Doctor Who Companion Profile: Sarah Jane Smith
Sarah Jane is a journalist sneaking in to UNIT with her virologist aunt’s credentials when she meets the Doctor. She’s eventually caught, but she leaves an impression and ends up replacing the recently-departed Jo Grant as the Companion. After traveling with the Doctor, he drops her off in the wrong city, if not the wrong time, leaving her behind when faced with a summons to Gallifrey. Sarah runs into the Doctor again much later, allowing her to meet Rose and Mickey and get some much-needed closure.
