I feel like the change in personality was a bit like what TTG did with Larry in Season 1. No one liked Larry, so they chose to kill him in episode 2.
Similarly, people were supposed to feel sympathy for Rebecca when the time came (giving birth), so perhaps instead of gradually making Rebecca warm up to Clem, they made it instant to ensure that more people cared.
I was nice to nearly everyone as Clem. I couldn't play an edgy/sassy Clem for my life. Told her, "I'm a little girl." After the incident with Rebecca, I looked forward to other players' consequences about blackmailing her when there were none in E2 or E3. She just acts the same as if you hadn't said anything.
I haven't been thrilled with character dynamics either. I thought it was strange that Clementine could blackmail Alvin, sell him out even after he helps her and still have Alvin like her. Kid or not, that's strange.
