I've been re-reading historical accounts of Spring-heeled Jack from the 1830s onwards, and something's been bugging me. The inconsistencies in eyewitness accounts, the way he appears and disappears across London with impossible speed, the behaviour that doesn't match any human or animal pattern - what if that's not a creature or a person, but a malfunction?
If we're in a simulation (and I'm not saying we are, but bear with me), what would a glitch look like? It would probably manifest as something that defies the usual physics. Something that phases in and out of reality. Something that witnesses describe with wildly different details because the 'object' is rendering differently to different observers.
Spring-heeled Jack was never caught, never photographed, never conclusively identified. He just... faded from reports. Like the simulation stopped running that particular subroutine. Thoughts? Am I mad or could there be something here?
