Thanks for translating!
Okay, so all of this madness (literally it seems, as she is cackling about ruling over all by being a chef) stems from her having a major inferiority complex? She'd better get a proper punishment when this arc wraps... Again, not just for her general douchebaggery, but she seems to think she can make puppets of the royal family and rule because she is palace chef...
Also major props to Mom, she continues to be cool.
And lastly, Katie... Just... Wow. If she was somehow dense enough to not get that her employer is a villain, then her stating aloud her intention to usurp power from the royal family... Come on now! She better not come out of this acting like it was the good old days and nothing happened.
I doubt she will die or see prison time, but her guild and career should be over, and she should be completely devastated by her own guilt and shame if nothing else.
