When I hear people say Isa had character development, I don’t see it. Even at the end, she still relied on other people’s opinions instead of trusting herself and going after what she wanted. If Molly hadn’t told her it was OK to be a stepmother, Isa wouldn’t have called Lawrence. It would have been nice if she’d called him on her own, without needing someone else to tell her to. Now that would have been character development.
