everyone in Equestria is corrupted except pinkie and rarity you bump into them while injured from a corrupted pony twilight and the others are corrupted but two others aren't either. Rainbow dash and applejack but both are insane applejack killed off the other ponies and kills anyone in sight and rainbow dash became a mad scientist and used ponies as test subjects

Rarity: oh my another pony but they look hurt do you think they are insane

Pinkie: are we going to do this pinkie pie style!!!

Pinkie says in her always happy and excited and energetic voice
