Synopsis: In fifth-century Britain, the Doctor searches for some horse chestnuts with which to compete in an upcoming solitaire conkers tournament. A young Saxon leads him to a field littered with chestnuts.
Upon collecting a sufficient number of chestnuts, he returns to the TARDIS--only to discover that his young guide has been taken by Vikings. As a distraction to facilitate recovering the boy, he sets the Viking ships on fire. Simultaneously, he hits the Viking guarding his new friend on the head with one of the chestnuts, freeing the wide-eyed young boy. The Doctor departs, completely oblivious to the fact that his young friend will now introduce the game of conkers to the posterity of history.
Notes: This story was originally intended for publication in The Incredible Hulk Presents, but that title was cancelled before it could be published.
Synopsis: The Doctor goes back to prehistoric Earth, where he had left Ace. Since being left there, Ace has discovered that an alien race is trying to conquer Earth at this early stage in its development, ostensibly because it'll be easier now than after humans arrive on the scene. To effect their colonization, though, the aliens have employed slave labor. Ace uses a herd of dinosaur to free the slaves and effectively end the colonization before popping back into the TARDIS and disappearing with the Doctor.
Notes: Illustrated text story that explains why Ace was absent in the previous few years of Seventh Doctor comic stories.
