About Shiva and her dragonosexuality, in the french version of the game it's clearly stated that she had sex with a dragon, to symbolize the union between men and dragons and the possibility of a peace in this neverending war ( Which the Ishgard writters apprently tried to hide ), Shiva's last word when you kill her could also be translated as "I wish I could fly with you my beloved" clearly stating that she was in love with that dragon.
