Know what would have been interesting? If Arianna and Willow were twins. I mean, they already look so much alike. Arianna could still be the older sister, and the one with the expectations on her, but it would sort of hint at the original fairytale, in which Rapunzel gave birth to twins, which is very often a hereditary trait.
Having Arianna and Willow be twins could imply that Rapunzel eventually would, too.
Ariana was born into an aristocratic or noble family. When her parents plotted to kill the king and queen of Apollonia, they lost their land and were banished to a pig farm. Ariana later wed the oldest king known alive. Three days after their union, the man died of a heart attack but they managed to conceive their daughter before his death.
Thus, Ariana is the queen of an unknown neighboring kingdom and the mother of Luciana. She comes across as a sophisticated and enthusiastic woman who's also serious about her role as a royal. Behind closed doors, Ariana is wicked, pushy, vain, selfish, and strict. She has never loved anyone in her life, including her daughter and late husband, only viewing them as tools for gain. This is because Ariana believes status and wealth is the only thing that will guarantee a good life. As such, she's ungrateful for what she receives, complaining about how a massive room isn't big enough for her.
She's also quite judgmental towards those who are different. Ariana can be passive-aggressive, making snide comments towards someone while being well-mannered. She enjoys singing, dancing, and luxury. Ariana hates pigs, being dirty, or her daughter thinking instead of making herself look prettier.
More than anything, Ariana is vindictive and deceptive. She's holds a grudge against King Peter for ruining her life when she was a toddler, and plans to use his head for croquet. Due to this, she's patient when it comes to executing her plans. Ariana has no problem manipulating humans and animals alike. She doesn't care about what other people want, dominating others and using poison to achieve her goals.
The fact that "After a failed assassination attempt on the royal family, a young noble woman with her family was sent into exile, their lands and title taken away. She ran away and climbed the social ladder again by marrying into royalty, then killing her husband suffering from a heart condition. Once learning that the king who sent her family into exile had a son, she had a daughter her own, who she planned to use as a pawn by marrying her off to the king's son, then after the wedding getting her revenge by trying to execute the failed assassination again" is a plot in an animated Barbie movie is still the wildest thing ever.
You know, I see a few Unknighted Dream fics involving how Rapunzel's relationships with Cass and Eugene is seen by outside royalty, but I'd love to see one that's the reaction of her PARENTS to finding to their relationship. Like, after everything that's happened, how WOULD Fredric and Ariana react to Rapunzel bringing Cassandra into her relationship? Maybe even having her officially become her consort depending on the fic? It's interesting to think on.
if y'all haven't heard Love is for Peasants from Barbie as the Island Princess then i need y'all to just take a moment to listen to it. you'll thank me later.
