Julia Hardwick was a woman in her mid-20s living in 21st century England (possibly Hull). At some point in the early 21st century, she was exploring her attic when she encountered a package labelled "Grandma" which contained photographs and newspaper clippings from more than a century earlier. Among the photographs were images of a woman who looked exactly like Julia, and a message warning her of the Weeping Angels. One of the newspaper clippings, dated 28th June 1887 mentioned a woman by her same name who was claiming to be from the future.

Later, Julia encountered a gravestone in a cemetary for a Julia Baker: born 1987, died 1949.

Before she was able to solve this mystery, she came in contact with a Weeping Angel and was transported back in time to 1887, where she lived out her life as indicated in the clues she left behind for her future self, possibly in an attempt to change her destiny. She died in 1949 and her gravestone reads "A woman who spoke of impossible things." (WC: A Ghost Story for Christmas)

Unlike Kathy Nightingale, another victim of the Weeping Angels, who eventually adopted a birthdate in keeping with her life in the 1920s (give or take a few years) (DW: Blink), it would appear Hardwick/Baker never gave up insisting that she was from the future, as her grave stone states that she was born in 1987.

Behind the scenes

• Julia's last name comes from a newspaper clipping seen on screen.
• A Ghost Story for Christmas was a made-for-Internet "webisode" produced for the 2009 Doctor Who Adventure Calendar. Narrated by John Barrowman (in character as Jack Harkness), the mini-episode described the origin and abilities of the Weeping Angels, and included flashbacks to the episode DW: Blink in which the creatures first appeared.
• According to the newspaper clipping, Julia is said to be from Hull. It's unclear whether this is actually the case, or if this is just where she ended up in 1887. Coincidentally this is also where Kathy Nightingale ends up when she is transported back to 1920 in Blink.
• The webisode strongly implies that Julia somehow became her own grandmother, though the 3-minute short does not take the time to explore this further.
