This is a possible summary of the text:
The text is a transcript of a video by Game Theory, where the narrator explains his theory about the hidden story of W.D. Gaster, a mysterious character from the game Undertale. He claims that Gaster was the royal scientist who created the Determination extractor, a device that can extract the will to live from human souls. He also claims that Gaster tested the device on himself and shattered across time and space, splitting his brain into two halves that became Sans and Papyrus, two skeleton brothers who have a connection to fonts and timelines. He provides various pieces of evidence from the game to support his theory, such as Gaster's entry number seventeen, Sans' knowledge of other timelines, Papyrus' origin story, and the difference in writing styles between Alphys and Sans in the lab entries. He ends the video by thanking his viewers for their support, apologizing for making it a three-parter, and teasing the next episode where he will reveal more secrets about Undertale.
