I hate that she talks back to everyone but becomes silent when the prince is harrasing her

What can she do? She's been conditioned by him very deep so it's been wired in her to follow and obey him. She always admire him and for her, he's the only savioir she has since everybody else abandoned or ridicule her, so it's hard to get away right away and have change of mindset.. But she's trying to change, you can see that.
