This is a fascinating tidbit about what may have pertained to Season 2 of the 1991 show.
Context: Innovation Comics was a short-lived independent comics outfit during the early '90s comics boom. They briefly had the rights to Dark Shadows, Lost in Space, A Nightmare on Elm Street and other properties, and produced gorgeous books with beautiful painted art. The quality of the writing varied wildly, but the LIS series in particular had some great, mature stories for such a goofy property, including an extended storyline written by Bill Mumy.
I read some of these books first as a kid and then a teenager. They can also be found to read online through 'alternative means.' The DS comics' rights very strictly pertained only to the 1991 series and were directly approved by Dan Curtis and co., though they were allowed to use Lara Parker's likeness for a new character in the first arc, in which Barnabas and Julia go to a town involved with the Salem witch trials. The DS comic ended abruptly with Innovation going bankrupt, amidst a new storyline focusing on ghosts and Sarah Collins, again with beautiful painted art.
The article above suggests Innovation - which had direct access to Dan Curtis - knew of some of the aborted plans for DS Season 2, including possibly a return for Lysette Anthony as the brunette Angelique-as-Cassandra. (I'd heard in the past that Michael T. Weiss would return as the werewolf Chris Jennings, but Peter Bradford recurring makes more sense.)
