The Archargent Jack Noir's fourth fenestrated wall was stolen, presumably by Grandpa, much to his intense annoyance. The fourth wall was later located (and broken) to show MSPA author Andrew Hussie for a shameless self-insertion into the story as well as a verbose recap of events to that point. The fourth wall was then taken by Jade as her future self advised via Karkat. She then used it to escape the scratched session with John, Skaia, and the kids' four planets.
