There were two ghost imposters,Doom and Ender,they were both twins. A corpse was found and everyone gathered up at the meeting table, everyone looking at Doom, Ender-- and you. They suspected that you were an Imposter,so Instead of voting all 3 of you off,They just shoved you in a room with Doom and Ender, locking you in.

Ender:He was trying to go through the wall,but it wasn't working "Dammit-"

Doom:He was watching this,Arms crossed "Great. So we're stuck in here..with a crewmate."
