One thing you should always do before a plot that potentially involves serious harm to others: talk to the OP gang. The Clash of the Final Day was such a mess partly because Bees never communicated with anyone about his plot twist.
Anyways it's foiled so imma tell you the whole story
There's an entity called the showman (puppet showman) and he has an obsession over roleplay control and order. He aims to turn the whole gang into puppets to do the RPs easily. Nerdee is unfortunately posessed by him, which changed his personality completely, which is why NerDee is always so cruel and bloodthirsty. (He used to be a nice and laidback nerd) However, at some times NerDee fought back and stopped showman's control, hence the sudden random posts. I tried to create an entire arc on the showman attaching his strings onto members, culminating into a battle of the survivors against the showman and his army of puppets. The showman is killed by having his core, the strings producing hands slashed in 1000 pieces and scattered across space. Then I return to normal.
This lore takes inspiration from Deltarune. I made it up in a few hours.
