- Just the premise: your best friends out of nowhere treating you like the enemy. In particular for those who often miss social cues in real life and are horrified and confused when people suddenly taking deep offense at them for what to them is no apparent reason.
- The scene where Sunset discovers that she's been erased from her friends' memories is no slouch either. Echoey footage from the previous three movies play over the sound of low bass as Sunset is seamlessly erased from each of her friends' memories. Like her, the audience doesn't know how it's happening, or why.
- The climax, when Sunset gets her memories erased. Until then, the memory-wiping process was never shown to be a painful process, but in this scene, Sunset's memories are shown to be painfully torn out of her head, with Sunset screaming her friends' names in a clear amount of pain and anguish. Despite the animosity towards her, Wallflower is clearly disturbed by the whole thing. It gets even worse when completed, and she has forgotten ever being human. She's down on all fours, panic-stricken and calling out for her mentor to save her.
- The Japanese version of this scene is even worse. Sunset Shimmer is heard to be screaming in pain as she calls out to each of her friends.
