Jamie McCrimmon (Land of Fiction)

When Zoe was transported back to the Land of Fiction after facing the Cybermen, she created a fictional version of an older Jamie McCrimmon as a friend and a mystery for the Doctor to solve.

Biography
This Jamie, who had believed himself to be real, discovered that he wasn't when a cut revealed that his blood was made of black ink, the lifeblood of the land. The fictional Jamie expressed upset about the Doctor never coming back to his companions and worry that the Doctor never checked on the real Jamie, who may have been left to a fate of being hanged by the Redcoats after the Battle of Culloden. At one point, he teamed up to heroically fight alongside Rob Roy MacGregor. Jamie refused rule over the land, which was given to Alice Liddell instead, as he was more of a fighter. Jamie told the Doctor to find the real Jamie if he ever found himself in the Scottish Highlands again. (BFA: Legend of the Cybermen)
