Vanessa (Greeks Bearing Gifts)

Vanessa, previously known as Vincent, was a friend of Jack Harkness. According to Jack, Vanessa was once a "regular guy", who had a girlfriend and liked beer. Jack told Toshiko that Vincent disappeared for a couple of months, and upon return asked to be called Vanessa. "Since then I've always been a little nervous when a friend behaves out of character."

Behind the scenes
In the real world, Vanessa would likely consider herself transgender, and use feminine pronouns, in line with her gender identity. Yet the fact that writer Toby Whithouse has Jack use masculine pronouns in his anecdote suggests to some fans — especially when evaluated against some scenes in other Whithouse scripts — a level of transphobia in the writer's DWU output.
