WARNINGS: Past non-con. Nothing graphic in this series, though.

The beginning of the new series! Woo! We're following the story of the game, but with the Underfell twists that I read about when I looked it up. Very Sans-centric though. Definitely not as dark, at least not right now. I have an outline written out, but I have a tendency to change things as I write lol.
Anyways, I hope you enjoy! I want to say that I may not always be able to keep up the updating schedule that I had with the first part. And I suck at puns. I'm trying my best though!

Everything was white.
Not that it was anything new. Everything was always white in the forest outside the Ruins. Honestly, he wasn't sure why they even bothered putting sentries here. No one ever came here and no one ever left the Ruins. It was one of the few areas that was dust free, seeing as how monsters didn't exactly frequent that place since everyone moved. Normally, the sentry closest to the Ruins would be found asleep in his station, but not that day. That day he had felt the need to stretch his legs a bit. Take a walk.
Said need may or may not have been because of the recent time anomalies.
When the skeletal sentry found himself reliving the same events more than once, he had first suspected that damn flower of Alphys'. The yellow lizard had asked for his help the first time he had escaped, but he was too tired to be bothered.
He was always too tired.
But it was different the last couple of times. He didn't know how he knew, but he did. It felt different. Maybe it was the difference between the determination of a soulless creature and the determination of a human. But he knew.
It was why that day of all days the sentry was standing in the woods, a few feet away from the path. His black hoodie was fringed with white fur over his blood red shirt that matched his red boots with black laces. Despite the weather, he stood there wearing block shorts that barely covered his knees. His face was spread in a constant grin, showing off his single, golden tooth among the razor sharp teeth. Should anyone look his way, they would be instantly struck with fear at the sight of his single, red, glowing eye in the dark.
The door to the Ruins opened.
Sans watched from afar as the human walked through, dressed in a black sweater with red stripes and jean shorts that they wer sure to regret later. Something about them stirred something in the back of his mind, but he couldn't place it. They were also wearing a black backpack. It was left open and sitting in it was that damned flower. He looked a little worse for wear, the sentry noticed.
The human jumped when the Ruin doors closed behind them. The flower said something he couldn't hear and they moved on. The sentry stepped out of the trees and began to follow. They were speaking softly as they walked and the sentry noted that they were a little on edge. They practically jumped out of their skins when the sentry accidentally stepped on the branch that had fallen. They spun around quickly, but the sentry blinked away before they could spot him.
He watched from the trees again as they took a moment to panic before moving forward. The sentry stepped out again and began to follow them. They eventually came up to the large, spiked gate the blocked the bridge that led across the chasm. Every spike was laced with a deadly poison and they protruded at every angle. It's creator had purposely made the bars too wide to make it tempting for people to skip through, but one false move and your life would be over.
They noticed him coming. He could see it in the way they had stiffened. The sentry smirked and toyed with the buzzer in his hands. This was going to be easy. He approached, not even bothering to hide the noise of his footsteps. He walked until he was an arms length away from them.
"Human. Don't you know how to greet a new pal?" the sentry asked with a deceptively friendly voice. "Turn around and shake my hand."
The sentry already had his hand out and waiting as the human finally turned...
...and his soul froze.
She was the most beautiful thing he had ever seen. She had brown hair only a few shades darker than her tanned skin. Her eyes were narrow and black and her lips were plump. The only thing missing was her smile.
Before the sentry could process this new information, the human had obediently taken his hand. He tried to bark out a warning, but it was too late. He watched as the electricity raced up her body and to her friend on her back. He watched as the life left her eyes before she crumbled to the ground. She now lay there before him, lifeless. The flower wasn't dead, but he had lost consciousness. Not that he cared.
What he cared about what the human. This figment of his imagination that had come to life. The vision that had faded away long ago.
His light.
The sentry was standing in the trees.
He was in a daze as his soul quivered with regret and confusion. His attention was drawn once again to the Ruin doors as they opened. They were more cautious this time. She kept looking around for threats. Without thinking, the sentry followed. The human didn't even bother to look this time when he broke the branch. He followed them all the way to the gate.
"Human."
She whirled around, weapon ready. It was a toy knife. This time, he noticed the red ribbon tied in her hair. She was on guard, but didn't attack. The sentry noticed that the knife didn't have a speck of dust on it. If it had been used to kill monsters, it hadn't been any time recently. The weapon shook in her hands and he could tell that she wasn't used to handling a weapon of any kind, even a plastic one.
"Whoa there, buddy. No need to be so jumpy," the sentry told her. She didn't seem convinced. "You must have had quite the experience, to be so on edge."
"Like you don't know, you smiley trash bag," the flower grumbled.
"Long time no see, weed," the sentry growled. "I don't know what you're talking about. I mean no harm."
"Oh? And what about that thing in your hand?" the flower snapped.
"Oh, this?" the sentry held up his hand. "Just a harmless joke."
"Yeah. Right," the flower hissed.
The sentry shrugged.
"So. What's your name kid?"
She hesitated.
"Come on, I ain't gonna bite. Okay, maybe a little," the sentry grinned.
"She hasn't said a word since she got here," the flower grumbled. "What makes you think she'll talk to you?"
"Izzat so. I'm guess that means you don't know it either?" the flower didn't respond. "Don' matter, eh kid? The name's Sans by the way. Sans the skeleton."
