Because you're a family of Loners Dipper. You fell in love with a girl older than you and simped over her for the entire summer, Stan is a con artist who's chasing money in a desperate attempt to feel validated, Ford is an intellectual shut in who got fooled by an interdimensional demon god/possible incarnation of Loki, and Mable is a social butterfly who barely knows what boundaries are. Just take the dub and enjoy the orgy with Paz.
