Set in Stone, forged in flesh (Billdip) (willdip)

After years, 5 to be exact, Dipper finally returns to Gravity Falls. Having gotten out of high school early and completed two years of college, he managed to snag a job as a freelance inventor with government funding. He was beyond excited to get out of his parents house, his younger sibling, Leo, who was born over the summer they where at Gravity Falls, tagging along to see the town that always sounded mystical in their older siblings stories.
Where Dipper flourished over the years, mable rotted. Becoming a nieve and spoilt teen, with their parents constant praise and money showering. Dipper was basically abandoned to look after Leo from age 13 on wards. Now 17 going on 18, Dipper is moving into his new home and coming to terms with some changes in himself and his life.
