Gabriel smiled. "Well. It won't hurt our cause. But I'm talking about fooling gene sniffers. Look. It's like this.  Every human has a genetic code. Different from everyone else. Your kind don't have a unique code the way that everyone else does. As an engineered being each synthetic has the same genetic structure at first. You're designed to be the same. However inside your blood are nanites. Microscopic robots designed to upon your mental bonding with a person begin to alter your genetic code.  So. For example. Your brown hair becomes blonde. Eyes become green or brown instead of blue. Ethnicity traits such as slanted Asian eyes or kinky African hair are re written into your code.  This is done by reworking the atomic code and the gene sequences and your chromosome pattern via nanites. After once time doing this, normally said nanites are then flushed out of your system and aside from a few telltale genetic markers no one would know you're synthetic."<br/><br/>He paused.  "In order to go out we have to do the following. One. Change the system to think your genetic makeup is that of a normal person. This is not easy. Or two we have to alter your genetic code in such a way the nanites in your blood don't recognize it's happening. Which if done wrong could kill you. "<br/><br/>He looked at her and paused. "The system is so advanced it's able to track everyone on the city. The only way I had to disrupt it wss to use my now useless disruption program. Which sent out a signal to the DNA trace programs that I was In effect a meat popsicle. It also distorted my image from system cameras and other tracers. If we had something like that and the diplomatic paperwork it would make sense to anyone eatching. They'd think we were VIP personal and leave us be. "<br/><br/>He reached for a laptop and got to work. "It's simple. All I Have to do to keep the systems eyes off at this point is flood their system.  I'm going to make the system think the streets are flooded by a couple billion rats. They'll know someone breached tbem. But not whom. Or from where."<br/><br/>He set to work. If all went well they wouldn't have the system back up until the pair of them were already home. He began to change into something more formal looking.
