It took several attempts. Each more risky than the last.

They had waited until nightfall one night, when they were parked outside of the brothers house, and got to work. Sneaking out towards the car under the cover of darkness.

"It's locked," Frisk said, pulling away from the trunk. "I guess we -"

Without so much as a word, Undyne pulled a bobby pin out of her hair and pushed it into the lock. After a few seconds, it clicked open.

"Ah... when Alphys and I were in our weird crush phase, I found out she thought bad girls were hot so I learned how to pick locks." Undyne sheepishly turned away, popping open the trunk. "But it uh... doesn't matter."

The two peered within the trunk. Nothing. Just a few empty bags, neatly folded into a corner. Reusable grocery bags.

The second time they tried was during the day, when they knew the two would be at work. Still nothing. Undyne had taken a glance towards the house at that time, only for Frisk to shake their head. Not yet. There was a difference between peaking inside of a car and pretending it was unlocked compared to breaking and entering a home where the owners had a restraining order. And probably cameras. Not until they had a better reason to.

They had stopped by the house one final time to try and break into Gaster's car, but had to quickly duck away behind a good chunk of bushes when the front door clicked open. Out walked Gaster, wearing his pajamas.

Soon, a car pulled up. And none other than Jandle walked up.

"Did Sans fall asleep again?" Gaster asked, looking through the cars windshield as he approached. "That's quite adorable."

Undyne leaned forward. Frisk started to chew on their nails, anxiously.

"Isn't it?" Jandle cooed. "Ah, but I'm afraid now isn't the time to fawn over him. Could you carry him inside? We need to have a talk."

"I'll make sure to lock the basement door. We brought home another 'guest', remember?"

Undyne and Frisk glanced at each other.

"A guest?" Frisk asked as the two parents continued to talk, their words becoming muffled by their own discussion.

Undyne frowned. "I think I know what that means."

As Jandle walked inside, Gaster picked up a sleeping Sans and carried him inside. When the front door shut, Undyne pulled out her phone.

"We have to get in there," Undyne said, "They have someone we need to save and..."

And what? What would Undyne do next? If she wasn't caught on the way in, trying to save a terrified monster would ensure she was caught. And they had Sans too. She didn't want to risk anything when they had their hands on him.

"I don't think we can save the person.." Frisk mumbled.

That's right. Not everyone could be saved. Undyne used to believe that she could save everyone with her raw power. The last couple of weeks made her eat her own words, that was for sure.

"We can... we'll have to just take pictures of them for evidence, then," Undyne said, closing her eye. "If we try to save them we'll just end up being caught. But if there's an opening -"

"We try, at least." Frisk agreed.

The advantage of their needlessly giant house was that they never heard Undyne and Frisk crawling in through a window. The downside was that it was extremely confusing. Where the hell was the basement door? If there were cameras - and thank the fucking lord there weren't - there would be several minutes of footage displaying the two wondering about aimlessly.

And this was Undyne's first time exploring with Frisk. She did not anticipate to have to drag them away from investigating everything they saw. Now, she adored the kid, a lot of monsters did, but she was never going to have them help investigate again. They could do that in their own time.

Finally did they find the basement. But they found something else when they quietly descended down the stairs.

They discovered that they were far too late to even hope to save this person.

They were so bloody that their face couldn't even be seen anymore. Several stab wounds littering their chest. Undyne would have snapped a hand out to cover Frisk's eyes from this horrid sight, but Frisk was already walking past her.

And Undyne knew Frisk has seen worse.

"I... fuck man, fuck..." Undyne hissed at the scene. It was awful. What kind of monster would do this to another in their right mind?

She knew from the text screenshots alone that they were insane, but seeing it in person was awful. The poor monster was hanging on by the determination being pumped into their veins, keeping them suffering all the while longer.

Frisk stopped in front of the person, staring up at them. If they even knew Frisk was there, Undyne couldn't tell. Frisk reached forward, and ever so gently grasped at their hand.

"We can't save you, but we can make it end faster," Frisk whispered.

Undyne didn't think she'd ever understand that child. Somehow able to travel around Underground without so much as a break in their face despite the challenges they faced. And here, seeing this type of scene, they pressed forward. Making sure to comfort them first and foremost.

"We need to take pictures" Undyne said.

"Use my phone." Frisk held out their new phone towards Undyne. "I can get away with it, but you're already in trouble with them. If they find your phone with pictures of this, you're gone."

Undyne nodded, but made sure to snap a few photos of the bleeding man on her own phone. Making sure to catch the background of their basement as she titled the camera back.

Guilt captured her soul at this point. She felt awful. Instead of helping this person, trying to help them escape, she was stuck just taking pictures.

No. This was the best option. This person wouldn't survive their wounds without the determination, and Undyne knew that some of Alphys' experiments weren't for the best. The people were alive, but some of their personalities were gone. Mentally dead. Nothing more than living husks of themselves, who - in brief moments of clarity - begged for the release of death. Debate was still going around if this was a humane way to save monsters, or if risking ruining their minds like that was really worth it. And if helping them die would be considered a crime or not.

Even if she did save him, he was more fucked. So, instead, she focused on just taking photos. Gathering evidence. She tried being upfront before, and look where that got her.

Frisk crouched down in the corner, pushing aside a box full of flour bags. Out of their pocket they pulled out a small black device, setting it behind the box before moving it back. A small trail of flour followed the box. Not too noticeable, thankfully. Not unless you knew what you were looking for.

"What's that?" Undyne asked.

"Listening device. Toriel bought some for the Asgore situation, in case she had to use them if he wouldn't confess. She didn't have to use them, though, so no one knows about them but me and her." Frisk explained.

"Oh."

A smart plan, admittedly. Leaving a phone could easily be traced back. And Undyne didn't plan ahead enough to bring a camera. She hadn't been anticipating breaking into their house, but this was a rare chance they couldn't pass up. The pictures should be enough evidence themselves. However, a recording of Jandle and Gaster admitting to their flaws would be the nail in the coffin. Even with their lavish piles of money, they wouldn't be able to escape so many years of bloodshed that was continuing to this day. At the very least, jail was guaranteed.

This was good.

"Wait."

Undyne paused on the stairs, glancing back towards Frisk as they had made their escape. "We should probably go talk to Sans."

"What?"

She glanced around, to ensure they weren't being watched. Good. No one.

"He needs to know I'm on his side," Undyne said. "Sans needs to know I know what's going on and to help us try and get evidence if he can."

"You're right. Let's go."

It wasn't hard to find his room. Labeled, on the third floor. Undyne and Frisk could hear Gaster and Jandle's mumbled whispering from the kitchen, talking about the arrivals of more family. To play with the guest downstairs. In half an hour, Jandle had giggled softly. She was excited. It was awhile since everyone could properly gather. They usually couldn't, not unless it was something extremely important.

Finally did they stumble upon his room. Placing a hand on the wall, she tried to use her magic to feel if his soul was in there, to ensure there wasn't any possible trap, but instead found her magic... unable to work. No, it could work in this hallway. She felt Frisk. But it felt like the wall was somehow blocking her magical abilities altogether.

"Oh."

Undyne drew her hand away, glaring at the wall. They were rich bastards, of course they had access to that.

"What is it?" Frisk asked. Their expression was careful, but confused. Of course they were, not a lot of humans knew this could even exist. Humans didn't live for centuries like monsters did.

"They have magic repellers in the walls." Undyne rubbed at her hand, despite not being injured by the magic repeller at all. "Old fashioned shit. They were used during the war, it's how humans kicked our asses. Looks like they had built their house with magic repellers so other monsters couldn't break in any easier than humans could."

Frisk frowned. "That sounds... why wouldn't everyone know about that now? That sounds like humans could easily overpower monsters anyday."

"It's not exactly common knowledge. The technology was banned altogether, and I was only taught about it because I was Head of the Royal Guard."

Not a good thing for them to have within their house. Undyne didn't know if all of the walls had these devices, or if just certain rooms. If she ever got into a fight here, she'd have to depend on her raw strength. And for all she could know, their fucked up parents could just turn around and suddenly use magic in a place she thought had magic repellers.

The door creaked open, and both peered inside. There Sans was, lying under a thick blanket on a very comfortable looking bed, with his back to the door. Undyne was fast, rushing over to shake him awake. She had been doing a lot of thinking, and though she didn't have enough time to tell him everything she wanted him to know, she wanted to make time in the future.

"Hey."

She shook him firmly. Once. Twice. His eye sockets remained shut.

"Sans, wake up!" She hissed.

Sans didn't even move. He just lay there. As if the sleeping beauty curse grasped at his soul, forcing him into an eternal slumber. She knew he liked sleeping, but Sans wasn't this heavy of a sleeper. He'd wake up after a few shakes. Maybe a loud hiss of his name.

He was just... out.

"Frisk," Undyne said, glancing behind her. "He's not waking up."

Frisk quickly followed up to Sans' bed and reached to lightly push his arm. It fell off his his hip onto the sheets. Unmoving.

"He's asleep, not dead," Frisk concluded.

"Yeah, no shit. But why isn't he waking up." Undyne drew a hand through her hair, squinting down at him. "It's like he's knocked out or something. But his head isn't injured and skeletons are immune to the normal chemical drugs most people use. He'd have to have that magical drug stuff which is super expensive and rare... and his parents probably got their hands on it because they're fucking rich. Of course."

Why was she even surprised anymore. They kept seeming to go lower and lower. And here Sans was before her, drugged and unconscious at his parents house. Did he even consent to being taken here?

Hopefully they could gather enough evidence to ensure jailtime. If they went to court with the pictures now, Undyne knew they would likely get away with house arrest. Especially with their ability to lie up a storm.

And she couldn't even risk leaving a note. His parents might find it first. One bad move, and Undyne was in jail. Which was run by the new Head of the Royal Guard. Which was Jandle.

Of course.

"We'll... have to leave," Undyne said, shaking her head.

She didn't want to risk a sudden visit from his parents. And if they were caught, so were the pictures. She would just have to do this without Sans or Papyrus.

~~~~~~

That night, Jandle paused while washing her hands.

The blood dripped down between her phalanges, slow. Familiar to her. She knew this blood and dust more than she did not having it. And she enjoyed the feeling. Reminded her of the intense desire for life people had. For love.

Everyone needed love. Gaster needed it. Needed her. So did their boys.

Finally. She turned back towards the sink with a soft smile. She had a family. A true family. Built by her own hands, she created the family that was lost ever so long ago. It was nice.

Things were almost perfect.
