I don't think you can really see a change here, but rather a continuous step in Dylan's approach. He just uses his situation, similar to how Sam uses his talent to score points with Sophia. It is easy to see that Dylan is very methodical in his approach and it probably won't be the last step in his master plan. BTW, with Ellie, Dylan use a different starting point. Here, he plays more the role of a supporter (not only in IT matters, but also in the matter of relationship counseling) and thus scores points. I at least like these stories much more than the Aiden path, which unfortunately comes across as too bland due to Aiden's lack of credibility as a villain.
I don't see the path of Vicky/Nat/Alyssa as teaching, but as classic corruption. All lesbian path (except maybe Ellie) in AWAM are going this way.
How Liam path goes on is a mystery to me, because the good wife path does not interest me and L&P already said that Liam will not cheat on Sophia. The only way I think is partner swap events, which, however, will still lie very far in the future, if the game ever reach this point.
