(Julie Graham), who has his mother held captive. He puts his intelligence to good use, and with some long-distance assistance from K-9 (who is based in Oxford), he defeats Ruby and saves his mother. He also appears in the Series 5 opener, Sky (2011), on a web cam, his clothes subsequently being lent to Sky Smith (Sinead Michael), another genetically-engineered child who becomes Luke's adopted sister at the episode's conclusion. He makes a final appearance in the series finale, The Man Who Never Was. When Luke visits from Oxford, he and Sky finally meet one another in person and bond for the first time. "Farewell, Sarah Jane" Luke makes a further appearance in "Farewell, Sarah Jane" (2020), an epilogue for the series where years after the events of the main series, he has now come out as gay and is happily married and is now working with UNIT. He finds out whilst being in Geneva, that Sarah Jane has passed away and along with Clyde and Rani, he organises her funeral where everyone is celebrating her life. Planned character developments Had the series not been ended by Sladen's death, Davies had intended for Luke to be gay. References had been made to Luke's friend Sanjay, whom Davies intended would be introduced properly as Luke's boyfriend. Although this was a development suggested by the network (CBBC), Davies still ultimately chose to cut a line which hinted at this development in the Luke-centric two-parter The Nightmare Man. The line which is cut is from the scene in which Luke saying goodbye to Sarah Jane as he departs for university. Luke was selected by Davies because producers "wanted us to have a gay character on children's BBC. Just a normal gay character," and Luke fit this description. Dave Golder of SFX was critical of this reasoning, and felt that a character of non-alien origins or without special abilities, such as Clyde, would have emphasised normality better. By contrast, editors at Hypable felt that "in hindsight," a number of Luke's "socially awkward scenes" from earlier in the series "could be seen to have forecast Luke's sexual orientation, and they even inspired some fan fiction of that sort." The mini episode Farewell, Sarah Jane, published on the official Doctor Who YouTube channel confirmed Luke's sexuality as he says that he and Sanjay have been married for five years.
