Can people in the fandom acknowledge that Mabel is also clearly a nerd, but she just doesn't show it? Like, one scene that always sticks with me is at the start of Dipper and Mabel versus the Future, they talk about high school. Mabel says that they learn about "You know what" and Dipper's reply is "Trigonometry!"
You would think that the next reply to this would be Mabel calling Dipper a nerd or something, but she replies with the same level of enthusiasm. She says "Oh yeah baby."
Only nerds are excited to learn about fucking trigonometry. Mabel is a fucking nerd.
