After all the legal altercations involved in "Elementary, Dear Data", it turned out the whole affair had been a storm in a teacup. Jeri Taylor recalls "Apparently the Arthur Conan Doyle estate was irritated with Paramount because of "Young Sherlock Holmes" and they said no more, ever. Well, as in many walks of life it was never say never again; to my amazement they were willing to give us the characters for a very reasonable license fee."
	The "nested" universe stories that were the basis of the story even confused the writing staff. Ron Moore had to draw a huge diagram of the various universes as nestled boxes during the break sessions.
	The wallpaper design of Holmes' study in "Elementary, Dear Data" had been discontinued four years earlier and could not be exactly matched.
	Rick Sternbach on the gas planet collision sequence - "Our cry became 'This is not Nova', but we wanted to be as accurate with the gas exchange as possible. A lot of testing ensued, along with the discovery of the need for longer than usual sequences - twelve seconds as opposed to the typical four to five second shot."
