The symbionte doesn't teach
you in the classical way. It basically reverts your memory patterns into it's own storage, so you know
how to perform surgery. Think of it like a module or program. YOur computer doesn't know how to do CAD stock, but if you install a CAD program, it does. It works pretty much the same way, but "portable", as in, the Ijad is the storage device, and your HDD doesn't take the program. You run it from USB.
