What I still don't get from the whole book is why Suzanne Collins had to kill Finnick Odair. I think it's unnecessary cruel - not to the fans (I went to check any explanations online - omg, what a crazy squeaking of teenage girls around the death!), but to Annie Cresta.
He was the only person, at least the way it is described in the book, who could comfort and reassure the unstable girl, he was keeping her from disintegrating. I'm not buying into the quasi happy-end with her having his son. I don't see how a mentally ill person who loses the light of her life can be kept together by this.
