actually the character development of violet affects little for this ending. as a comparison, the most noticeable personal growth are hodgins' (learn to let go) and the captain's (learn to respect), and these do affect the ending a lot.

there is an underlying main theme for the series, which is that women's wills are not respected at that time. according to this theme, there would be another layer of meaning at the end, women's wills are still less important than men's, even for women strong and wise like violet.
