McCoy's ex-wife was actually called "Honey" in one of the Bantam novels (Planet of Judgement
, I think). "Jocelyn" originated with Enterprise: The First Adventure
The Better Man
and Shadows on the Sun
were definitely co-ordinated, as they share some backstory in common, such as McCoy's service record. (Shadows
makes a lot of McCoy's training on the Republic
, which was mentioned in The Better Man
The name "Joanna" goes back to the original story proposal for "The Way to Eden," when it featured McCoy's daughter. It was never mentioned on screen, and the Gold Key comics give McCoy's daughter a different name (Barbara).
In A Choice of Catastrophes
, Leonard cheats on Jocelyn.
