This was the only field report released after the episode. In 1893, Madame Vastra and Jenny Flint are given information concerning the Doctor by Clarence DeMarco, in return for a stay on his execution. They use soporific drugs to hold a conference call through time and space between themselves, Strax, River Song, and Clara, in a dream. Vastra repeats DeMarco's words: "The Doctor has a secret he will take to the grave, and it is discovered." During their conference, eyeless humanoids called Whisper Men kidnap Vastra and Strax and kill Jenny. The Great Intelligence tells Clara to tell the Doctor that his friends are "lost" unless he goes to Trenzalore. The Doctor and Clara travel to Trenzalore, the planet holding his future grave, to save his friends. The planet is covered with tombstones, the result of a great war, while a future version of the TARDIS (having deteriorated and grown to enormous size) stands above the graveyard. The duo are attacked by Whisper Men. An echo of River, still telepathically linked to Clara, helps direct the two to an escape route that leads to the giant TARDIS. Strax, Vastra, and Jenny (who is revived by Strax) are awakened by Whisper Men and meet the Great Intelligence. The Great Intelligence threatens to kill the Doctor's allies unless the Doctor says his name to unlock the TARDIS doors. The Doctor refuses, but as he speaks, River says the Doctor's name and unlocks the TARDIS. Inside, the Doctor reveals a pulsating column of light to be his time stream. The Great Intelligence enters it in order to undo the Doctor's past as revenge for all the defeats it has been dealt. The positive effects of the Doctor's travels begin to be nullified by the Intelligence's interference. Jenny and Strax both disappear. Clara remembers the Doctor telling her that she has helped the Doctor in other places in time and space. She enters the time stream to restore the Doctor's timeline. Echoes of Clara fall through space and time and appear in adventures of the Doctor's previous incarnations. The Doctor enters the column of light to save the original Clara, guiding her from a place where she sees several previous incarnations of the Doctor. Reunited, the two spot another figure in the shadows which Clara does not recognise. The Doctor explains the elderly figure is another past incarnation of himself, but what he did in the past was not in the Doctor's name.
