I ' m not arguing the BernardArnold but I wonder why you would create a lookalike of someone who has been completely wiped from the parks history ? It ' s more likely that if Bernarnold is true that Ford managed to upload Arnold ' s character profile into a new host that doesn ' t resemble the man at all . If you add in that Ford presumably killed Arnold it makes even less sense to think he would reconstruct an identical host that we can assume would be as recognizable as someone so integral to the parks creation . Ford may have the ego to want to do this , but he has shown he ' s too smart to play his hand so loose . This would alter how the basement sessions between Bernard and Dolores are interpreted . Just as a lesser offer of support for this is that since Arnold built Ford ' s family it stands to reason that they would recognize his physical manifestation in the form of Bernard . I honestly am not fully convinced of my own argument , but I can ' t quite come to terms with the inherent laziness of Bernard being a physical copy of Arnold .
