Due to their curiosity about Susan Foreman's incredible knowledge of history and science, and her unique gaps in knowledge regarding present-day culture, such as forgetting that the United Kingdom had yet to adopt a decimal currency, along with her home address being recorded as "76 Totter's Lane", a junkyard, Ian Chesterton and Barbara Wright decided to drive to the address and wait for either Susan or her grandfather to arrive. (TV: "An Unearthly Child")

Alternate timelines

Ian and Barbara trail Susan home. (COMIC: Prologue: The First Doctor)

The same course of events naturally took place (COMIC: Prologue: The First Doctor) in an alternate timeline created when an exiled Rassilon allied with the Cyberiad to conquer all of history, (COMIC: Supremacy of the Cybermen) which resulted in the Cybermen capturing the First Doctor before (COMIC: Prologue: The First Doctor) what would be Ian and Barbara's first trip in the TARDIS. (TV: "An Unearthly Child", etc.) This timeline was ultimately aborted. (COMIC: Supremacy of the Cybermen)
