FLAY ALLSTER SPOILER!

Flay begins as one of the Heliopolis civilians trapped aboard the Archangel, sheltered enough that the war feels distant until her father is killed in front of her. Her grief turns quickly into hatred of Coordinators, and Kira becomes the easiest person nearby to blame, need and manipulate all at once. Flay deliberately uses Kira's feelings for her to keep him fighting, telling herself that sending a Coordinator to kill other Coordinators is a kind of revenge. It is ugly, and Gundam SEED knows it is ugly. What makes Flay more than a simple villain is that the series lets the consequences catch up with her. Separation from Kira gives her time to understand what she did and what he meant to her. By the time she wants to change things, the war is no longer interested in giving anyone clean timing.
