Scarlette

Scarlette was the owner of a brothel on Henrietta Street in the 18th century.

Biography
One of a group who had 'inherited' the knowedge of the mysterious Elementals following their destruction, Scarlette aided the Eighth Doctor in coordinating a defence against a new danger from outside the conscious universe, the two actually falling in love to a certain degree over the course of their time together.

Scarlette died shortly after her wedding to the Doctor, in a ceremony that was originally arranged simply to symbolically bind the Doctor to Earth and allow him to participate in its defence, but which, it was implied, developed a deeper meaning for both parties.

According to records, Scarlette faked her death after the crisis was over, recognising that the Doctor's feelings for her would keep him on Earth when he needed to continue travelling to other worlds that would require his help. (PROSE: The Adventuress of Henrietta Street)

Sabbath later referred to Scarlette as the only woman the Doctor ever got close to. (PROSE: Camera Obscura)
