Lad (Last of the Time Lords)

A lad who lived in London during the Year That Never Was was living in a house that Martha Jones visited. He talked to Martha while she was there. He later called out the Doctor's name on the street. When the Paradox machine was broken and the Year That Never Was ceased ot exist, the lad returned to his normal life. (TV: Last of the Time Lords)
