From Jenny Everywhere Wiki
In one reality, Callum Phillpott was baffled, just after finishing a Jenny Over-There story called Annals of the Jen: One Year of Jenny Over-There, to discover that the other half of a brief exchange between Jenny Over-There and John Watson in the story was reflected in one of the stories in the book. Even odder, that story explicitly featured the Man in Grey. (PROSE: Annals of the Jen: One Year of Jenny Over-There: The Birthday Toaster: Notes)
