In 1951, Eddie and Barbara Smith, companion Sarah Jane Smith's parents, were killed in a car accident after attending the Foxgrove Village Fête. Luke Smith called this a fixed point in time. The Trickster, in an attempt to gain a physical presence on Earth, opened a time fissure between then and Ealing, 2009, and tempted Sarah Jane into entering it.
