Jackie Tyler was a parallel universe counterpart of N-Space's Jackie Tyler, mother of Rose Tyler and wife of Pete Tyler. She was married to Pete Tyler and was the mother of Rob Tyler.
Jackie and Pete were members of an anti-government political group sceptical of the ban on post-Second World War technology. She was killed at a protest that was intended to be peaceful.
Before leaving Jackie's universe, Rose Tyler and Clive Finch visited her grave. (AUDIO: The Flood)
