I cried when Melanie died, she was such a shining example of a true christian in GWTW.
Scarlett was irish catholic.
Mammy was one of my favourite characters. When Scarlett went back to Tara, not only did she get her strength from the red earth, but also comfort in the arms of her mammy, who would often scold her when she was doing things wrong. I can imagine she would receive counsel there and wisdom.
the most hrrobly shocking thing in the movie was when Scarlett fell down the stair and lost her baby. In the book, she had three children to each of her husbands but they were cut out of the film.
if she had turned to God I can imagine she made true her promise and looked after Wade.
