As the demon approached him Sans decided he needed to speak his mind.
"Why?" he asked.
"Why? Why what?" they responded, shocked, as he was going 'off script'.
"Why do you do this. Why do you put us through this hell? Why kill us over, and over, and over? What do you gain? What changes? How many times have you tried to kill me...only to die!?"
"You know that Sansy!" they giggled, grinning the evil grin,
"Heh heh. Do you know, the definition, of insanity?"
"No, why dont you tell me Sansy?" still giggling and grinning
"Doing the same thing over, and over, and over. All the while believing something will change. Heh heh, Guess that makes us insane huh buddy?"
Sans began the fight again, not bothering to say the lines he had said before. Instead, he spoke his mind as his attack continued.
"I... I am tired. Heh, not that surprising I know but I did not mean that tired. I... am more mentally tired."
His turn was continuing on and on, as was he. Papyrus was in tears, Undyne look like she might be too. The way he was talking, explained why he did what he did. Why he was, who he was.
"I do not want to keep fighting, but, I must, if I want to see my friends again. My brother, again. I cannot let you erase us. I can't."
Tears were forming in his eye-sockets, turning to steam in his left eye-socket.
"Have you ever had a family, kid? Have you ever had someone you love? Have you ever wanted to protect them? Heh. DO YOU KNOW WHAT IT FEELS LIKE WHEN THEY ARE RIPPED FROM YOUR LIFE OVER AND OVER!? I would guess not. Otherwise you would not be doing this to us."

Undyne was crying now. All three spirits were crying. Papyrus wanted to run over and hug his brother. His attack was still going, and it seemed to be getting even more powerful as the spirits showed emotion. Other spirits were showing up too, they had wandered around for a while, and ended up at the hall. All were shocked to see who was fighting, all were sad and crying as he told his story.

Sans knew his magic should have run out, but it seemed like it was beginning to overflow. More bones were forming than he ever could summon.
"Let me tell you a story kid, if you even are a kid anymore. It starts, 20 years in the past, I was only 10 when my family fell apart. Mom was too weak when she had paps. I never blamed him, she was going to fall within a week anyway. Dad, well, he couldn't live without her. But he knew we needed him, so he tried to live without her. Angel above how he tried. He kept going for three years, slowly turning to dust before my eye-sockets. Then, one day, he did not wake for breakfast. We were alone. I dropped school, and started working. I never could make more than just enough for food, clothing, and the rent. The previous royal scientist, our uncle, was helping us through this time. Then, when paps was 8, he died too. I had to take up multiple jobs just to get Paps an education. Fast forward to now, and Paps has died to your hand over 100 times, I tried so hard to stop you, and I could, but you kept resting. So, I gave up."
Both his eyes were shining now, steam was billowing out of his eye-sockets. His attack was getting more and more powerful, more bones, more blasters. He should have realized, like the demon who was nearly dead and out of breath had, that his one attack had lasted longer than the the total time of a normal fight, but, he was too caught up in his emotions.
The hall, kept in pristine condition, was now almost destroyed. Tiles were smashed, snapped, punctured, bloody, scorched, and melted. Most of the pillars towards the entrance to the hall were destroyed. The entrance area, due to lack of supporting pillars, had caved in. All the windows were smashed through or shattered to pieces. A visible aura of energy was forming around Sans.

Nearly every dead monster's spirit was in the hall, watching from the sidelines. All were crying to a degree. The squeamish had turned away. The rest looked on in hope. Sans can win this.

Sans felt DETERMINED. He felt as if he had the magic of the entire underground at his fingertips. As he felt his body breaking apart, he also felt determination keeping it together.

The demon felt their power slipping. Suddenly it was gone and the let out a scream of rage as everything faded to black.

Sans felt a new power appear to him. Time stopped, and two options appeared.
CONTINUE RESET this was the Demon's power! He could bring everything back!
CONTINUE RESET and as everything faded to black, the last thing he heard was the demon's scream of rage.

CLIFFHANGER!

This chapter was a pain to save. Every time I tried my internet died on me. I think it hates me. When I did save my chapter my computer decided it wanted to die and I lost this outro. I think it's in on the plan to annoy the living crap outta me. Another thing, I have decided that 'Intermission' was a terrible chapter due to the lack of content and effort put in and therefore I banished it to the lost realms of my trash bin for the good of the internet. I also decided to heed the helpful words of a wise Anonymous user and thus I shall go back to the other chapters and rearrange them in a way that makes it easier to read and follow what is going on. Thanks again everyone for the kind reviews and clever constructive criticism.
