It's part 3 of my Undertale trilogy. We finally get to the bottom of the Gaster mystery with our greatest weapon of all -- SCIENCE! We've done a good job of connecting Sans to the Undertale mystery but what about Papyrus? How does he fit into all this? Well Papyrus is a lot less innocent than he appears. So crank up the Megalovania and stay Determined, it's the FINAL Game Theory on Undertale!
