The two teleported hand in hand inside of Alphys' lab, frozen in place by the two monsters fumbling around on the couch, quite obviously in the midst of a heavy make-out session if their twined bodies was any indication. There hovering over the yellow dino was a familiar fish monster, their faces inches apart, and from the flushes on their faces, they had been going at it pretty hard. Frisk squeaked and hid her face behind her hands while the two monsters separated, quickly smoothing their rumpled clothes. Sans laughed heartily watching his blushing girl and the two frazzled monsters before a spear whizzed by his skull and an outraged Undyne picked the skeleton up, cursing him for his poor timing and lack of courtesy.

"You just had to show up, huh? Couldn't give us a heads up first.. no, no just have to interrupt when we were just about to get to the good part!"

Alphys blushed and stuttered, the poor thing on the verge of fainting. Frisk was beet red, but went to Alphys' side and pulled her lab coat lightly and gave her a reassuring smile. The two women apologized profusely for either interrupting or being unaware of their surroundings.

Sans had gotten quite an earful from the annoyed fish before she finally dropped him back to the floor and returned to her lover's side.

"So what are you punks doing here anyway?" The fish huffed and pulled her girlfriend back into a loving embrace.

Sans took the liberty of taking over since Frisk had no idea what was really going to happen. He walked over and squeezed her hand gently, sending her warmth and reassurance.

"She has decided to help us power the device. And before you speak, yes I did explain the situation to her. I'm sure you heard from the news that a monster is suspected to be the murderer of the humans who disappeared a while back."

The other two monster nodded, faces falling grim. Frisk carried on, the earlier excitement fading as the seriousness of the situation settled in.

"Yeah, I've been reviewing the files left behind on these men, and although there isn't much evidence to suspect a monster as the culprit, the council doesn't believe us to be innocent. Sans said you need my DETERMINATION to power this cloaking device. Although I didn't expect to have this done so soon, I'll help in any way I can."

"The sooner the better," Undyne agreed.

Alphys had finally calmed down by the end of their talk and she nodded briskly. Guiding the others, she pressed a button by the bathroom door. It opened to reveal an elevator, one that Sans had hoped never to revisit again.

They all got in and Alphys pushed a button. They stood in relative silence until the door opened. Alphys rushed ahead claiming to need to tend to some things before the others could follow.

Sans kept the other two busy with silly puns to distract them from their anxiousness, but despite his pokerface he couldn't deny that this facility gave him the creeps. The whole area was poorly lit with a few lights blinking sadly, the walls a hard steel, almost like a cage, and the place had an odd smell of chemicals and decay. He hated this more than anything, but he kept his cool and prayed this would be the last time he would have to come down here.

Alphys returned about ten minutes later apologizing for the wait. The dinosaur then guided them down various hallways, her steps assured and confident as though she spent a great deal of time down in the gloomy lab. They passed through a room filled with nothing but rows of old rotting beds, a thick musk making them all cover their noses. Alphys dragged them past the room and took a left down another hallway, opening up to a large room with a strange looking machine.

Frisk looked around thoroughly creeped out by the entire facility. It was nothing like the bright, bubbly atmosphere up above. This all felt wrong, the atmosphere was thick, the shadows seemed to grow around them and she could distinctly feel the stares of.. something. Those creatures, the amalgamated, they had been freed had they not? It certainly didn't feel like it, although She wasn't foolish enough to go and find out what lie in the darkness around them. She looked at the massive machine, flinching at the sight. It was a large rusted looking thing that strangely resembled a goat skull, quite disturbing to say the least. Multiple pipes rose outward to who knows where. The darkness surrounding the machine only frazzled her already anxious nerves while she glanced over to her skeleton, her mind buzzing with nervous anticipation.

Sans snapped her out of her thoughts with a bony hand clutching her shoulder lightly. He gave her his famous grin and stuck his tongue out to tease her, and she responded similarly, inwardly appreciative for the distraction. They made faces at one another seeing who could out-weird the other while zoning out in their own little world. The other monsters watched them in confused amusement for a few moments before Alphys eventually cleared her throat and led Frisk away to the giant machine that took up most of the room. She sat Frisk down on the hospital table before giving her a run down of the machine and the process of extracting her DETERMINATION.

"Frisk, you should know what we are about to do. It won't be painful unless you fight us okay? You need to stay calm and still while we take a little bit of your DETERMINATION. Don't fret, you won't have any lasting effects from the extraction, you'll just be a bit dizzy and drained from it. I'll tell you what to do from that room right across the way." She pointed to a room directly to the left of the machine, it had a huge mirror to allow them to see the machine and she could see through it into the space.

She nodded but as Alphys turned to walk away, she reached out and grabbed the monster's hand.

"H-How long will this take? I-I um.. ah.. I don't like tight spaces.." she said incredibly nervous.

Alphys smiled and patted her head gently, "Only a few minutes, ok? Don't worry we will be right next door and we can still communicate while the extraction is going on. You won't be alone."

Frisk nodded and the monster couple left to the control room leaving Sans and Frisk alone for a moment while they checked the equipment.

"Sans.. what is this place? It feels so..."

"Heavy? Scary?" He finished for her.

At her nod he walked over and sat beside her, throwing an arm around her shoulders to pull her closer. "If you don't want to do this anymore then say the word, baby. I won't make you do this."

She shook her head adamantly, "No, we need to do this, Sans. We must protect the monsters at all cost. We all deserve to live aboveground without fear or judgement. This is just one step closer to a better life. A life for you and I.." she whispered softly, a dark blush adorning her features.

Sans blushed a bright blue and he smiled before kissing the top of her head, "Yeah, you're right. I'll do everything possible to ensure a happy future for us."

She smiled and he ruffled her hair before helping her lie back on the operating table. He kissed her lips tenderly before Undyne's booming voice interrupted their moment. He left to the control room huffing at the interruption. Undyne smirked, they had ruined their moment first, so she figured they were even now.

Alphys took the microphone and talked to Frisk through the speakers, "Alright Frisk, just lie there and relax. This won't hurt, but you must stay still and keep calm."

She nodded before looking into Sans' eye sockets for encouragement. He smiled and brought his hand to the glass and stuck out his tongue. She giggled before sticking her tongue out. The machine whirred to life and she felt herself moving backwards into the darkness of the machine. She panicked momentarily before calming down when she saw the different colored lights dance above her eyes. Flashes of pink, purple, blue, green, yellow, and red flitted across her vision.

"How are you doing in there, Frisk?" Alphys voice drifted into her ears.

"I'm okay, Al. Just a bit cramped." She chuckled softly.

"That's good. Now when we start the extraction process, we are going to pull your soul out for a few moments. Don't be alarmed, it is normal. Now we're going to begin, okay?"

"All right, do what you have to do."

No sooner than she had said the words she felt a tugging on something deep within her chest. It wasn't painful, but it was a tad uncomfortable. After a moment she noticed a red heart rise out of her chest stopping a few feet from her chest. It shone brightly in the dim lighting and a smile lit up her face as she recognized the shimmering light in front of her; this was her soul. It was strange to see it before her very eyes, but she couldn't deny that it was the most amazing site she had witnessed. Back when she had been lured into battles, it wasn't nearly as amazing to see her soul since she had to defend it from the hostile monsters, so now that she had the opportunity, she studied it intensely. Her soul was large, big enough that if she could move, she was sure it would fill the palm of her hand. The light within shone beautifully, the red glow pulsing in time with her breaths. It truly was a magnificent sight. All too quickly, a voice broke through the intercom once more.

"So the next part is the actual extraction. You might feel actual bit discomfort, but just remain still and calm okay?"

Frisk did as she was told, silently waiting for it to begin. She didn't have to wait long before she felt something tug at her soul. There was a bit of fear that made her soul waver, and her eyes widened with the increasing worry.

"F-Frisk, y-you must calm y-yourself or else this won't work and you will be in p-pain." Alphys warned, although she sounded to be nervous as well, judging by the slight edge to her tone.

Frisk couldn't help but become even more frightened as worries and doubts began to fill her mind. A slow stinging pain radiated through her left hand, running upwards to her very core and spread out through the rest of her body. With fear running through her mind, the pain only increased, turning from a dull stinging to blazing fire coursing through her veins. She let out a pained scream before hearing the soothing words of her boyfriend come out of the speaker, his words soft and reassuring, yet his voice filled with concern and fear.

"Frisk, baby, it's okay. I'm here. I won't let anything hurt you. Sweetheart, focus on my voice. It's almost over, I promise."

Frisk focused all of her attention on the sound of his voice and found herself slowly calming, his gentle reassurances easing her back into a calm state. He spoke to her of their future, of the hopes and dreams of the monsters. He spoke to her of how brave she was and how he was lucky to have her in his life. His voice stilled the pain she felt, and despite her relaxed state, he didn't stop speaking until Alphys released Frisk from the confinement, sending her soul back into her body once more.

Frisk looked up at the cracked ceiling, crying softly at what had just happened. She blinked her tears away and found herself in a tight embrace, strong arms clutching her to a bony chest in desperate comfort.

"Baby, I'm so sorry! I'm so terribly sorry!" He cried into her shoulder, his face moving to bury into the crook of her neck.

She hesitated for a moment before clinging to him just as tightly, letting herself cry softly onto his shoulder, "I was so scared. I-I didn't mean to get so worked up.."

He shook his head and kissed her face quickly, "Don't you dare apologize. You can't help being scared. I'm just so glad you're okay.."

Frisk smiled tearfully and kissed his teeth before pulling away to see a distraught Alphys and a fearful Undyne. The dinosaur apologized profusely and Undyne wrapped her cloak around the shaking human's shoulders. Frisk smiled at her friends and reassured them that she was fine, just a bit tired and shaken up after that whole ordeal.

Alphys went back into the control room to finish inserting the extracted DT into the large golden bracelet. It took a few minutes before the device powered on, and when it did she walked over to the couple that seemed reasonably calmer now that the danger had passed.

"S-Sans, the cloaking device is complete. A-All we need to do now is put it o-on and I would l-like to j-jot down a few n-notes on the results." She said weakly, handing over the golden bracelet.

He nodded and took the device from her clawed paws, "Let's get out of here though. This is no place for Frisk."

The group silently agreed and they packed up quickly, turning off all of the machinery. Sans noticing how tired Frisk was decided to pick her up into his arms. She squealed in shock, opening her mouth to protest, but he silenced her with a quick kiss. She stopped struggling and merely relaxed against him as he carried her to the elevator, not bothering to set her down until they made it back to the main floor of the lobby.

Everyone filed out of the elevator before fussing over Frisk. She giggled softly, happy that her friends were so concerned over her health. Sans didn't find the situation funny at all, but he just held her hand tightly after setting her down on the little stool by Al's desk. Not surprisingly, there were cup noodles everywhere along with a cute cat girl statue and piles of manga littering the haphazard workspace.

"Now that Frisk is okay and we're all here, Sans you should probably test out the device." Undyne prompted.

He clutched the bracelet in his bony fingers. He took a moment to steady his nerves before sliding it over his bony hand and up past his wrist.
