If we assume that the bedroom belongs to Wade and Cindy and that there's no additional new backgrounds to the four already shared (which I think is implied by Eva's comments), that would necessarily also mean that the game will skip Lena's trip back home. Cause if there's no background for it, there won't be any scenes either.
To me that seems a bit strange, considering it was used as a cliffhanger and we know it must be a very dramatic event for Lena and her family. And unlike other cliffhangers, like Ian and Cindy getting caught, we know the consequences of it will follow immediately; it will either be the first part of Lena's chapter 9 or won't be part of the playable story at all.
Logically that should also mean that the chapter starts with Ian's point of view (which of course could include phone calls with Lena or other ways to merge her trip into the story), and then change to Lena later when she's back. It also implies that the intention of the trip isn't to introduce new characters, like Lena's brother, or completely new storylines; rather that something about the trip or her mother's condition will affect her existing relationships and life conditions.
I'd say the financial aspect of it is still likely to play an important part in this, as she'll probably need to support her family to an even bigger extent. But it might also be a good opportunity to address Lena's lack of serious relationship options. She's likely to be in an emotionally fragile state coming back from visiting her parents, so who she decides to turn to for support seems more significant than previous "booty call to Ian, Robert or Mike" choices.
Who knows, maybe Eva will use that as an opportunity to give a new dimension to some of Lena's more superficial relationships, like Louise, Jeremy or Stan? Taking Louise as an example, it would be a good opportunity to let Lena choose between getting her mind off of things by putting Louise on a leash and order her to eat her out (the usual procedure), or instead simply ask her if they could sleep together and let Louise comfort her.
