Seen posts and peeps around asking why Guinevere hasn't tried to use her strenght to escape and harm who hurt her just like how she did with the Knight Mecha in the lower labs (assuming it is the same android everytime that escapes, I suppose it is given it is said that it's an old unrecognizable model of the android).
My guess is that A) she has a programming that keeps her from harming all humans altogether (even if it's for self defense), or B) it's something still in her programming but unrelated to it.
For now I'm leaning on the first option because, given the fact that she was also damaged, she could have tried to protect herself from being scrapped and go rogue against Frankie and Sparky, as well as Andi. Because lets face it, despite the girls having good intentions in repairing her, it was still because they wanted to make money out of her by either selling or give her back to who lost her, much like Sparky with scrapping her. And still she did not move to do anything but smile as the minutes amd hours went on when she was with them.
The only time she DID in fact did something was to warn the HUMANS, not just herself, of the robot that was going after her.
And ultimately "waking up" to fight and destroy the thing, while carrying the injured girls to a safe spot (in a manner of speaking).
So yeah, I don't think she can ACTUALLY hurt humans, nor is she allowed to, if she could she would have probably snapped on Olivia way sooner instead of escaping and leaping off the tower at the start.
But the moment she can hurt someone, I don't think she can be stopped so easily.
