What if two humans were in the Underground at once? What if one human was DETERMINED to stop the other? What if they could both SAVE? What happens when an Unstoppable Force meets an Immovable Object? When a certain scientist pulls enough of himself together, he finally finds a way to stop the destruction of his world. All he has to do is break through one wall... (Paranoid rating)

Frisk has fallen into the Underground, but not the one every Frisk falls into. In this glitched timeline, no one is where they should be, and there's an unusual addition. Something is different in the story, the characters, and so on. /An AU of my other story, DoubleTale. I am god awful at summaries 90% of the time. This is one of those times. Paranoid rating./
