Jeri Taylor and Rene Echevarria both regretted not being able to to develop all the plot lines, especially Hugh's, as much as they would have liked. This was partly due to the show not being finished until after hiatus.
	Rene Echevarria on 'Descent' - "Part I left many balls in the air and I had to catch them. We had a better idea of what this Part II was going to be like, but nothing turned out quite as simple as it had seemed."
	The first draft had Data shoot Lore in self defence as part of an extended phaser battle. However, Michael Piller wanted to avoid this, so opted for the disassembly.
	Ensign Taitt was meant to be Barclay in an early draft, but had to be dropped due to expense and availability.
	Director Alexander Singer on the location shooting in Descent II, which took place in the 100 degree Simi Valley - "Those Borg extras were dying! They had to wear black longjohns under those rubber suits!".
	Michael Burke (Goval) played the DS9 Cardassian Hogue in the second season episode "Profit and Loss".
