Claire (End of the Road)
From Tardis Wiki, the free Doctor Who reference
Claire was a prostitute hired by Jilly Kitzinger as per Oswald Danes' request in 2011. He asked for the prostitute to be of legal age as he claimed he was leading a new life. When Claire arrived, Oswald asked her to dinner. She refused, saying that he was still, in her eyes, outside her profession, a monster. She stormed out, but not before letting slip that he would soon become a "Category Zero." (TV: End of the Road)
