I agree about Bernard . My thinking about it being either Ford or no one is this conversation , from episode 3 . Read it now knowing that Ford has a secret robot house with his dead family , and that he is talking to Bernard , who is a robot I bolded the important linesBERNARD LOWE The idea that primitive man believed his thoughts to be the voice of the gods . I thought it was debunked . DR . ROBERT FORD As a theory for understanding the human mind , perhaps , but not as a blueprint for building an artificial one . See , Arnold built a version of that cognition in which the hosts heard their programming as an inner monologue . with the hopes that in time , their own voice would take over . It was a way bootstrap consciousness . Ford sits down behind his desk . But Arnold hadn ' t considered two things . One , that in this place , the last thing you want the hosts to be is conscious , and two , the other group who considered their thoughts to be the voices of the gods . BERNARD LOWE soft laugh Lunatics . DR . ROBERT FORD Indeed . We abandoned the approach . The only vestiges that remain are the voice commands we use to control them . Ford stands back up . But , for all his brilliance , I don ' t think Arnold understood what this place was going to be . You see , the guests enjoy power . They cannot indulge it in the outside world , so they come here . As for the hosts the least we can do is . make them forget . BERNARD LOWE But . some of them are remembering accessing fragments of Arnold ' s code . If I may ask , what happened to him ? DR . ROBERT FORD Well , he died . here in the park . His personal life was marked by tragedy . He put all his hopes into his work . His search for consciousness . consumed him totally barely spoke to anyone . except the hosts . In his alienation , he saw something in them . He saw something that . wasn ' t there . We called it an accident , but um . I knew Arnold and he was very . very careful . Anyway , the update should prevent any further voices , but you will let me know if any of the hosts display or exhibit any unusual behavior , won ' t you , Bernard ? BERNARD LOWE Yes , of course . Bernard starts to leave . DR . ROBERT FORD Good . Oh , Bernard ? Just don ' t forget . the hosts are not real . They ' re not conscious . You mustn ' t make . Arnold ' s mistake . BERNARD LOWE soft , puzzled laugh Why would I ? DR . ROBERT FORD Well , forgive me , but I know that the death of your son Charlie . still weighs heavily on you . Bernard nods and leaves Ford ' s office . He ' s telling Bernard , who is a host , to not think the hosts are real , and that Arnold only spoke to hosts . Ford has been seen talking 1 on 1 with Teresa whom he killed , and the MiB who is a special character , being someone as a sort of counterpart to Ford in some sense also we don ' t know if he ' s a host I don ' t think he is though . But otherwise , other than group meetings , he only talks to Bernard all the time , Old Bill , Teddy to give him the Wyatt update , and Dolores . Charlotte also said Teresa was careful , although she said loyal and careful not very very careful . Anyway , just seems like Ford is talking about himself , while essentially talking to himself , since Bernard isn ' t real , although that ' s debatable . Telling Bernard not to make Arnold ' s mistake while doing what Arnold did . Then again , maybe he doesn ' t think his fake family is real . but how could you not ? He recreated a whole house and even a dog .
