All of Snowdin awoke to hear Frisk scream.
The first to burst outside to comfort the distressed child was the shopkeeper and her children. The shopkeeper had brought her frying pan in case the cause of Frisk's terror was dangerous. But instead, they just found the girl at the edge of the forest, crumpled in a fetal position. The children called out for help because they noticed a noticeably large cut on Frisk's right side. Sans and Papyrus, soon followed, running out of their house in their pajamas to comfort their friend.
Papyrus: "FRISK! OH MY GOD, WHAT HAPPENED!?"
Sans: "were you in a battle? did someone hurt you? are you okay!?"
Frisk had to put together a string of sentences through her mental breakdown.
"T-there w-was this r-r-room... a... a b-basement wh-with c-cold w-wa-walls, and... all this *hic* b-blood and.."
"frisk... where was this basement"
Frisk hesitated to answer, but she didn't want to lie to her friends a second time.
"It w-w-was behind *hic* the h-house.. I-I..."
"it's alright frisk... just calm down."
"WHAT ARE YOU TALKING ABOUT SANS!? THIS IS NO TIME TO CALM DOWN AT ALL! FRISK IS SERIOUSLY HURT!"
"you should get her some bandages, pap. before the wound gets infected"
Papyrus was about to object, but he glanced at Frisk's wounds and went to do as his brother asked.
For Frisk, the events leading up to her going to sleep went by like a blur. But the moment she laid her eyes shut, she fell right into another vision. She was in the battle room. And she saw the black blob make its way towards her again, taking a now familiar form.
"Gaster?"
"It is good to see you again, Frisk. I... sincerely apologize for these recent events"
F: "It's alright I guess."
G: "Well, I will have to ask you to return to that room."
F: "What!? NO! I am NOT! do you realize what that... that THING in there did to me!?"
G: "I promise, whatever you saw in that room will be gone. I can assure you"
F: "how can you promise that? You don't even exist!"
G:"because I was the one who created it."
F:"WHYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY-
G"WOULD YOU PLEASE BE QUIET AND LET ME EXPLAIN!?"
G:"Thank you."
F:*quiet whimper*
G:"Now, what was in my room was one of the amalgamates that I created during my career as the royal scientist. They are some my most stable connections to your reality. I was trying to use it to give you more instructions but... the creature had other plans. And again, I apologize."
F: "I still have a lot of questions. What do all those items in the room mean? What do they have to do wth Sans? Why did Sans keep all this from me!?"
G:"All of your questions will be answered, after you do one last favor for me."
F:"And what is that?"
G:"Before i left your plane of reality, Sans took part as a test subject in my research. Sadly, the experiment was never completed, as he was unwilling to see my point of view. I want you to complete the last part in my experiment. I promise, if it works, both you and Sans will not have regretted it. It's a simple task, really."
Gaster stretched out his hand. A syringe, as well as several vials of bright red liquid, appeared in his palm.
"take these vials of liquid determination with you. Then, when Sans is alone with you, take the syringe and inject the serum into him. Do it quickly, to have a better chance of it working. You need to keep him standing for at least a minute, no matter how unstable he gets-"
F:"How unstable he gets!? What will the determination do to him!?"
G:"Well, I'm not exactly sure. I have performed this experiment with other monsters and... they... well, they melted, to put it Bluntly."
F:"MELTED!? NO! ABSOLUTELY NOT! I AM NOT GOING TO LET MY FRIEND MELT FOR YOUR RESEARCH! YOU SICKO!"
Frisk tried to run, but she felt numb, and couldn't move an inch.
G:"Now, as for the matter of your noncompliance, I have something that will persuade you to think twice about your jumping to conclusions..."
