You can thank Paramount for that one.
Paramount gutted several key threads out of the book, including an entire sequence where Calhoun and Shelby got into a practical joke war.
In book six, while Shelby was still in sickbay, she was slightly delirious from her head injury and was cheerfully saying, "Look at all the pretty bunnies! Bunnies everywhere!" (An in-joke reference to "Space Cases," by the way, but we won't go into it.) Calhoun subsequently created a fake computer-generated transmission which Shelby received on the bridge: Captain Binky and the crew of the U.S.S. Hutch, who had come to commend Shelby on her bravery and quick thinking under extraordinarily difficult circumstances, and present her with their highest honor: A 21-Bun salute.
It was all fun and a bit silly and Paramount hated it and ordered it cut, along with the rest of the joke war, and the true nature of the Prometheans.
But apparently one reference to Captain Binky slipped through.
It was also Paramount's determination to forbid any mention of Ensign Janos as being a Mugato. One of those slipped through, however, so now Janos is, in fact, a Mugato.
I am starting to get a bit alarmed, though, that after leaving us alone for the first four books (to great success with the fans) they're starting to choke-hold us.
