Echoes of Future Past was a Brief Encounter short story published in DWM 181. It tries to explain the First Doctor's involvement with the Hand of Omega as a gambit by the Seventh Doctor, creating an ontological paradox.
- Susan is mentioned.
- A TARDIS will assault the mind of anyone but its owner and his familiars. The Doctor's TARDIS did this to the Doctor when he stole it, resulting in memory loss.
- This story contradicts the comic story Time & Time Again, the novel Lungbarrow, and the audio The Beginning, all of which state that the Doctor took the Hand of Omega with him when he left Gallifrey.
