When the company sends Brandy a way for her to communicate with Clara again, it's not even Clara she's talking to, it's Dorothy.
At the start of the episode, Brandy researches Dorothy Chambers before landing the role of Alex and watches a video. You can see the company recreated the footage (from the ending) of a video called Dorothy Chambers Screen Test, so it's not even a version of Clara she's talking to, but a version of Dorothy playing her role as Clara. It's not even a semblance of the character Brandy managed to fall in love with, but of the actress who hasn't even started playing the role in the movie. Same face, but totally different person. Makes the ep's ending more bleak in my opinion.
