Plot summary
Bernard is distraught over having been ordered to kill Theresa. Ford promises that he will erase Bernard's memories. Theresa's death is classified as an accident, and her industrial espionage is exposed, as is her manipulation of Clementine. In light of the revelations, Charlotte is forced to reinstate Bernard as Head of Behavior. Bernard asks Ford if he had ever ordered him to hurt anybody other than Theresa. Ford replies he had not, but just before Ford erases his memory, Bernard has a vision of himself attacking Elsie.
Charlotte uploads all of Westworld's data into Peter Abernathy, Dolores' previous father. She orders Lee to program Peter to smuggle himself out of the park with the data.
