@katrina bc she was ready to sacrifice herself to save him and the country. And then he's like "aww that's so sweet but I'm willing to let everyone else die so my spoiled little sweetie gets a man 😌"
She's not pissed, it's more like "is that how everyone sees me? They think I care more about my looks and getting married than genocide? They think I'm that selfish? Even my brother?"
It's less 😡 and more 😨
Like she's a spoiled princess for sure, but she's still human. He assumed something very inhuman about her character, and that hurts.
