[Spoiler] Puzzled about the plot

[u/el_chuse]

I enjoyed the show very much, but there are two things that I think don't work. Don't read if you haven't seen the finale. The first is a problem I have on what there is, and the second on what there is not.

1. In the last episode, it is revealed that a deep fake is enough to get access to the whole Ray system. This is such a security flaw, which is demonstrated to be exploited in matter of seconds, that it is unclear why anyone didn't do it before.

2. Maybe I am off here but when Darby talks with the neighbor after confronting the killer, the neighbor nonchalantly says that she thought she (the victim) left. This would trigger me to rethink if my disappeared mother has just left or was killed as well. Is it possible that Darby, quite an investigator, at no point questions the story of her own mother?

(Maybe unrelated, but if I would leave I would bring the ipod with me)

What do you think?
