Veena Brady
From Tardis Wiki, the free Doctor Who reference
Veena Brady was one of Donna Noble's friends.
Donna Noble mentioned to her mum that she was going to stay at Veena's house for a week. That was a lie. She was on her way to travel in time and space with the Tenth Doctor. (DW:Partners in Crime)
Sylvia Noble mentioned Veena when Donna Noble came to see them, saying, "I talked to Veena. She said you never came." (DW: The Sontaran Stratagem)
Alternate Timeline
In a universe in which Donna turned right instead of left, Veena was present when the Webstar appeared. She mistook the ship for a Christmas decoration. (DW: Turn Left)
