On 18 August 1951, the day of the Foxgrove village fête, Eddie and his wife drove off in their car, leaving their three-month-old baby Sarah Jane Smith behind in the street. Barbara and Eddie subsequently died when their car crashed into a tractor that had broken down in the road. Sarah Jane was subsequently reared by Eddie's sister, Lavinia.
Sarah Jane and her son Luke travelled from 2009 to meet Eddie and Barbara, and Sarah Jane decided to save them by deactivating their car so they would not be able to escape. However, while this change in and of itself had no major effect on the timeline, meddling with history near an unstable rift in time caused the rift to open, allowing the Trickster to fully materialise on Earth and suck it of its life.
After Sarah Jane returned to 1951 Foxgrove from the alternate timeline her parents' survival had created, Eddie and Barbara quickly worked out who Sarah Jane was and what they had to do. They decided to sacrifice themselves to save her world, restoring the original timeline. (TV: The Temptation of Sarah Jane Smith)
Behind the scenes
- Thanks to some good intra-series continuity planning, a well-placed photograph of Eddie Smith appeared in The Mark of the Berserker, the story prior to Temptation.
