"I want to make my brother happy." Sans said looking her straight in the eye. He was serious.

"That doesn't count! You have to pick something YOU want to do!" Papyrus jumped up and down.

Sans threw his hands up in the air.

"But it's really all I want!" He protested.

Papyrus was about to tell him to pick something else when Kate butted in.

"Hey, it's fine! I think it can make do." She said calming and faced Sans. "So the question is HOW do you plan to make him happy?"

Sans frowned. He didn't know, so he shrugged.

"I don't know. I just.."

"But you already DO make me happy!" His brother told. "I'm happy just to have you and you're nice and sweet and cool and a good brother and..."

Kate giggled.

"There's a lot of ways to make people happy. Making them laugh is one of the easiest ways."

"Sooo.. I have to tickle him?" The smaller skeleton tilted his skull.

"Not necessarily! There is more ways to make people laugh. Like, acting silly or goffy or tell a joke or something." Kate pulled out her ponytail, just to remake it.

"What's a joke?" Papyrus asked.

"A joke? Uhm... A joke is.. when you say something, with the intention of making others laugh. I guess. There's lots of different types of jokes. 'Knock knock' jokes, quiz jokes, puns.. Oh! I could teach you that! A pun! That's easy. A pun is a play on words! Liiiike.. uhm... I.. I'm reading a book about antigravity. It's impossible to put down!"

Kate threw her hands out to the sides and waited for a response... which never came.

"Okay? It must be a good book." Papyrus said awkwardly.

"No no! I mean.. it's a joke! It's not serious! It was a play on the words 'antigravity' and 'put down'. You get it? Because.. antigravity and gravity is opposite and.. put down? no? I'm a geek! Not a comedian." She sighted as if she had given up.

"Oh!" Sans gently hit his upwards turned palm with the bottom of a fist, as if he had gotten an idea.

"You mean that the book can't physically be put down because of.. antigravity! I think I understand! Somwhat..?"

"Oh! Good! Now, try to make one yourself!" Kate clapped her tiny hands, either out of excitement or relief that she hadn't totally failed with her poor attempt to be funny.

"Me? Oh, okay. Uhm.." Sans scratched his chin for a moment before he came up with something.

"Uhm.. Papyrus?" He asked shyly.

"Yes brother?"

"I.. I'm glad I have you.. without you I would feel... BONEly?" Sans cringed at his awful attempt.

"I think you meant to say LONEly, brother." Papyrus corrected him.

"No, Papyrus. I think he rhymed 'lone' with 'bone' and replaced it. And it's funny because you two are skeletons! You have bones!" Kate said and pointed at his own arm.

"Oh! ... heh." Payrus gave a weak laugh, which just made Sans smile from ear to ear. Even though he had none.

Those two were just too adorable!

Later, when they had gotten bored of telling bad jokes, they decided to play tag. Kate, having the advantage of being in good shape, didn't go all out on the young skeletons. Not that they noticed.

Sans sat down on the bed from exhaustion and were quickly joined by Kate.

"Hey... *huff* are you having fun?" She asked as she heaved for breath, just like him.

He nodded with a smile upon his face. Papyrus ran up to them and asked them to go for yet another round.

"Heh.. Sorry Papi. We don't have as much stamina as you. I think we're just gonna take a break." Kate kindly refused. She were pretty fit but the stamina of a young boy were no kidding matter. Besides, she hadn't done much physical exercise since..

She looked upon Sans were smiling content while observing his brother. Somehow he was not tense around her anymore. She didn't think she completely had gained his trust, but it was a start.

Gaster had just returned from the bathroom, where he carefully had washed his hands. If anything from the garbage dump came in contact with any of the stuff in the facility, without being sterilized, who knows what kind of germs would linger.

He needed help with carrying some stuff so he decided to go and fetch Miss Anderson for assistance. He walked up to the barrier and were pretty choked of the sight that met him.

All three of them standing in the middle of the room. Subject 1 and 2 were starring intensely at Miss Andersons naked skin! He had caught her in the act of pulling up her shirt to flash her stomach for the test subjects.

"What.. in the underground.. are you doing?" He asked as he let the handprint-scanner, scan his hand and let the barrier disappear.

Kate looked up shamelessly, not bothering covering up herself.

"Oh, hi Doc! I was giving a lecture about human biology! We've just covered the subject of intestines and body fluids." She giggled when Papyrus poked her stomach with a bony finger.

Gaster were quiet for a moment.

"But.. why?" He then asked.

Kate giggled again and finally let the shirt fall.

"Well I guess it all started when I wanted to take a shower and told them not to look. They then asked 'why?' and I said 'it's because I'm female' and then THEY said 'what's a female?' and I said 'you know, genders? The difference between being a boy and a girl' and they just stood there so I realized they hadn't yet to discover the subject of gender so I began explaining the difference, but I kind of lost them when mentioning genitalia and... to make a long story short. One answer led to another question and so on and now we're here!" She flashed the doctor a huge, innocent grin, while he just stood there totally baffled.

"But, Kate. You actually didn't finish what you said about 'genitalia' because you had to explain what flesh were, first!" Papyrus pointed out.

"Oh yea! I almost forgot! So you see, as a woman I have.." She didn't get to finish her sentence, as the doctor literally dragged her out of the room.

"Okay, I'll see you two later!" She bid goodbye and let the doctor drag her to the office.

When they finally stopped, he put his hands on his hips and starred her down.

"Did you need help with something?" She asked innocently and smiled up at him. Their height differences were pretty contrast.

He sighed deeply.

"Two things!" He held up two fingers. "First off.." He retracted one finger. "..Do not fill their heads with unnecessarities."

"They are not unnecessary! I would never turn down a question from a pupil, willing to learn!" She held a hand over her heart as if the words were some sort of codex.

"Secondly.." He held up two fingers, again. "... What in the entire undergrounds did you tell subject 2? He have suddenly stopped complaining, most of the times, while testing and almost don't ask any questions anymore!"

Kates smile didn't fade for even a second, but Gaster could still fell the change of atmosphere.

"I told him what he needed to know. What he wanted to know. Nothing more or less." She took a step closer. "Why? You are asking as if it were a bad thing."

Gaster got chills down his spine. Somehow this woman.. this girl sounded pretty sinister for a moment there.

There, Gaster! Get it together! He though for himself.

"I'm not saying it's BAD. I'm saying that it's unnecessary to explain them anything. Lying isn't needed either. It doesn't matter what they think, as long as they follow orders." He put his hands in his pockets.

"If it doesn't matter then why are you against it?" She smirked. He didn't.

"Just do as I tell you." He ordered and went to pick up a box. She quietly followed his example and picked one up herself. As they walked down the corridor, Gaster realized that the strange feeling hadn't left. He looked over his shoulder to discover that Miss Anderson were observing him.

Not looking. Observing.

What IS it, with that woman? He though as they reached their destination. This was gonna be a long day.
