A year after Weirdmageddon, Dipper and Mabel return to Gravity Falls expecting a "Victory Lap Summer" - one last season of silly mysteries, junk food, and half-legal tourist scams at the Mystery Shack. Reality, unfortunately, has other plans.
Bill Cipher is gone... but the idea of Bill isn't.
When strange, self-drawing triangles begin appearing in notebooks, screens, and reflections, the twins discover that Bill's erasure didn't delete him completely. It shattered him. Now weak, scattered fragments of his consciousness hitch rides on leylines, electronics, and even dreams, trying to rebuild themselves one tiny pattern at a time.
With Ford treating the shards like dangerous lab specimens and Stan insisting you can't put "triangle ghosts" on a tax form, Dipper and Mabel find themselves stuck in a new kind of war: not against a physical demon, but against a spreading pattern. Bill is no longer a single monster to punch - he's static in the wires, glitches in the TV, a meme trying to lodge itself in everyone's brain.
To fight back, the twins do something only they would think to do: they create their own symbol, a messy "Anti-Triangle" that stands for them, their friends, and the choice to stay weird and kind in the face of cosmic nonsense. As fragments of Bill seep into photos, music, and social trends, Dipper, Mabel, and the rest of Gravity Falls have to decide which patterns they'll follow... and which ones they'll break.
It's a season about recovery after the apocalypse, siblings growing up, found family, and what happens when the villain comes back not as a body, but as an idea that refuses to let go.
