Sarah Jane Smith (Whatever Happened to Sarah Jane?)
From Tardis Wiki, the free Doctor Who reference
Sarah Jane Smith was a school friend of Andrea Yates who drowned after falling from Westport pier in 1964.
At the behest of Andrea, the Trickster altered the timeline to switch her place with Sarah Jane, so that Sarah died instead of her. Sarah's potential was confined to Limbo. (TV: Whatever Happened to Sarah Jane?)
