From what i generally understood from reading the devs comments on Boosty and playing the game i can make a conclusion that - Terransite's path completely excludes the involvement of other Denvers family members in his storyline.
So, if Wanda gave herself to Terrance, then neither Faye, neither Lois, neither Nicole, neither Gene will not appear as Wanda's love interest in this walkthrough and thanks to the devs for this because otherwise the volume of crap that can be poured onto this game will be equal to the size of a small mountain.
However, i personaly don't exclude the possibility that devs have a possible scenario in which Terrance invites some of his "friends" into his games with Wanda and does something like a threesome. Optional ofcourse.
Also, in other words, devs writed about a possible scenario in which Wanda/Faye/Nicole could have a romantic relationship with consequences
in a single playthrough.
Based on this we can conclude that following Gene's path we could theoretically also have a relationship with Lois in a single playthrough especially if Gene accidentally grabbed her breast in Lois's room and she given him a goodnight kiss after. Perhaps Gene will become closer to Lois after she will have a big quarrel with mom.
Janet also likely excludes all members of the Denvers family from her plot as she already will not include Faye and Gene 100%. That's one of the reasons why she kinda reminds me a softer, feminine version of Terransite.
