Behind the scenes
There is a similarity between the Ninth Doctor and this incarnation of the Doctor, however such a similarity is entirely coincidental, as author Daniel O'Mahony worked on this story with no information that a new incarnation of the Doctor would be introduced just months after the publication of his novella.
