Lady Cassandra O'Brien. "dot delta seventeen", or simply Lady Cassandra, was a former human in the far future. Along with other rich and powerful people of the universe, Cassandra was on Platform One, a space station orbiting Earth in the year 5,000,000,000, set to witness the destruction of the planet by the expansion of the Sun. According to Cassandra, her father, a Texan, and her mother, who came from the Arctic Desert, were the last to be buried in Earth's soil. She was born a male on Earth and lived on the edge of the "Los Angeles Crevasse". Cassandra, who was probably an aristocrat, was very elitist and "looked down her nose" at the working-class Rose Tyler, who she considered "common". She showed extreme arrogance at times, claiming to be the last "pure human" and considered all others to be "mongrels" due to their intermingling with other species. She was also very devious, callous and selfish, being perfectly willing to let all residents of Platform 1 be burned to death by the sun just to make money. (TV: The End of the World)
Cassandra's greatest failing was undoubtedly her complete unwillingness to accept death, despite the fact that, according to Rose, it was better to die than live like her. The Tenth Doctor was appalled by her willingness to possess bodies just to prolong her own lifespan, as it robbed the people of their own lives. Only when she discovered that Chip's body was close to death did she finally accept that it was time to die.
