I personally find the new approach of this point better, the fact that *only* bullying leads to the escape from wollust is now quite unlikely. There must be something more going on to provoke Katie for going full balistic towards William, especially because the cat was already out of the bag and the quality time between Willian and Leia was more or less an open secret within the family. Dylan has even lied for William in this matter.
As I wrote in an earlier post, there has to be an "info/background story Bang" coming sooner or later. As reworked Willi and Leia are coming across, they were far from being saints, but could take one on the chin when needed. As Mortarion remarked correctly, Willi and Leia´s quality time together was more or less out of the bag. Dylan had even lied for them and in ch.2 we see Helen secretly spying on them to see what they do.Yea enough reworks for now.
But I have to say that WastedTalent got a point. MC and Leia seem very unlikeable in the reworked narrative for now, not to mention that MC in general seems like a stereotypical Chippendales pretty boy that is an asshole to boot. Could put people off from playing someone like that in the first place. Even if Ocean turns it around and supplies sufficient motivation it might already be too late at that point.
Do you believe the Twins would be so thrown by Kati spilling the details about it, that Willi fled Wollust and Leia contemplated it? Not really, I think. Whatever Kati did back then must have been big and devastating. Up to the beginning of the game the Twins and Kati never forgave each other for what she did. Whenever it is revealed what Kati did, I think it will also be something which will let reworked Kati loose a lot of current shine.
