Piedmont will have absolutely no clue how to handle Post-Weirdmaggedon Dipper and Mabel.
The neighborhood kids play hide and seek and they’re hanging out on some random roof. You can’t beat them if you can’t reach them, suckas.
They’re outside every hour of the day. Literally. If you happen to be outside at two in the morning you might find them mid-magic hunt. Why not? Ford always said to take advantage of your insomnia for science.
Once some teenagers performing some weird Halloween hazing the Pines kids absolutely wrecked them. They literally have no chill.
For that matter, if you look Mabel in the eye, rumors say, you immediately have to play a game of cards with her. Never take pocket change anywhere near their street.
The pig goes with them. That’s final.
They say Dipper Pines has a six pack. They say he’s shredded. They saw he’s got a scar across the belly from fighting off a pack of wolves with his fists.
All the doors in the world are open if you know how to pick locks… Not that they’re saying they can. That’s implementing themselves in multiple unsolved crimes, and that would be stupid.
Feel free to add your own!
Mabel starts leaving handmade jewelry around their school, their neighborhood, the local grocery store. People who know her are afraid to touch them but strangers pick up these little wire and yarn doodads and find themselves having some very good luck.
There’s a rumor that that kid who always falls asleep in class couldn’t sleep at night because a ghost was haunting him. One night they find out that Dipper got in trouble for breaking into his house in the dead of night. That kid stops falling asleep in class.
On all their homework and tests, they leave behind red ink eyes crossed out with an X. One of Mabel’s classmates asked her why and she looked up front, at their Trigonometry teacher and said, just in case.
Dipper listens to a death metal band called Robbie V and the Tombstones. No one can find their songs anywhere, but if you ask he’s happy to lend you his CDs.
Mabel remembers everything, about everyone. She’s the only one who remembers the birthdays of the kids with no friends and she shares happy memories when her peers are upset about a grade or family stuff. She writes down little details in a pink glittery notebook, so that no one will ever forget.
Dipper and a group of his classmates went on a field trip in the woods. When Dipper disappeared for several hours, the teachers panicked, but he appeared at their bus a few hours later, having collected all the data he needed for his bio lab and toting a jar filled with multicolored moths. He’s banged up, but he doesn’t seem to notice. When someone asks where he got them, he says “Mothman” and doesn’t answer any more questions.
Mabel makes a tidy profit off of Mabel Juice during final exam season. Half their graduating class will swear by it all through high school even if it does taste terrible. (The arrest rate for stimulant drug use drops close to zero.)
These are amazing!

Even right after they return, when their teachers ask them to share what they did over summer vacation, the Pines twins (mysteriously in all of the same classes –no one wants to imply that someone changed the class registers, but someone probably changed the class registers) just smile and shake their heads and say “nothing interesting” and “we spent the summer with our great uncles.” Everyone is nonetheless absolutely certain that the aura around them has changed in some inexplicable way.
Dipper writes everything down in a blank field journal, and is never seen without it. There are entire chapters written in ciphers with no handy key available, and he sometimes switches ciphers midway through. No one has the courage to ask him if he’s actually writing anything; they’re afraid the answer will be no. They’re even more afraid the answer will be yes.
Mabel has a thriving pen-pal relationship to almost everyone they met in Gravity Falls. “Who are you writing to?” will get answered with often inane answers, such as “he was our mailman and probably a werewolf” or “the sheriff and his first officer; they’re in love.”
Mabel also receives eloquently written love letters that she never opens. At one point a pair of girls caught hold of one before it reached her, and read it, and were alarmed when they handed it over to her (resealed, of course) and she lit it on fire without even opening it. “They’re from Gideon,” Mabel says, as though that explains everything, smiling in a way that somehow doesn’t seem at all innocent.
They never agree to any request unless they’ve seen the other party has done their portion of the deal first. That’s a lesson you only ever have to learn once. Never trust words at face value.
Once, hanging out with friends on a clear autumn night, one of the girls pointed upward and said “Shooting star!” Mabel flinched visibly and would not explain why.
Mabel has a woven bracelet made of rainbow-like material that she never takes off. When asked about it, she says it’s unicorn hair. Dipper will sometimes muse that one of her teeth got chipped from that and their parents hadn’t been enthusiastic about the extra cost to their daughter’s orthodontic plan.
YES YES AND MORE YES
Now I’m just seeing Dipper and Mabel slipping in and out of ciphers without meaning to, wearing unicorn hair (Dipper probably has a anklet or something), chugging Mabel Juice like it tastes fine, drawing x-ed out eyes on their arms and such.
It’s not a Pines Twins headcanon after Gravity Falls unless it has that vaguely unsettling sense of ‘something is not quite right with them’. At least, that’s my personal take on it.
Their parents sometimes hear them speaking in the bathroom when there’s only one of them in there. When asked they shrug with a smile and say they’re just talking to their reflection. The parents never question why the other voice sounded nothing like their children’s.
Mabel is often found sending messages in bottles at the local river no matter what season. When asked she says she’s sending them to a penpal. Every so often she’s seen with new shell necklaces or reading letters written in Spanish. She never took Spanish.
The fandom is coming together to create this really cool after-series magical world for Dipper and Mabes and I am HYPE YA’LL These are some seriously good headcanons!
Their classmates spend a good portion of one summer following Mabel’s Instagram posts from a castle in Austria, totally casual with her arms slung around a baron and his girlfriend
Dipper’s classmates are confused by his hat switching styles every other year (it became a tradition for him and Wendy to switch at he end of each summer)
There’s a rumor that Dipper knows a special combo code for Fight Fighters at the local arcade but every time he’s there and someone asks he’ll just laugh it off and walk away
Sometimes a student will check a book out from the school or local library and it’s FULL of scribbled notes & ciphers
Somebody spent the time and effort to add a man named Quentin Trembley to the history textbooks in sparkly purple gel pen and the students always joke about having a question about him on the final
Any time one of them does something mildly rude or inconveniencing to the other the victim yells “I invoke GLOBNAR!” and mimics shooting a laser gun at the other
They get a physics class assignment to build a miniature bridge that can withstand a certain amount of weight, theirs ends up strong enough for the teacher to use it as a replacing desk leg. The whole bridge is faintly pink and glows slightly when the lights are turned off, and when asked what their secret is, the simply say “it’s all about the glue you use”
Mabel goes mini golfing with some friends. She insists on checking all the little tunnels you hit the balls through before she makes any swings, but gets repeated hole in ones. Her friends start checking as well, just to see if her luck will rub off, but Mabel claims it’s just skill.
Dipper treats photocopy machines like most people treat ovens: perfectly safe as long as you are careful and don’t touch the operational part of the device.
At one point in a thrift store, Mabel freaks out and demands to leave, but her friends don’t understand why she’s so upset over some old BK kids club merchandise.
Dipper joins a DD&MD campaign and complains when his Gnome Bard can’t team up with people to shatter undead skulls by singing or form a giant voltron Gnome. He eventually becomes the DM and wows his players with incredibly creative homebrew monsters, but refuses to include Probabilitor in any of his adventures.
Eventually, The Pines Twins become known as the Mystery Twins in Piedmont too
Some years they come back with a new scar somewhere
It’s said that they managed to befriend some of the wild animals in the nearby woods
One of Dipper’s old bullies run into him and tries to tease them again. He’s never seen in the same place as the Pines ever again
If you listen closely to the twins when they’re chatting you can hear mentions of something called a “multi-bear” before they switch to speaking in cipher because somehow they noticed you eavesdropping
Most of the deaf and mute students in school know the Pines because they know Morse code and sign language
Any bully that the Pines See are sick the next day
Occasionally, when you chat with the Pines about the supernatural, they tend to randomly correct a few things. For example, pure elves are actually pretty ugly. When you ask how they’re so sure, they just share a knowing look and say “Our Grunkle told us”
The Pines Twins are way too smart.(Ford could tutor them both, if only to keep them in the same grade) But for some reason they never want to skip grades. When asked, they simply say “Don’t want to grow up too fast”
