episode to capture Klingon Torres' respect for Human Torres. Dawson added that the episode's central theme was "learning to respect the parts of one's self that make up the whole person". "Faces" was noted for establishing Torres' ongoing inability to reconcile her human and Klingon identities, in "the most literal battle". Biller disagreed with the episode's resolution, arguing that Torres should remain human. He felt that the episode should have a longer impact on Torres' character development, and believed: "[w]e couldn't get to the end of the episode and say that Torres has now resolved all her issues and is at peace with herself". This story arc continued in the later episodes "Day of Honor" and "Prophecy", in which Torres eventually accepted her Klingon heritage. Actress Joy Kilpatrick was cast as Dawson's photo double. Dawson described having a great working relationship with her stand-in. Discussing Kilpatrick, she said, "I was about to tell her what I was going to be doing so she could give me the beats that I could react to properly" and found her to be supportive and intuitive. Kilpatrick was not credited for her performance in the episode. Kolbe noted that the episode used a lot of visual effects, specifically to create the illusion of the two versions of Torres. The casting of a photo double allowed Kolbe to avoid relying on split screen. The scheduling was carefully planned to account for the make-up used for both roles. Dawson described the prosthetics for the Klingon version of Torres as "a forehead, nose, and teeth". She felt that the look was not as sophisticated as the character's normal appearance as a half-human/half-Klingon because of the lack of skin tones and nuances of the facial features. While Dawson's make-up typically took two hours to apply, the full Klingon prosthetics took around three hours. To save time reapplying the make-up and prosthetics repeatedly, each day's shooting would concentrate on one of the two characters, and switch the following day. Dawson compared the experience to repertory theatre. Despite the casting of the photo double, and attention to scheduling, Kolbe was disappointed in not being able to shoot more scenes with the two versions of Torres in the cave, but understood the frequent use of the split screen could negatively impact the production cost. After the episode had aired, Dawson called her parents to ask their opinions. They replied: "you were
