Betty was a specialist working in the orthopedics office that used to be House's conference room in the Season 8 episode Transplant. She was portrayed by actress Michele Marsh.
When House tried to retrieve his whiteboard, Betty blocked his path, put on a strained smile, and told House that Dean Foreman had assured her that if House caused any problems, Foreman would make sure he was sent back to jail to serve out the rest of his sentence. House backed down.
