Claim: Jackie Tyler is introduced in "Rose", she is attacked by shop window dummies and returns twelve months later from London.
Evidence: Jackie is introduced in "Rose" (2005) as the late-thirties single mother of the episode's eponymous character, Rose Tyler (Billie Piper). She is later attacked by shop window dummies but is saved when Rose and the Doctor destroy the alien consciousness able to control plastic. When Rose returns to London, twelve months have passed; in the intervening year Jackie had organised a missing person campaign to search for her daughter and accused Rose's boyfriend Mickey Smith (Noel Clarke) of murder.
