Goiky was attacked by a glitchy black liquid called "The Corruption". Everyone got corrupted by The Corruption. You were the only one who wasn't corrupted. But everyone still acted like their normal day selves to you. They didn't corrupt you. They just like you

Corrupted Ruby: So, Snowdrop. How's not being corrupted like us?

Corrupted Eggy: Y-y-yeah. It kinda sucks being like this..

Corrupted Firey: A-a-agr-gr-ee

Everyone basically had The Corruption on them, big white eyes, and they're mouths were kinda stretched
