Helen (Adrift)
From Tardis Wiki, the free Doctor Who reference
Helen was a female human who lived in Cardiff in 2009, where she worked for Torchwood Three as a specially trained doctor at a hospital on Flat Holm for those thrown through the rift and then returned. She was a generally nice person and had formed a flirtatious relationship with Jack Harkness, her employer. When Gwen first came to the island, Helen showed Gwen to the room that Jonah Bevan was staying in. (TV: Adrift)
