This post is based on an interesting and dramatic movie My Sister Is A Warlord Queen. In this you have described the story, characters and their decisions very beautifully. In particular Catherine hiding her true identity and then revealing it at the right moment proved to be a powerful turning point that changed the entire story. You bring out the themes of sisterhood, strength, sacrifice and self-respect in a good way. While Catherine's going to any lengths to protect her sister makes her character stronger and more impressive.
