Dipper and Mabel at Seventeen Headcanons

- After turning 17, Dipper and Mabel receive a special gift from their parents, which turns out to be their Dad’s old car. Though the twins are excited, their parents inform them of the condition that they must share the vehicle. Dipper and Mabel decide to make a compromise with sharing the car by setting up a schedule of who gets to drive and when as well as contacting each other in case one of them needs to be picked up. They stick to their agreement and conflicts over the car are super rare (with the exception choosing bumper stickers and interior design). The streets of Piedmont are no longer safe once the Mystery Twins are behind the wheel of their own car.

- Ever since their second grade picture day, the twins up their yearbook photo game with each passing grade. The typical picture includes looking at their fellow sibling, posing side by side, and even dressing up in ridiculous costumes. When picture day for their senior yearbook comes around, Dipper and Mabel decide to share one last laugh. Sure they dress up in formal attire for the occasion, but they dedicate their senior quotes to Grunkle Stan.

Mabel Pines: My Ex-Wife still misses me…

Mason ‘Dipper’ Pines: …BUT HER AIM IS GETTING BETTER!!!

- Mabel and Dipper initially freak out during college application time, but they seek assistance through their guidance counselor. With the twins motivating each other, as well as help from the school, they manage to send in all of their applications before Thanksgiving. Once the Pines residence start receiving an abundance of large and heavy envelopes in the mailbox, Dipper and Mabel are ecstatic to learn that they got accepted into college. Mabel is especially overjoyed, having previously doubted her academic knowledge but worked hard to get good grades anyhow. Mabel decides to attend San Francisco State University with a high interest in its art program. Dipper goes to University of California at Los Angeles to work for his degree photography and media production like he always dreamed of.

- Dipper being an asset in the school’s marching band; He’s first chair tuba player as well as the section leader of the low-brass section. Dipper has embraced his nerdiness since he was thirteen, and he displays a lot of confidence in his musicianship and performance during a half-time show on the football field. His tenacity, in turn, inspires his fellow bandmates, including the younger members.

- Mabel being the president of the art club and being a mama bear to all the younger students. She’s the go-to person for constructive feedback as well as assistance. If a student doubts their own artistic abilities, Mabel will sit down with that person and talk it out before encouraging the student to give it another shot. She is loving and supportive of everyone in the club because she believes in the potential each person has to create something beautiful to call their own.

-Dipper and Mabel being apart of the varsity track and field team. These two have been very athletic from a young age and all of their running around in Gravity Falls had paid off when they first joined track. All of their peers who have once doubted the twins’ athletic abilities eat their words once they see the two come out on top in their respective races. Dipper succeeds running long distance due to the physical endurance he built-up over the years, and owns the mile and two-mile races. Mabel, who likes to challenge herself, is one of the school’s top hurdlers and she dominates the competition.

- Prom season kicks in and Mabel couldn’t be more excited. She makes her own dress and works tirelessly on her creation. Once the dress is complete, Mabel is pleased with her handiwork and she goes to prom wearing a pink ball gown adorned with rhinestone jewels and matching opera gloves. Dipper pulls a Grunkle Stan/Grunkle Ford by wearing a white tux with a pink vest and tie. The twins go to the school event with a group of friends and they end up having a wonderful time.

- The entire Pines family and friends from Gravity Falls attend Dipper and Mabel’s graduation ceremony. Stan and Ford rent out a van, bringing along Wendy, Soos, Melody, Abuelita Ramirez, Fiddleford McGucket, Candy, Grenda, and Pacifica with them. Soos prints out giant poster of Dipper and Mabel and proudly holds it up, despite the annoyance of the people sitting behind. Stan is especially proud to see his niblings receive their high school diplomas and is happy that history didn’t repeat itself. Dipper and Mabel look over at the bleachers and immediately spot their family and friends who are excited to see them graduate. The twins are also happy to share this important achievement with their loved ones.
