Played By: Zoë Wanamaker

Formally born male to a father from Texas and a mother originating from the Arctic Dessert, the Lady Cassandra O'brien.Δ17 (Dot Delta Seventeen) was a human originating from Earth many years in the far distant future. Over the years he had a sex change from male to female and had seven hundred and eight different medical procedures to preserve and alter her form until she took on the appearance of "a trampoline." As well as that she had been married at least five times in her life.

At some point she had been invited to a party being held for the Ambassador of Thrace, where it was the last time anyone told her that she had looked beautiful- starting her descent into her Platform One look.


"New Earth"

During Rose's investigation of the lower level of the New Earth Hospital, she follows Chip to a room at the far end of the corridor where a projector is playing an old recording of the Ambassador's party. After a moment Rose realises that the woman on the screen, who is talking animatedly to a group of guests.

Cassandra comments that she remembered that evening well.

As a final act of mercy to Cassandra, the Doctor and Rose took Chip (who was sharing a body with her) back to that night. He watches her mingling with a group about her travels to Egypt (commenting on it being "tiny"- in her eyes) and complaints about the "mosquitoes." He thanks the Doctor, who tells her to "go and not look back" while Rose wishes them both "good luck." 

Chip makes his way towards her younger self as she tells the laughing group not to quote her on an unknown topic, calling them "naughty people" and calling to them "A Bientot" as she leaves. She stops as Chip addresses her, but mistakes him for a waiter at the party and tells him that she is "fine." He tells her that "she is beautiful", which she shrugs off with a feigned air of politeness, calling him a "strange little thing" and thanking him. However she is both moved and flattered (almost to tears) when he reveals that he truly meant it. Her tone changes when she sees Chip collapse before her and she holds him close, begging the guests to help him and call "a medic." She tries to ask if he is alright, while another guest asks who he was. Cassandra tells her that she didn't know and that they had just met, She shouts for someone to help, comforting her future self and her own creation as they pass away in her arms. Till their last breath, she tells them that they "will be alright... you poor little thing."
