Here, have some Pines family headcanons I conjured from the ether of my mind *throws headcanons at your face*



-Back home, Dipper has a ton of books on the paranormal, UFO’s, ghosts etc. They are all basically full of shit, and after his summer experiencing the real thing, Dipper laughs when he reads them, and keeps them around just to amuse himself.

-Since Dipper and Mabel got so used to sharing a room in Gravity Falls, they frequently have sleepovers back home, each keeping a spare mattress under their beds to pull out for those occasions. They tend to have at least one a week, often more. Even as they get older, they keep this habit up.

-When one of the twins gets sick, the other takes care of them, such as putting on their favourite movies (even if it’s one that the caretaker twin personally hates), preparing hot soup, and just being a comforting presence in general. When both of them fall sick at the same time, Dipper and Mabel usually just cuddle up on the couch in a ball of collective human misery with a blanket wrapped around them.

-Mabel knits several sweaters for Dipper, all of which he wears gladly, especially during the winter. Every Christmas, she knits holiday sweaters for the whole family (this includes Stan and Ford, as they visit during the Christmas break), including matching ones for her and Dipper.

-The Pines twins gain something of a reputation for strangeness at school. People attempt to pick on Mabel. This does not end well for them when they are forced to deal with a vengeful Dipper. People attempt to pick on Dipper, but likewise, this does not end well for them when Mabel makes their lives a living hell for weeks by employing every irritation tactic she knows (she can be very stealthy with it during class). One time Dipper comes home with a black eye. Mabel confronts his attackers the next day and ends up breaking his nose. It doesn’t take long for people to realise not to mess with either of the Pines twins.

-Mabel and Dipper decorate the Christmas tree together every year. Their differences tend to collide when Dipper’s parts of the tree are neat and organised and tend to use one or two matching colours, while Mabel’s parts of the tree end up as complete chaos with flashing lights and bizarre decorations strewn about everywhere.

-Dipper and Mabel still investigate the paranormal activity in their local area. Naturally, there isn’t all that much, but they still manage to find it with the skills they picked up in Gravity Falls.

-Stan and Ford both talk to themselves a lot in private. Thirty years spent living alone at the Shack was lonely for Stan, so he’d talk to himself to feel less isolated. This is how he picked up the habit of singing about whatever he happens to be doing at the time. Ford spent a lot of time alone during his interdimensional travels, so he would talk to himself just to hear a human voice.

-Ford keeps a lot of habits from his portal days (including the aforementioned talking to himself habit). The belt he wears around his sweater once carried a weapon, and it is now simply a source of comfort for him as it makes him feel more secure. He frequently checks every corner of his room for anything that might be hiding in it (he had to deal with a lot of ambush predators before he returned).

-The twins love singing together, and often enter the school talent show as a duo.

-During their college days, Stanford and Fiddleford bickered over who got to use the nickname Ford, as they both liked it

-Dipper loves rain

-Dipper publishes a shit-ton of books over the course of his life, both fiction and nonfiction. His fiction books tend to be sci-fi, fantasy, mystery, conspiracy types of things, his usual jams (He publishes a series of six books autobiographically based on his and Mabel’s various summers spent in Gravity Falls, about a pair of twins named Alex and Ariel). His nonfiction books tend to be about a few different subjects. One subject is how to distinguish real supernatural phenomena from the false, another is where and how to find the supernatural, and yet another is simply to compile artistic photography he and Mabel have taken over the years (they co-author these books).

-Mabel, though she doesn’t write as much as Dipper, also becomes a published author. She is known for her romance novels (one of which is about a girl meeting a Merman), as well as her children’s books, which she illustrates herself. She publishes a few humorous life advice books, named “Mabel’s Guide to Life”, which are widely acclaimed both for their excellent advice, and their quality humour.

-Dipper and Mabel both have the full collection of one another’s books

-At some point in their twenties, Dipper and Mabel go traveling all around the world together

-Dipper starts his supernatural show, though it is not purely based on ghosts as he pictured when he was twelve. It covers a variety of supernatural phenomena, taking on a half nature documentary, half mythbusters style. Dipper takes on a somewhat Steve Irwin-ish role. He goes to various places said to be supernaturally influenced and either proves or debunks the legends. Mabel frequently appears as a guest, and she is a fan favourite, as the audience loves her personality and the dynamic between her and Dipper.

-Mabel takes her artistic pursuits to their broadest extents, partaking in fashion shows, art exhibitions and stage acting.

-As Mabel grows up, she donates her old sweaters to charity as she outgrows them, apart from a few of her favourites which she keeps for nostalgia’s sake.

-At some point, Dipper legally changes his name to Dipper, so that it’s no longer a nickname. He never used his legal name anyway, so why not just replace it with what has very much become his real name.

-In their teen years Dipper and Mabel start up a Game Grumps-esque lets play channel on youtube.
