So I was wondering about the entrance lady host who was helping William. She mentions to William for him to ask the obvious question if she is real. From her words and actions in the scenes, she is obviously not human, a host. Since she is one of the park's entrance hosts, they get the question often.
But this makes entrance hosts totally unique from regular park hosts. They are hosts aware of the predicament they and their fellow hosts are in. They understand that they are not real, yet continue as if they were. Do they know that they are just used and do they not care about the hosts in the park who are killed everyday? How much do they try to influence how visitors hurt or help hosts in the park? If a visitor kills an entrance host, do they get repaired just as normal park hosts? Do they routinely keep memories day to day unlike park hosts?
It would make sense that their knowledge of their lot in life is way more than park hosts, like Delores' father glitching just from looking at a pic of an unknown world.
