"Human! Over here!" Sans called, waving for Y/n to come to his side of the field. The grass was such a dark blue it almost looked black. The echo flowers were strewn about it randomly, creating a beautiful effect. The three friends were in Waterfall, one of the most magical places in the whole Underground.
"I'll be there in a second, Sans!" she shouted back. Her response was repeated by the echo flowers all the way down to the brothers. Sans shouted an "ok" and returned to what he was doing with Papyrus. Y/n received the message and got up, walking towards them when suddenly, she felt a tugging on her foot. She looked down to see a green vine wrapped around her ankle, tightening around her sweat-pant leg. She started to shake a little and followed it down the hill.
At the foot of the hill, she saw a yellow flower spring from the dark dirt. The girl looked back to see Sans fussing at his brother, most likely he told another bad pun. She fought internally with herself for a minute before making her way down to the flower to see what he wanted.
"Golly, it's only been a few weeks and you've already managed to make friends with the most popular residents in Snowdin!" Flowey said happily, uncoiling his vine from her ankle. "How's it going? It's been a while since we last talked, friend."
"Yeah, it has been a while huh?" Y/n said, settling onto the dirt casually, siting cross legged. "Things have been pretty great on my end actually. Papyrus is super nice, and he's a goofball. He and Sans get along very well, it's nice to watch (unless Paps makes a pun, then it's chaos). Sans is awesome, he's super sweet, even if he tries to come off as tough. The first time we met officially he kept going on about how he'd capture me through his brilliant "riddle trap" techniques. When I passed them all he got kinda down though. I offered to be his friend and he jumped at the idea. We've been on good terms since, though he says that one day he wants to battle me to see how strong humans really are compared to monsters." She let out a little laugh, hoping she'd never have to fight someone... and definitely never have to fight a friend.
"Sounds nice," Flowey commented. "So... you care about them?"
"Of course I do!" Y/n exclaimed, a little too quickly. Flowey's expression was unreadable.
"Do you know anything about the Royal Guard?" Flowey asked.
That's random...
"I know they're searching for human souls. They work for the Queen, Toriel," she replied. "I think that's it."
"Hm, you got it mostly right," Flowey said. "They also don't take treason to well."
"What do you mean by that...?"
"I mean, you're a human right? And the Royal Guard is hunting for humans! If they found you hiding with the two skeletons they'd take you away and possibly... hurt them." He paused to let his words hang in the air. The thought had never occurred to the girl until now. "The punishment for treason on this scale would be death, I think. Holding the one thing that could free the entire Underground from captivity."
"But Asgore said my soul wouldn't work because I'm- I'm an adult," Y/n said, stuttering at the violent thoughts that raced through her mind at the small conclusion. That... children... had been killed for their souls. "The Queen and the Royal Guard wouldn't have any use for me."
"A human soul is a human soul, Y/n," Flowey said in a kind of sing-song voice. "If they found you, they'd kill you and Papyrus and Sans without another thought. After all, in this world, it's kill or be killed."
She let his words and phrase sink in. Asgore had lied to her before, about the basement, it was entirely possible he had lied to her about this to give her a false sense of safety. Perhaps she and the skeleton brothers were in danger. What could she do about it? She could run away and live on her own. No, that'd be pretty selfish. But staying with them was equally selfish. She let out a heavy sigh, bringing her head up from its previously hung position.
"What should I do about it then? What do I do now?"
Flowey's vine wrapped around her torso, moving her body by force to stand up. "Meet me here later tonight and I'll give you some advice," he said, a pleasant smile still on his face. "But don't tell them about it ok? It's supposed to be a secret!" Y/n nodded. Flowey said a quick "good-bye!" and burrowed back into the earth.
"HUMAN!" The girl stumbled forward as she felt someone tackle her from behind. "Where were you?! You didn't come when I called you! What gives?" Sans exclaimed. Y/n laughed and hoisted him up, holding onto his legs and walked up the hill piggy-back-style.
"I was looking around and found another echo flower is all," Y/n replied with a smile. Sans looked at her perplexed. "It was a really interesting conversation." She gave him a reassuring smile. He smiled back and tightened his grip around her neck.
"Whatever you say, I trust you. But you owe me a bedtime story when we get home!" Sans exclaimed happily.
"Why? What'd I do wrong this time?"
"You made me wait of course! And you didn't eat my tacos today, you usually always eat them," Sans said, as if it was the most obvious thing in the world. "And now you owe me one bedtime story."
The two had reached the top of the hill. Y/n abruptly let go of him, which was a bad idea. Sans didn't let go of her neck in time and ended up pulling her down with him. Y/n landed on his front. "Gah! Human! Get off me! I can't breathe!"
"You don't have lungs you idiot!" Y/n snapped, rolling off him anyway, giggling at the situation she had created. "Pff- sorry Sansy. I didn't mean to fall on top of you. (also, I have a name ya know)."
"Ugh don't call me that!" Sans snapped, rolling onto his side so they were face to face now. "I'm an adult, and as such I have no need for such childish nicknames." Y/n snorted, then burst into a fit of laughter. Sans tried to stop himself but ended up laughing alongside her.
Papyrus walked over to the two and looked down at them lying side by side in the grass. "You two are such goofballs," he commented, shaking his head and smiling. He used his magic to lift Sans from the ground and put him on his feet. Y/n soon got up and brushed herself off, not wanting Papyrus to use his magic on her. "Alright, if you two are done rolling in the grass and flirting, let's get on home. I'm bone tired..." Papyrus yawned and started walking down the hill.
"W-we're not flirting Papy!" Sans exclaimed, his skull flushing as blue as his eyes in embarrassment. Y/n found herself flustered as well and simply walked after the other brother.
That idiot. Pff. I know better than to flirt with his brother; I know he'd kill me if I did.

I hope this was ok :)
It's more of a filler I know, but I wanted to get more acquainted with the world (and for those of you reading who've never played this game).
