Mabel and Dipper were both 12 when they visited Gravity Falls, Oregon. Then, they left when they were 13. Let's go see what happens when they both turn 14.
NOW PRESENTING: Mabel and Dipper's Teenage Years
"Happy Birthday to You, Happy Birthday to You..." everyone sung as they crowded the two twins. When they finished, Mabel wished on the 1 and Dipper wished on the 4.
"I'm glad I wasn't stuck in those other dimensions today, or I would miss you two turning 14!" Stanford exclaimed. Stanley nodded and smiled.
"Thanks guys!" Dipper said grinning. As Dipper and Mabel ate their pieces of cake, Candy and Grenda came over and sat next to the twins.
"So guys, are you ready for high school?" Candy asked. Dipper shrugged while Mabel had a excited look on her face. Mabel and Dipper heard that high school was terrible according to Wendy. Dipper knew he would probably only be friends with Mabel and her friends, but Mabel knew that she would be the most popular girl in school. Mabel had grew so much from her preteen years, but her personality never changed. Dipper had matured into a proper young adult, unlike other boys, which surprised his parents. Dipper had grown out of hats and caps and started to wear plaid. Mabel kept her sweaters but knitted for her and friends. Dipper started to wonder if Mabel would ever mature into a responsible adult later. Dipper knew that for know Mabel will remain, well, Mabel. Dipper still loved his sister still, no matter where or when. He wanted to go through thick and thin with her by his side. Mabel loved her nerdy brother as much as he loved her, so her and Dipper loved each other dearly. They thought nothing would change it, but they were wrong. They were very wrong.
