Just a warning, I won't be following any script here. Conversations will be different, as they would be anyway seeing as how this is an AU in the first place.

"The name's Sans by the way. Sans the skeleton."

"I'm supposed to be on watch for humans right now, but I don't really care about catching any," Sans said with a yawn.

Too tired.

"Now my boss on the other hand, he's obsessed. He'd totally kill ya if he gets the chance. Sooo… I'm just gonna head on out. If he finds out I saw ya and didn't do nothin' he'd beat me senseless. So…"

The skeleton walked up to the gate. He pulled out a key and found the lock hidden carefully between two thorns. He unlocked the gate and swung it open. He grinned and waved at them.

"You guys have fun! Try not to get killed too fast, else boss'll be disappointed. And bored. Both of which are not conducive to my health. See ya later."

Sans walked away. Every bone in his body ached to turned around. To go to her. To stay by her side and protect her. But that wasn't how this world worked. It was kill or be killed. In this world, it was only a matter of time before his precious Light dimmed.

The thought made him stop in his tracks.

Why.

Why did it have to be her.

She didn't deserve this.

What did he know what she deserved.

He didn't know her.

I don't want to deal with this. I'm too tired to be dealing with this.

I'm so tired.

"SANS."

Sans groaned at the sound of his brother's voice. He stopped and rolled his entire head along with his eyes. He pouted at his brother, who was approaching with his usual confidence and head held high. His red cloak fluttered behind him as he walked. His outfit was black and red with spiked shoulder pads, tight pants, and tall boots. Sans was expecting the blow, but did nothing to avoid it when Papyrus' fist came crashing onto his head.

"YOU LAZY BUFFOON! WHAT HAVE YOU BEEN DOING THIS ENTIRE TIME?"

"My job, actually," Sans said.

"THAN WHY HAVEN'T YOU RECALIBRATED YOUR PUZZLES?"

Sans shrugged.

"Their fine."

"THEY ARE NOT FINE! WHAT IF A HUMAN COMES THROUGH?"

"I dunno. How 'bout we find out?"

Sure enough, the human walked into the clearing. Sans watched as his brother's eyes glowed with excitement. For the first time in forever, his brother laughed.

"Will you look at that. A human! Finally," Papyrus said. "At last, I'll finally be able to take Undyne's place as the leader of the Royal Guard. This is perfect, just perfect."

Papyrus cackled.

"Forgive me, I have been rude. I am the Great and Terrible Papyrus. Remember that name," Papyrus smirked. "For it is the name of the monster who will take your soul."

Sans felt a chill go up his spine. Papyrus turned and left without waiting for a response.

"This isn't good," the flower grumbled. "You need to give up this 'mercy' thing. He'll kill you before you even have a chance."

The human shook her head.

"You won't survive if you keep this up! Please, I'm begging you. You have to fight!"

The human hung her head low.

"I can give you some advice," Sans found himself saying. The human raised her head and looked right at him with hope filled eyes. Sans felt his heart melting. "Boss has this blue attack. You'll know it when you see it. When he uses it, don't move. No matter what."

The human nodded. Sans turned and began to walk away. He stopped when he felt someone grab his hand. For a panicked moment, Sans prepared to fire off a Gaster Blaster. He stopped when he saw the human there, with his hand still in hers.

She smiled.

For a moment, Sans felt like that boy again. That scared little boy. Afraid.

Alone.

Sans disappeared.
