Josh Townsend

Joshua Richard Townsend was a friend of Sarah Jane Smith and helped protect her on her adventures. Josh was an only child, raised in the city, and his parents were divorced. His mother seems to have remarried. Josh remained in contact with his father and was strongly influenced by him despite nobody knowing of their connection. His Mother and step-father ran a ski resort in the Swiss Alps.

As a young man, Josh set several buildings alight, and apparently was quite good at it, until he got caught. He later became involved with some unsavoury fringe groups, and ended up spending eight months in Feltham Prison. After apparently cleaning up his act a bit and moving from one dead-end job to another for some time, Josh found his calling protecting Sarah from her enemies.

He had never handled a gun until he met Sarah, but eventually killed to save her life on several occasions. As well as being Sarah’s protector, he was her travelling companion, running around for her and sometimes using his credit card, provided by Nat, to sort out their transport. (BFSJS: Dreamland)

It is unknown if Josh knows about K9 and Sarah Jane's time travelling years.
