And this week on The Unearned Hairdrills Can't Grant You Power - It turns out she wasn't the villainess, just a spoiled girl with an impractical hairstyle!:
Owen and the other knights can't help. Marielle sees them all as beneath her. Why this would prevent them dragging her back to her father if I ordered them to is a question I'm too busy psyching myself up to consider...
Marielle last week: "I just lied to the knights to get that Oafish Prince Edward out of the way."
Carolina this week: Surely she'll respect my authority as a member of the Imperial Family!
So, a nice try, but it was kinda doomed to fail no matter what Carolina said - Marielle's just too far up her own arse.
"By all rights, your entire family ought to answer for your daughter's wrongdoings."
Or, at the very least, for their inability to keep one noblewoman in a room...
"I'm but a servant, someone unworthy of such consideration from you."
I totally get why, emotionally, Marissa feels that she doesn't deserve such consideration (being bullied all your life will do that to you).
Even if, in reality, its generally considered a good idea to stick up for the people working for/under you.
