7 August

On 7 August 1941, Captain Jack Harkness, living through World War II for the second time, encountered an unnamed alien species in Cardiff. Returning to the Torchwood Three hub, the aliens broke through the doors and entered. A Commodore, apparently in charge of Torchwood, allowed them in and handed Jack a safe sent by Jack himself at either an earlier or later point in his life. Opening it, Jack witnessed the other version of himself getting instructions on New Year's Eve 2066 on the planet Zog. Following the instructions, Jack sang a song, which was intended to "switch them off". Instead, the song killed them, leaving nothing but piles of blood. (COMIC: Overture)
