I don't know how your robots, computers, or androids compare to mine, but this is not a matter of deviousness.
It's simple logic.
You've written about teleport systems, and the teleFRAG as a weapon. It's obvious enough that the two are related, and that eventually their relationship could be put to advantage. That's not the kind of thing a computer brain forgets.
My android did a lot of devious things. She kept her own purposes hidden, primarily because no one ever asked her.
To some degree, she was conducting experiments, and it would not have been proper, in this research, to contaminate the experiment by divulging things the subjects did not need to know.
You may think of it as deviousness, but computers by their nature do not volunteer information. Sometimes you have to pry it out of them with really intrusive devices.
Well, I based Eva and her actions in part off of what little I know of your robots.
Though I do admit that in both her incarnations she makes herself a ‘flesh shell’ that she ends up in.
But how she pulls off the snatch and grab I haven’t thought through yet.
And when the primary Eva finds out, I wonder how upset she’ll be.
