Taking a break from writing that Meat Cute with Henry fic y’all have asked for. ;)
I see Acacia as being the leader of the three (she’s not only the oldest, she is the Pole Star after all) and the one most like Mabel. I don’t want to say she is more ‘normal’ than her mother, but her flights of fancy are a little more restrained. However, she is the most outdoorsiest of the triplets and often goes on hikes in the forest with her mom (and handy demon uncle when Mabel is busy and she’s still too little to go on her own). She’s very creative, but her talents run more towards painting and drawing (and is good enough at it to make a career out of painting when she is grown). Acacia can also be very headstrong and stubborn, and occasionally her siblings need to talk her out of doing something completely idiotic. (or are talked into joining her. Acacia can be persuasive).
Hank is like both his father Henry, and also his cousin Wendy, in that he is a remarkably relaxed dude. Even as a baby, noises that would wake his sisters he would sleep through, loud explosions that rocked the house he would ignore, vacuum cleaners didn’t frighten him, and so on. Unlike Henry, who gets nervous in large social gatherings, Hank is very gregarious (like Mabel) and has no problem going up to complete strangers and twenty minutes later he knows their life story what? (If you are familiar with Discworld, think Carrot Ironfoundersson levels of knowing people). He is taller than his father at 6’9, and for the love of all that is holy, do not ask him if he plays basketball. He won’t do anything to you, Hank is just really sick of answering that question. He is, however, great with computer programming (Mabel and Henry aren’t sure where that came from but eh, Hank will always be able to fix their computer).
Willow is the quiet one, and takes after Dipper the most. She’s the loner triplet, for lack of a better term. It certainly is not that she is not close to Hank and Acacia because she is, because like Dipper and Mabel there are things only the three of them share, and they always grab on to each other. However, sometimes it feels as if Hank and Acacia are twins and she’s their younger sister. That doesn’t bother her though-she appreciates her time to herself . As a child, Willow had some health issues (that I totally haven’t thought of yet but will so stay tuned) and had to stay at home at times when Hank and Acacia were able to go out and run around, which meant she spent a lot of time bonding with Uncle Dipper. Of the three, Willow is the one that goes into the family business, and of the three, Willow is the one that gets into most trouble because she forgets sometimes that she doesn’t have to do things on her own, she has help.
(Dipper really shouldn’t have favorites, but Willow is a tiny bit his favorite)
