Mathieu Vivier

Methieu was a man who came from Belgium and helped Martha Jones during The Year That Never Was.

He first met her in a town that was being attacked by the Master's new government and took her to a refugee camp where she was taken to safety. He then told Martha about Brigadier Erik Calvin an ex-UNIT officer and the son of Alistair Gordon Lethbridge-Stewart. (NSA: The Story of Martha)
