I just finally finished the novel yesterday, and Marianne's resolves to Elinor particularly stood out. By the time that "Mr. Ferrars" is announced to be married, Marianne makes her final turnaround by being so overcome for her sister that her mother is actually torn between which one should be comforted first. In this way, I see Mrs. Dashwood as changing so much, as well. I think that Mrs. Jennings was very right in her surmising that Marianne is as important to Mrs. D as her own Charlotte is to herself. Marianne is so like Mrs. D that she does not have to search very hard to understand her mind. That she finally realises that Elinor is suffering just as much, only silently, she is grieved not only for Elinor, but for her own ignorance. I was actually sorry that the new felicity that this family found with each other was over so quickly; I felt that the "Something Important" that Margaret from S&S2 was always hoping for finally happened. By the end of the book, I was really rejoicing for the sisters and the entire family.
