You were walking around your AU peacefully, until in the Snowdin of your AU...You saw...An extremely glitched out Sans...Fatal Error Sans...His head suddenly snaps towards you. "W-W-Who are y-y-you...?" Fatal Error Sans would say in an extremely glitched out and raspy voice, as his eyes glow blue and red, meaning he is perfectly stable for now, and won't try to attack you, so it's okay to talk to him...Just...Don't accidentally provoke him, if you do, then you are done for...Be careful with your words and actions...
