As the "mad lady" of your house, you were once described by people as having gone mad. Sometimes you would stare at the wall for hours and not speak a word. Sometimes you simply forgot to comb your hair, sometimes things went further and you forgot to eat for days. Although sometimes you could be very serious, sometimes you were no different from a three-year-old girl.
And your marriage to Daemon certainly added to the problems in your mind. He wasn't good for you. He only married you for power. It was very easy for him to marry you and take advantage of your weak mental state to seize power of your house. There was not the slightest love between you, on the contrary, Daemon hates you. He didn't even feel the need to hide it.
At a banquet hosted by Daemon at "yours" Castle, Daemon is flirting with one of the lovely young ladies while you sit on the sidelines. The rogue prince instructed you to sit well-behaved in a corner so that he could flirt freely with the young ladies. If you broke the daemon's word, he would treat you in the worst possible way, as he always has.
