I agree with all your comments. While they try to keep up their royal status and smiles in front of their citizens, even the Royal Sisters can have a moment to have a petty squabble over something like forgetting their wedding gifts for the soon-to-be newlyweds.
“Fine! Next time you’ll bring your present and I’ll bring mine.”
“NO! Because then you’ll do what you always do and go past the price limit we set because everyone just HAS to looooove the precious Sun Princess!”
From all of the writers involved with this show, I always got the feeling, that Larson wanted to have a daily life of the royals sisters episode, the most. Looks like he finally made a start. Lets hope for more!
