This is how A mesmerized school goes in My Little Pony: Equestria Girls: Rainbow Rocks.
[We see the girls and Human Flash Sentry in the hallway]
Flash Sentry (EG): That guy is definately in possession of some sort of dark magic. How else could you explain what happened back there?
Rainbow Dash (EG): I don't know.
Pinkie Pie (EG): It's like he wants to destroy someone he has a hatred with.
Rarity (EG): But who does he want to destroy?
Applejack (EG): Who knows?
Fluttershy (EG): It's like he has the same abilities Twilight has.
