Character mistake: When Rarity sees her cat stuck in the tree, Rainbow Dash is sitting next to the cat, but when you see her, her cutie mark is not there. (00:17:15)
Continuity mistake: When Rarity levitates the stick to mark a spot where she detected the gems, she drops the stick right after a guard "threatens" her. Then, in the same scene, the stick has mysteriously disappeared.
Rainbow Dash: Oh you want to do this the hard way? we do this the hard way!
Trivia: Pinkie Pie didn't use the trombone to get rid of the parasites. That means she planned for the exact ending. Not unlikely, considering Pinky Sense.

Question: When Rainbow Dash and Fluttershy are floating with Twilight, Nightmare Moon, (In the form of smoke) floats right in Twilight's face, though she never notices it. Why is that?
Answer: The smoke floats a few feet away from Twilight and close to the camera so you might think that the smoke is right in her face.
