Twilight hasn’t been a dork since S01E02. That was basically the end of her arc.

• Getting excited over tableware placement
   
• Anything literally related to excessive use of books. Asking if there’s a book about being a princess. Looking for solutions in the Golden Oaks Library.
   
• Stressing over tests and learning, and applying that to Friendship. Literally the cornerstone oddity of her entire character. Like when she snapped in Lesson Zero, that’s adorkable in the most extreme.
   
• Articulating in unusually long and specific definitions. “There is no wrong way to fantasize”, scene a Changeling spoke praise about Starlight and Spike groaned, “Definitely a Twilight fantasy.”
   
• Believing her test to the Crystal Empire was a literal academic test.
   
• She built an entire boarding school to teach the concept of friendship.
   
   
  She’s not only a dork, she expresses every feasibly expanded definition of the word. Her EQG counterpart wears glasses and makes overused attempts to solve everything with math and science.
