This might be a weird question, but does Priscilla have a favorite family member? Does she have one she doesn't get along with?

Oh, Priscilla absolutely does have a favourite family member. And that, in fact, is her Uncle Charles. And everyone in the Kimbleton family knows Charles is Priscilla's favourite Uncle, ha.
Charles Kimbleton actually goes through some character development with Priscilla however, and thier mutual favoritism didn’t happen overnight.
As you know, Priscilla’s Mother, Josephine Kimbleton, eloped with Priscilla’s Father, Dr. Raleigh Duncan, while still in an arranged engagement to a super wealthy super good-looking nobleman.
Charles was shocked over his sister Josephine's elopement and causing such scandal, and while he didn't display any open disdain towards the 'eloped offspring', he was just conveniently offshore overseas all the time. That was until Charles was back home in London (After Josephine’s & Raleigh’s disappearance) and Uncle Thomas forced him to babysit Pris while everyone else was out of town.
And it was then that Pris slowly melted his heart. Then again, I mean, how can you not adore Pris?? But especially to him what he found unlike his other nieces and nephews - Pris had a longing for the outdoors, a fascination for birds and nature, science, and wanted to hear Charlie's stories 24/7. Charlie soon learned whatever 'wrongdoing' her parents had done, Pris was completely innocent -- and boy did he then try to make up for any of his mistakes. To the point that he became to closest to being an actual father figure to her (moreso than Uncle Thomas more often than not). Charles became the real mentor to tell Priscilla to follow her dreams, weigh out both her heart and her mind in making decisions, and to enjoy life’s adventures.
It’s so tragic that canonically he too ‘disappears’ for the next 10 years shortly before Priscilla’s relationship with Edmund goes south / Priscilla breaks off her engagement (the time when she needed her Uncle Charles most). *quietly weeps*
Fortunately, that’s remedied in Priscilla’s verse v: Stephanoxis Ialandi which is basically the ‘what if?’ verse of instead of being raised by Uncle Thomas, it was Uncle Charles! Also, Charles makes a more notable appearance in Priscilla’s Wild West ‘Western Horizons’ verse, so that makes me happy too.
(I’d also like to add Priscilla’s second favourite family member is probably her cousin Emmett Kimbleton. He’s majorly underdeveloped, but I know he and Priscilla were childhood friends and Emmett was always kind to her throughout her times of difficulty, as well as was the only one who had a rotten feeling about Edmund before anyone else even considered it.)
(Her third favourite are tied with her Uncle Thomas Kimbleton and Grandma Cecelia Kimbleton!)
As for the family member, she doesn’t get along with, that would probably be her Uncle Henry Kimbleton (and his children / Priscilla’s cousins). Henry is Grandpa Philip & Grandma Cecelia's oldest son. Dignified nobleman, very respected in high society. Left England to marry his wife Helene to live in southern France along the Riviera. He's the most 'to the book' of social customs, and demanding to keep the Kimbleton name as prestigious as possible (since he's carrying his father Philip's legacy the most). His un-favouritism to Priscilla, is, well, to put it bluntly, if you asked him uncensored he would tell you that she's a bastard child. (which is absolutely not true!!)Henry had the most indignation against his sister Josephine for breaking off her perfectly good arranged engagement to that super-rich nobleman and elope with some upstart doctor Raleigh. And clearly, that resentment passed down to Josephine’s only child Priscilla.
Priscilla doesn’t want to not like her Uncle Henry, she just can’t help it because he doesn’t even give her a chance to show she’s no less a dignified Kimbleton like the rest of her family. (And, you guessed it, they basically cut off all contact entirely after Priscilla breaks up with Edmund.)
And while Henry’s wife Helene mostly stayed out of it, Henry’s stigma also unfortunately also caused some awkwardness between Priscilla and her cousins, his three children: Henry Jr., Winifred, and Cynthia. Nothing unfriendly, per se, and more indifferent and preoccupied in their own lives. Though I do know that Cynthia (who was the same age as Priscilla) always claimed to be the prettier one.
