hell, you move around too much in there and build up a static charge that sparks, you ignite the gas, and you die. So be a good girl and go to sleep, and maybe you'll still be alive when you wake up."
"Did you really think I didn't see you?" he questioned, "Or hear you, for that matter? Newsflash, raccoons can hear the noises made by earthworms as they burrow through the ground. Or did you think these fuzzy triangles on my head are just for show? My hearing goes far beyond what a human is capable of. My eyes, too, but that's more of a personal touch."
Gloating finished for now, Jake turned off the speaker. He turned away from the closed office door and proceeded down the catwalk, before descending the stairs back to the door. Only an idiot would come alone and completely without backup. That meant the raccoon likely would have another intruder to deal with before long. Best be prepared.
