(Why does he have to make a problem out of something easy? xD And how is wanting a knife a female thing in any context? :P)

The android looked up when a question was asked, though he didn't answer immediately. "Prices for weapons are not a part of my programming. Please wait until the owner returns." He finally answered, then went back to his work. The droid really was just a repair robot that had been repurposed. He was pretty advanced, sure, but he still relied on the programming of his brain chip. Which was nowhere close to what Eve had.

A minute later a human finally entered the shop, holding a cup of coffee in one hand. "Customers! Great! Interested in cybernetics, or some weapons?" He asked in a friendly tone. The man looked nothing like what you expected. Frail, short blond hair, round glasses, and not looking like he had any cybernetics himself. The most notable feature was a dot on his forehead though. Kind of like a tattoo. "Oh, and since you're new I'll explain my security." He looked at Eve, pointing at one of the guns. "You there, android, try pointing a gun at me." Eve raised a brow, but then figured what the hell why not? So she grabbed a random gun and aimed it at the man. It didn't have any clips anyway. But right away the worker android sprung into action. With great agility it jumped over the table, blades springing from his arms. "Customer, you have five seconds to lower your weapon." It spoke. Eve smirked, lowering the weapon and putting it back again. So he's not just a worker, but also security. Nice touch." She mused, going back to rummaging through the knife box.

The man turned to Jurgen again, a kind smile on his lips. "As you can see, I have excellent security, so I'd like to keep things friendly between me and my customers to keep things from escalating. Now, what were you looking for?" Eve had noticed the dot on the man's forehead too. And she remembered that her creator, now known as Professor Nova, had the same dot. Couldn't just be a coincidence right? But she'd ask him about it later. First she had a particular blade to check out. One that seemed to suit her needs perfectly. It looked like it was made of hardened titanium. And though it was dull now, with a grindstone she could easily sharpen it again.
