Bleeding Cool have spotted an additional hint in the latest hunt for the Hurtoctor evidence, that happens to date back a whole month to Comic Con.
Paul Cornell's final upcoming Doctor Who comic book story The Girl Who Loved Doctor Who had a couple of teaser pages released. In them, there is a clear shot of Matt Smith's Doctor looking at a picture of all his faces in the TARDIS. Between 8 and 9? A silhouette. This further adds to the previous pages from the IDW range that help hint at the fact. You can see the pages below.
The Girl Who Loved Doctor Who will be out Christmas Week, just before Matt's final episode airs.
