I felt a little confused, firstly, at why Weyland-Yutani would have synthetics specifically built for acting like human soldiers. It's one of those things which is often in the games, but never makes much sense. If you're wanting what amounts to a weaponised drone, then there's no point in making it so fragile and humanoid. Something like that should look properly armoured and like Skynet designed it. Something you really
could picture being commercially successful by being put on battlefields or corporate security detail.
It never felt terribly logical when it happened in '
Book 1' and it doesn't feel very logical here.
Nevertheless, what
really made me WTF, is the synthetic who just, as was pointed out, decide to go against its very programming. Computers don't work like that... Directives are just that: Directives. It would go about its business until something contradicted those directives. It can't just go, "Yeah, don't want to do that..." That's the whole point of being a walking computer!
And, to make it stranger, the lead character even
points this out to the readers and then no longer seems to care.
Now, if I was being sneaky, I might think to myself that this is not, in fact, as contradictory as it appears. That maybe the synthetic is lying and there's some kind of dastardly plan underway. But having the lead character not realise how much of a whiff of bullshit that gives off, makes her seem... Not exactly the brightest.
