i have this headcanon where dave is a lost deity from the 3d realm and they were the one who created expunged but after they entered the 2d/real world they would stay there for a long time and forgot their original form and was stuck inside a human form for now, and expunged slowly got too much power and became the new god of the 3d realm and haunts dave despite not knowing dave is his creator
(i know this sounds cringe im sorry)
