sorry but this is not what DPC says in the update
he says that Bella's route is almost perfect, but that by playing it he thought it was missing something, now this something he's going to add, to a route that he thought was practically perfect, is going to be by necessity something minor, nothing that's going to change the tide. a few renders and some secondary animations. or do you think he wants to add a sex scene or major plot steps?
and at the same time the big free roam, almost certainly of the halloween party, which if not half the chapter probably took half the production time, is not an issue of the branching of the different routes (except marginally, otherwise every free roam in the second season is)
then for goodness sake, we have to wait and we will wait, but whether it was worth it we will know when we see the chapter, and it is not that the longer we wait the more satisfied we will be, it has never worked that way
you will see the glory when that something missing from Bella's route is a nice lawn to mow, after painting the fence and making pancakes
