I feel like at this point, the game is stagnant until a) mc FINALLY gets with Abby (cause seriously, the game's been going on for too long without having legit progress with her sexual/romantic route, and b) the ex wife steps back into the scene to cause actual conflict. There is also the chance that Becca is mc's biological daughter, but even still, we need to have actual progression. I also agree with others that the dream sequences no longer add anything to the game and just feel like filler.
As for that, I had made a suggestion a while back that could happen before a scene with Abby:
A Dream of Jess. Frank never really got over her death, and she was an important person to him, as Abby, Becca, and Lilli currently are. Other than the girls portrayed in an angelic form that speaks to him and somewhat dispels his self-doubt. Possible topics of conversation:
Her amusement at Abby being such good friends with Shannon's daughters and that it drives Shannon crazy. Also amused that Frank has already had things with both of Shannon's daughters.
The thing with Abby: That she's not necessarily happy about it, but it's not his fault that it's come to this. And that she gives him her blessing for it.
Her death: That it's not his fault (only the bitch who knocked her down is to blame) and even though it's a tragedy what happened, the lives of others (Becca, Lilli, Mei as examples) were improved by it and who knows where they would be today otherwise.
That Frank needs to be strong for his girls, as times will come when the three of them will simply be overwhelmed.
Probably also something about the Beth situation and that Frank is a Disney princess, but without the wedding at the end. I wouldn't put it past the image he has of Jess to make a joke like that.
Would be a dream again, but could definitely advance Frank's character development.
