In episode 9, Anna tries to bliss a human. She is elated that she can control humans the same way she does Visitors. Now she simply has to bliss the humans into listening to her in order to gain total control of Earth.
If aliens were to come to Earth, do you imagine they would be peaceful or manipulative and treacherous like Anna, what would you do? Would you trust them until given a reason not to or would you distrust them until proven otherwise?
