The kid hadn't been looking good, you realized that, but you hadn't realized the extent. After coming inside, you thought if Frisk relaxed and took it easy they'd be fine. You kept a close eye on them, but it wasn't close enough it seemed. As you watched the show and began to zone out, you could feel the weight of the kid's head slowly increase on your shoulder. You looked over and they smiled, so it seemed all was well. But then the kid began to wheeze, and you could feel their body going limp. You twisted around to see what the issue was when the kid falls into your lap, their face twisted with... pain? God that was new. You hadn't seen that since before you had come above ground. You tried to shake the kid awake, but their face and body only grew tighter and tenser. Alphys paused the show, and everyone looked over to see.
"What the hel- HECK- is going on, Sans? We were just getting to the princess with the massive sword!" Undyne looked at the kid and her face turned from anger to confusion.
"They aren't supposed to look like that, right? RIGHT?!" She was standing now, grabbing and shaking the kid with vigor. Alphys stopped her when she too noticed the kid was curling up in pain the more they were moved.
"Th-is isn't right..." Alphys put her clawed hand to the kids forehead, then jerked it back and her eyes grew wide.
"Humans are- aren't supposed to be that hot!" You quickly pick up Frisk and lay them on the ground as gently as you could. You could feel your bones rattling. You remove your jacket from their shoulders and then unzip Frisk's own jacket. Underneath was a sweater just like the one you first met them in... except one major difference. There was a blot of red coming from their side, seeping into the sweater. There was a lot. You look at the kids jacket and you saw a lot of bright red going up the side of the coat too. Alphys put her hands to her face and froze. You look up at her and tried to keep your cool.
"*what the fuck is going on, alphys?" She doesn't say anything, just leans down and puts her claws to the kids side and pushes down. The kid winced and their back arched in pain. Before you knew it you had pushed Alphys off the kid as hard as you could, sending her a few feet back, landing onto her back. She re-adjusted her thick glasses. She didn't look at you. Undyne looked furious, but just as she pointed her fist at you and began threatening Alphys interrupted her.
"S-Sans, c-call Toriel. Right now. Papyrus, Un-Undyne, you gu-guys need to get some hot water and as many towels as you can." You all were shocked. Alphys was ordering you around and hardly stuttering at all. She got back up and lifted the kids shirt. Normally you wouldn't have looked, it wasn't your place, but the white of the bandage wrapped around the kid's waist got your attention first. The next was the blood. There was a lot of it, fresh, emanating all from the same spot. There were other, smaller blotches all down the bandage, but these were old. No, whatever was gushing out the fluid was big and open. There was lots of cuts and scraps, lots of ugly bruises too. All over the kid. You felt your own hand reach for your chest in surprise and disgust. You could hear Alphys muttering under her breath. You didn't look up, you couldn't if you'd tried, but you could hear Undyne and Papyrus' reactions. Undyne was yelling, scared; swearing every other word. Papyrus was silent, but you could almost hear the tears welling up in his eyes. Alphys looked up from the kid and shot death glares at the three of you. "F-Frisk is in danger of dying and you are all st- standing there doing nothing! They need our help a-and they need it NOW!" Alphys' yelling spurred all three of you into action. You whipped out your cell and speed dialed Toriel.
"Oh, Sans! I wasn't expecting you to call this early! Is Frisk ready to-"
"*tori, we need you to come over. right now. It is an emergency." Toriel gasped and you hung up. The kid needed your attention, and Tori would get an explanation when she got here. Alphys began unwinding the kid's bandage. Underneath was hell. Blood had smeared all over the kids stomach and back, covering other cuts, nicks, and bruises in red. The source of the blood looked to have been a deep, deep gash going down the kid's side. Fresh blood was gushing from the wound, and so was white fluid. The flesh surrounding the wound was red and puffy, and it looked painful. God, how the fuck did the kid do it. Who fucking knew how long they'd been like this. How come none of you'd noticed?!. You could feel your eye sockets furrow. Alphys took the blanket she and Undyne had been laying on, balled it up, and pressed it into the bleeding gash.
"*what so you need me to do?" You ask. Alphys doesn't answer. You grab Frisk's hand and hold it to your bowed head. God were you stupid. If you had just paid more attention, if you had just spent those five extra minutes with the kid you might've noticed. Now the kids bleeding out and you were holding their fucking hand being so damn useless. As you internally kicked yourself, in the background you heard Papyrus and Undyne screaming at each other, and loud bangs and crashes as they searched for anything that could be used a towel. You heard Pap filling up something with water, and you could hear Undyne screaming, mostly at herself. They hurried back over, handing a tower of sheets and towels over to Alphys. Alphys didn't even look up. She grabbed a loose towel and replaced the blanket that was now soaked with a fresh towel and pressed down harder.
"G-get a sma-small towel and soak it in the water, the-then place it on their forehead." You didn't even notice. You were so entranced by your thoughts of self-hate and bitterness you didn't even hear the loud knocking at the door. Toriel was yelling.
"SANS? SANS! WHAT IS GOING ON?!" You didn't want to let her in, you didn't want her to see. Toriel had already lost two of her children in the Underground, not to mention the other six humans that fell. Pap or Undyne must have let her in and boy did she storm in. She was just about to give you the scolding of a lifetime, but took one look at Frisk, the child only recently brought into her life and fell to her knees. Pap and Undyne tried to support her, but she could not look away. It took Alphys beginning to swear under her breath did the Queen of monsters rise and go to her child's side. She began trying to heal Frisk's wounds, but it wasn't enough. While Toriel's magic was good for bumps and bruises, this was outside of even a Boss Monster's expertise.
"We need to take them to a human doctor. Now." She said as calmly
as she could, but her voice was shaking. If you recalled correctly, the nearest human hospital was over 50 miles away, there was no way the kid was gonna make it if they walked it. Unless...
"*i'll take them. i know a short cut."
