Davenport

Davenport was a footman at the home of Lady Clemency Eddison in 1926. He had an affair with Lady Eddison's son, Roger Curbishley, which by the time of the arrival of the Tenth Doctor that December was clearly well developed, both sneaking away for secret rendezvouses. Davenport could mix drinks in Roger's favourite style. He was the first to realise Roger had been killed and expressed despair at this. Donna later expressed her sadness that because of the attitudes of the time, Davenport could not publicly mourn his lover's death.
