Hame

Senator, previously Novice, Hame was a member of the Sisters of Plenitude on the planet New Earth.

New New York Hospital
In 5,000,000,023, Novice Hame was tending to the Face of Boe in Ward 26 of the New New York Hospital when, along with others of her religious order, she was arrested by the New New York Police Department as conspirators in secretly breeding "the Flesh", cloned humans infected with all known diseases to serve as research subjects.

Punishment and redemption
Subsequently, Hame was ordered to look after the Face of Boe as a punishment for the crimes she had committed as one of the Sisters of Plenitude. Hame, unlike her unfortunate sisterhood, promptly reformed herself. During this time, she grew fond of the Face of Boe and actively sought to redeem herself for her actions.

When the airborne Bliss virus killed the New Earth Senate and most of the planet's population, Hame was saved by the Face of Boe, who used his smoke to shield and protect her. She then aided the Face in sealing off the Undercity of New New York, saving those on the Motorway and in the streets.

When the Tenth Doctor returned to New Earth thirty years after his first visit and Hame's subsequent arrest, the Face of Boe sent Hame to find him. She found him deep in the Motorway whilst he was looking for Martha Jones. They teleported to the New New York Senate so the Doctor could help the Face of Boe free the motorists stuck in the undercity. Doing this, however, cost the Face of Boe his life. Hame was with him as he died, breaking down in tears as the Face drew his final breath. The Doctor was sure that Hame had actually reformed and told Martha Jones that the city will "have Novice Hame" to help them adjust to life in the overcity, assuming she would now have a larger role in the governance of New New York and/or the planet.

Four years after the Face of Boe's death, Hame was still rebuilding the once-ruined city when the Cybermen and Judoon invaded New Earth and began upgrading the population. Allied with Thomas Kincade Brannigan, Hame summoned the Doctor and Martha back to New New York, and assisted them in defeating the two invading armies. (COMIC: In-Flight Entertainment)
