Third Person POV

Swap Sans smiled and laugh with his new friend, Fell Frisk, as they were happily chatting with each other. They were both sitting by one of the many lakes located in the Waterfalls as they continued to talk, their feet dangling in the water.

"Its weird talking to Sans, who isn't Sans, yet is Sans..?" Fell Frisk giggled.

"INDEED I COULD SAY THE SAME." Swap Sans smiled. "I AM QUITE USE TO MY HUMAN'S USUAL ANGRY TONED VOICE."

"While he growls in annoyance." Fell Frisk closed her eye.

"AS SHE SMACKS YOU IN THE HEAD." Swap Sans sighs.

"Calling you and idiot."

"THEN PROFUSELY APOLOGIZING RIGHT AFTER."

"And its really cute how they still try to act all tough and strong on the outside-"

"-EVEN IF THEY ARE REALLY SWEET AND KIND ON THE INSIDE."

The two laughed as they both had identical bright smiles. The two knew very well what it was like to be someone like that. They each cared deeply for someone like that, truly something they had in common. They each were reminded of their own Sans and Frisk.

"I would be interesting to have a conversation with your Frisk later. She sounds just like my Sans." Fell Frisk said.

"FROM THE SOUND OF HOW YOU DESCRIBE YOUR SANS, THEY DO SEEM SIMILAR IN A WAY." Swap Sans responds. "MY HUMAN HOWEVER REALLY IS A SWEETHEART."

"Sweetheart..." She beamed, sighing.

Sweetheart. A nickname which Fell Sans had always used whenever addressing the sweet Fell Frisk. As much as she insisted he call her by her actual name, he simply ignored or refused. Arguing that the nickname suited a kindhearted soul such as herself.

"HMMM?" He tilted his head. "HUMAN ARE YOU ALRIGHT?"

Snapping out of her thoughts, the chocolate brown haired girl laughed sheepishly as she scratched her cheek, away from where the bandage that covered a small wound.

"I-I'm sorry. I was just reminded of my Sans." She says her hazel brown eyes stared at the ground. "You see, sweetheart is a nickname he gave to me ever since we meet." She explains, cheeks heating up in embarrassment.

"I SEE..." He grins. "I KNOW WHAT ITS LIKE TO BE GIVEN A NICKNAME." He says. "MY HUMAN TENDS TO CALL ME 'BLUEBERRY' OR JUST 'BLUE' DEPENDING ON HER MOOD."

"Depending on her mood?" Fell Frisk says, curiously.

Swap Sans nodded his head. "SHE TENDS TO CALL ME 'BLUEBERRY' WHEN SHE'S HAPPY, EXCITED, OR JUST IN A GOOD MOOD. SHE CALLS ME 'BLUE' WHENEVER SHE FEELS BORED, LAZY, ANNOYED, OR IN A SAD SORT OF MOOD." He explains. "THE ONLY TIMES SHE ADDRESSES ME BY MY REAL NAME IS WHEN SHE'S SERIOUS, ANGRY, NERVOUS, OR IN A EXTRA GOOD MOOD. IT VERY RARELY HAPPENS HOWEVER."

Swap Sans' smile widened with each word he spoke as he thought of all the memories he had with his precious human would happily call his name.

"Interesting." Fell Frisk says as she held her pointer finger up. "Does she realize that?"

"I BELIEVE NOT." He answers. "WHETHER SHE REALIZES IT OR NOT, IT CAN BE VERY USEFUL." He winks.

"Seems like it would be." She let out a quick giggle. "I'm glad I ran into you Sans. Its always nice making a new friend." She says.

"I AGREE." He says.

"Anyways." She started. "I'm interested to know more about your world. Is it alright if you tell me more about it?"

"ONLY IF YOU SHARE SOME INFORMATION ABOUT YOUR WORLD AS WELL." He says.

"Deal."

They two continued to talk about their worlds and about their loved one, bonding happily, as their smiles never left their faces.

~~~With Swap Frisk and Fell Sans~~~

Swap Frisk observed from a distance, behind a wall, her sweet blueberry talk to a different Frisk near the edge of a lake, her hands balling up into a fist.

'She must be from this timeline...' She thought.

She could see him smile in delight as he continued to talked to the girl. A small sting of pain was felt in her heart as her hazel brown eyes trailed down to the ground. She had left for only a few minutes and the next thing she knew, Sans had started talking to a random Frisk from probably this timeline. She tried not to jump into any conclusions as she knew Sans better than that.

"Hey." A voice suddenly said, snapping Swap Frisk out of her thoughts.

She turned around to find a similar looking skeleton to her blueberry, but at first glance, she immediately knew he was completely different. He wore a crimson red shirt with a black jacket over it, black basketball shorts with yellow stripes. His eye sockets were shut while he scowled, baring his pointed teeth as his back was leaned against the wall and both his hands buried deep in his pockets.

Fell Sans soon opened his eye sockets revealing his bright red eye sockets to Swap Frisk. He turned to face the human, his expression showing nothing but annoyance, making Frisk take a step back. It was odd and unusual for her to see some who mirrored blueberry's appearance, yet looked and acted like the complete opposite of him. His expression was hard and stern, and she didn't like how he stared at her.

"Hey, is that your Sans?" He angrily says, gesturing towards the two figures that sat by the lake.

"Ya so? What's it to you?" She retorted.

"Do ya mind keeping him away from my human?" He chuckled darkly. "I don't take kindly to those who mess with my sweetheart."

Fell Sans felt a surge of jealousy run through his body when he saw his innocent Frisk talk to a random Sans, as his left eye socket began to blaze a bright crimson red color, starring back at Swap Frisk with a wicked grin plastered across his face. Swap Frisk growled as she instinctively brought her knife out, her hazel brown eyes beginning to glow a light red color.

"Dare touch him and I'll make sure you and that little Frisk of yours never see the light of sun again!" She spat out.

"Ya wanna mess with me, human?" Fell Sans taunted as he slowly walked towards Swap Frisk.

"Bring it on skeleton! I'lL FUcK yoU UP!" She growled, clearly pissed off.

How dare he think he would even try to harm her Sans! She held her knife up defensively as she waited for him to do something.

Fell Sans didn't like how this Frisk was speaking to him. He also didn't like the fact that she brought out a knife on him. He always did have a temper, but his Frisk was usually there to calm him down. The thought of his Frisk's sweet smiling face urged for him to calm down as he took a deep breath. He knew that his Frisk wouldn't want him to get into another fight again.

"Listen here human." He started, furrowing his nonexistent eyebrows. "I don't want any trouble. Just take your Sans and go back to your own timeline."

"I would gladly leave this hellhole with my blue- uhh... I mean Sans." She says, crossing her arms.

Fell Sans then noticed that she wasn't even looking at him anymore, her gaze was now focused on the two figures that sat by the lake, feet dangling in the water. He noticed that for a moment, her expression was soft.

"But he's smiling..." She softly says. "I wouldn't wanna remove that smile of his face..."

Fell Sans snickered. "Funny. Didn't expect someone who just earlier looked like she was about to end my life by slicing my head in half, to suddenly sounding so weak and so vulnerable."

"Sh-shut the h-h-hell up!" She growled, face reddening as she glared at him before facing away from him.

Swap Frisk could feel her face heat up in frustration and embarrassment. God she couldn't believe she just let her guard down for even just a split second in front of a complete stranger. She mentally face palmed.

'Stupid.' She thought to herself.

"Well, I can't say I disagree with ya there."

Swap Frisk then noticed that Fell Sans wasn't even looking at her anymore either, his gaze was focused on his Frisk as she continued to chat with her Sans. For a little bit, she noticed his expression to began to soften.

"Don't tell me your gonna start getting all emotional on me here." She held back a snicker.

"Ha, ha, ha. Yes I can feel my tears falling down my skull already." He rolled his eye sockets.

"Awww! Does the big baby need a hug." Swap Frisk mocked, extending her arms out.

"No." He bluntly said.

Swap Frisk wanted to burst out into laughter, but she didn't as she saw that Sans didn't even spare her a glance.

"Ya know? I want to rip that skeleton away from my sweet human and toss him into the lake." He begun.

Swap Frisk growled.

"But I can't. I can't be the one to rip the smile of her sweet face." He murmured. "So he's safe for now." He let out a small grunt.

Then they stayed silent. Both were to busy watching their significant other laugh and talk as they didn't even realize that they smiles began to form on both their faces.

Swap Frisk began to lean against the wall as she watched her sweet blueberry smile brightly, putting away her knife. His smile had always felt contagious to her, no matter what the situation was, she hated how easily seeing him smile made her smile.

"It really is hard being the one to rip the smile of their face." She said.

She was surprised by what she said, but she couldn't think of a way to take it back.

"Mhmm." Fell Sans nodded his head, still not even turning to look at her as he once again began to lean against the wall, closing his eye sockets. "Because all you want to do is make them smile."

"Make them laugh." Swap Frisk closed her own eyes.

"Make them happy." Fell Sans chuckled.

"Protect them."

"Care for them."

"Love them."

"Beat the crap out of anyone who harms them-"

"-Or even just insults them-"

"Because who would even dare try to harm them."

"And whenever your the one who harms them-"

"-You do whatever you can to make it up to them."

"Because you don't wanna lose them."

"Or drive them away from you."

" Or make them hate you."

"Because..."

"Because..."

"You love them..."

Then it was silent. Both of their eyes shot wide open as they turned to face each other, their faces both flushed an identical red color. Then they both let out a small growl as they glared at each other.

"This conversation never happened."

"What conversation?"

"Exactly."

"Hi Edgy!"

"HUMAN THERE YOU ARE!"

Swap Frisk and Fell Sans turned back to see Fell Frisk run up to them and Swap Sans smiling brightly, trailing right behind. Fell Frisk tackled Fell Sans into a tight hug as she nuzzles her face into the fluff of his jacket. Fell Sans smiled down as he embraced her back, running his boney fingers through her soft chocolate brown hair as he rest his head atop her's.

"So this is where ya run of too, huh sweetheart?" He says. "I've been looking all over for you."

"Oh I'm sorry. I hope you weren't looking for long." She apologized.

"Nah, it wasn't long." He says, placing a small toothy kiss on her forehead. "No need to worry."

Fell Frisk felt that fuzzy feeling in her stomach as she let out a small nervous giggle. Fell Sans sighed, he loved hearing her sweet laugh, like melodious music too his 'ears(?)'.

Swap Sans meanwhile was practically squeezing the life out of Swap Frisk as he hugged her tightly.

"B-Blue... air..." She managed to breath out.

"OH. I'M SORRY!"

He immediately let go of her as he sheepishly rubbed the back of his skull, smiling lightly. Once Swap Frisk caught her breath, she smiled a little as she shook her head and extended her arms out.

"Hey. I didn't say you had to stop the hug, bonehead." She said, cheeks beginning to flush a light red.

Swap Sans didn't hesitate to pull back Swap Frisk into another hug, but he made sure that he was much more gentle with his hug. Swap Frisk gladly wrapped her arms around him, hugging back, as she unintentionally snuggled closer to him and closed her eyes, sighing.

Fell Frisk, still in Fell Sans arms, turned to her side to find her new friend hugging close to him a girl who looked to be a copy of her. She saw how happy he looked and it made her smile.

"H-hello. You must be Frisk... or uhh... me..?" She shyly greeted.

Swap Frisk simply nodded, eyes narrow. Fell Frisk shifted uncomfortably as she noticed Swap Frisk stare. Swap Frisk on the other hand, gripped onto Swap Sans' shirt hard as she still hugged him, staring at Fell Frisk.

"Uhh... i-i-its nice to m-meet you." Fell Frisk stuttered, putting on her most convincing smile.

Swap Frisk still continued to glare slightly at Fell Frisk. Swap Frisk let her eyes quickly flash a light red as a warning to her. Fell Frisk let out a small squeak as she sunk into Fell Sans arms. Fell Sans shoot Swap Frisk a glare as she simply huffed, burying her face into Swap Sans' chest.

'Is she really suppose to be me?' The two girls thought to themselves.

"And you must be the other me!" Swap Sans cheerfully said.

Fell Sans just rolled his eye sockets and turned away from him, leaving Swap Sans confused as he tilted his head slightly to the side.

"I think its time for us to leave." Swap Frisk says.

"I agree." Fell Sans says.

"Awww!"
"AWWW!"

The two friends looked at each other as they smiled.

"Bye berry! See you around!" Fell Frisk bid her friend, waving.

Upon hearing her call Swap Sans 'berry', earned Fell Frisk a deadly glare from Swap Frisk as she scowled and making her tug onto Swap Sans arms and ushering him to start walking.

"FAREWELL HUMAN!" Swap Sans responds.

As both pairs began to walk towards opposite directions from each other, Swap Frisk and Fell Sans gave each other one final glare before turning around and continuing to walk.

·~·~·~·~·~

Bonus!!! (Cuz why not X3)

~~~With Swap Frisk and Swap Sans~~~

"This is why I don't help Undyne with her experiments." She huffed, crossing her arms. "We end up in the weirdest situations!"

"ITS NOT THAT BAD." He says.

"Were in an alternate universe!" She exclaims. "We still have like half an hour before the effects of whatever she made us drink bring us back to our world!"

Swap Sans smiles as he grabs on of Swap Frisk's hands and intertwines his fingers with hers. She looks up at him, making her bite back a smile.

"AT LEAST YOU CAME ALONG WITH ME." He says, lightly kissing the girl's cheek.

"Ya. I don't know how I'd feel knowing you were transported to some random universe. Especially with how eager you can be when meeting monster." She muttered the last part.

She then looked at the ground as they continued to walk. All Swap Frisk could think of was how happy her blueberry was earlier with that other Frisk. It annoyed her that the memory kept bugging her and kept making her feel this weird emotion. She wanted to bang her head against a wall and make this feeling stop. Swap Sans noticed the sudden change in atmosphere as he gazed down at his precious human and saw her staring at the ground, seeming to be in deep thought. He knew exactly what she was thinking off.

He stopped walking as he then placed her chin in between his thumb and index finger, making her look up at him. Before she could utter a word of protest, he proceeded to press his teeth against her lips and closing his eye sockets. Obviously surprised by the sudden action, Swap Frisk was in a bit of a daze. Slowly she began to close her eyes as she wrapped her arms around his neck, pulling him closer to the kiss. Once they pulled away, Swap Sans kissed Swap Frisk's blushing red cheeks as he smiled down at her.

"YOU KNOW I LOVE YOU AND ONLY YOU FRISK." He says, reassuringly, his grip on her hand tightening slightly.

"Y-y-you i-idiot!" She shouts covering her blushing face. "Give me a warning next time you decide to kiss me!"

He chuckles as he brought her in for another kiss. As flushed as she was, Swap Frisk wrapped her arms around his neck again and kissed him deeper.

"God I love you so much you idiot." She breath out as the pulled away.

"I LOVE YOU TOO, HUMAN." Swap Sans smiled brightly. "NOW LET US FIND SOMETHING TO DO TO PASS TIME."

"Alright." She replies, smiling.

~~~With Fell Frisk and Fell Sans~~~

Fell Frisk was happily humming a song as she continued to walk hand in hand with Fell Sans. She noticed the silence that surrounded them thicken as she then looked up at him.

"Its a beautiful outside. Wouldn't you agree?" She says, smiling.

He was silent.

"So uhhh... why were you looking for me?"

"..."

"Edgy? Are you okay?" She asks, concerned, as she tugged on the sleeve of his jacket.

"..."

He stayed silent.

She felt worried that he wasn't answering. Had she said something wrong to anger him? Annoy him? She had stop humming as she stopped walking, causing for Fell Sans to stop walking as well. She let go of his hand and walked in front of him, confusing the skeleton.

"I-I'm sorry if I said something wrong to a-a-annoy you." She said, bowing slightly.

"W-what?!" Fell Sans says, startled. "N-no! You didn't say anything wrong sweetheart!" He quickly says.

"Why won't you talk to me then?" She ask.

"I'm just... thinking." He quietly says.

"About?"

Fell Sans then began to mumble something inaudible for Fell Frisk to hear. He felt to embarrassed when he realized what he was thinking of and the fact that Fell Frisk was now asking him what he was thinking. Fell Frisk began to get and idea of what he was saying when she faintly heard him say 'berry'.

"I'm sorry, come again." She said, biting back a smile.

He began to mumble again as his face began to blush a light red color. She then began to laugh as she covered her mouth.

"Whats so funny?" He growls, confused.

She stops laughing, but her smile stayed, as she stood on her tip toes and gave him a quick peck on his cheekbone, making his cheekbones blush an even darker shade of red.

"I'm sorry." She says. "Its just... its really cute whenever you get jealous." She giggles.

"J-jealous?!" He exclaims.

She laughed again before she pulled onto the fluff of his jacket, making him bend down as she pressed her lips against his teeth. Speechless for a moment, Fell Sans stood there motionless before he came to his senses and began to kiss back, pulling the human girl closer to him. When they pulled away, Fell Frisk delightfully embraced the skeleton as she nuzzled closer to him.

"Berry and I are just friends. No need to worry." She assures him.

"Good." He grins. "Because..."

She giggles, rolling her eyes. "I'm your and only yours."

"That's ma girl." Fell Sans says, ruffling her hair.

"Now, where are we going?" Fell Frisk asks as they began to walk again.

"To Grillbys. I owe ya a date, remember." He replies, winking.

Fell Frisk merely smiles as Fell Sans grabs her hand and intertwines their fingers, making her face flush a light red as they continued to walk together through the Waterfalls.
