That's because she actually really cares for her. This way she can make herself look good and express her concern. She didn't say anything bad or against him anyway. She knows what she's doing.
I've had a bad feeling about the twin princess for a while now but even more so now. It's like she thinks she can be a better prince or something because she is always controlling him. And I'm pretty sure she just asked that the author be killed.
I know it's for the sake of the story but it felt really out of character for her to yell at the make knights and make them wait outside.
So far she has done things for the sake of the contract because she knows some things must be done. So why not let the knights follow their orders now? Plus...
