The TARDIS

 * The Doctor describes the TARDIS as "a box of cubes" with each cube shuffling around if the box is shaken.
 * There are apparently many console rooms in the TARDIS. (Possibly contradicting the "desktop theme" comment in DW: Time Crash, or perhaps a simple reference to there being auxiliary control rooms such as the one introduced in DW: The Masque of Mandragora.)
 * Some aspects of the interior remain as it looked in the classic series, including white rooms with roundels, a garden (DW: Logopolis), industrial-looking corridors (DW: The Invasion of Time), and a cathedral-like room (DW: Doctor Who TV movie). Of this last, the Doctor acknowledges that he hasn't been in that room for awhile.
 * In addition, Adric's room still exists within the TARDIS.

Other

 * Martha has recently married and is still with UNIT.

Timeline

 * Tesseract occurs soon after: IDW: Fugitive (possibly immediately after as Emily changes out of her 1920s dress in part 1), and at some point after the events of DW: Planet of the Dead as the Doctor references Lady Christina.
 * The reference to Jack's sonic blaster and the veiled reference to River Song indicates that the Doctor hasn't yet met her (at the time this story was published it was unknown when the Doctor first met River (from River's perspective).
