Spoiler markdown is annoying, and will only be here for a week. Don't read further if you're not up to date with Westworld.
It has been revealed in episode 9 of Westworld that;
...Bernard is actually a host 'resurrection' of Arnold, made in his likeness.
This is confirmed through the photograph and flashbacks of Dolores talking to him in the secret basement of the hidden home.
But, given the fact that all the employees speak of and semi-mythologise Arnold, why is it that
No one seems to have noticed that Bernard looks exactly like him? We know there is documentation and photos of Arnold (Ford has one), so given that Bernard is seemingly free to come and go as he pleases why would no one from the 'real world' recognise him as Arnold's Doppelganger? If Bernard never rotates out of the facility, why has no-one noticed he doesn't ever leave? the picture of Ford, his father and Bernard would indicate that the Bernard/Arnold host has been knocking around the facility for a long time (The flashback of Ford activating the machine looks like a much younger Ford, I'd speculate 20 years younger minimum). Are we really to believe that Charlotte Hale, a board member, has no idea what Arnold looks like?
Has the show addressed this glaring plot hole at any previous point?
Given the events of S02E02, I'm opening this one straight back up wth a bounty attached. Arnold was clearly not a reclusive, he should be recognisable to outside interests: and yet still is only known as 'Bernard' by external forces in Season 2. Are there any interesting theories why?
