Biography
In November 2010, the Shopkeeper who refused to state his age, told the Ealing Echo that there was an alien in his shop. When Sarah Jane Smith, Clyde Langer and Rani Chandra saw the paper, they arrived at The Shopkeeper's shop. He revealed that it was a ploy to get them here to send them through a time window to a different time period for each of them so they could find three special objects. Sarah Jane was sent to 1889, Clyde was sent to 7th June 1941 and Rani was sent to 19th May 1553. As he monitored their progress he became increasingly anxious, noting to his parrot "Captain" that if when the sand timer ran out they would be trapped in the past forever. When the sands did expire, he tried to close the Time Window but it would not shut, if left open it would destroy the entire planet. He watched as Rani and Clyde obtained their objects and and returned. Sarah Jane returned empty handed however, but Angela Price, the granddaughter of Sarah Jane's companion in the past, gave her the final object and the Shopkeeper took it and with the others closed the Time window. He then bid farewell to the Bannerman Road gang saying Captain's work was done and he and the parrot teleported away. (SJA: Lost in Time)
