I think its obvious I don't like the idea of Temmie being Flowey in underswap. I don't own undertale
The teen years for Papyrus were hard. Sans told him mood swings were normal. That it's ok to feel a little sad or angry every once in a while, but it's not that simple for him. Switching between happiness to depression, blinding rage to eery serenity didn't seem normal to him. He never saw Undyne or Alphys under go this, sure, his older brother Sans had the occasional mental breakdown, but that was it. Sometimes he'd just- just want to get up and GO and do SOMETHING, ANYTHING! His hands would shake and his fingers would twitch to the point where he kept his mittens on or put his hands into the pockets of his hoodie, he'd pace back and forth in his room and when he was outside his ran for short distances and stopped and walk then ran again. Anything he could think of to release some energy. He'd be like that for weeks and not know why or what could help. Most of the time now a days, he just fell into this lethargic negative mood.
Sans, bless his soul, would act with his mood, encouraging him on his bad days, not complaining or mentioning it when he asked the same question he asked only a few minutes ago, helping him keep his cool, and even covering his shifts when he couldn't get out of bed. It had always been that way, it just wasn't all that bad until he got older.
Being diagnosed with a bipolar disorder after... The Incident... explained a lot.
Sans was diagnosed with a few disorders himself when they decided to go to a therapist after his 1 hp was brought to light after what happened.
Papyrus still felt awful about it. It had been all his fault.
Sans truly is a God send, he has the patience of a saint (the forgiving heart of one as well, only Sans would forgive him for losing his temper like he had. Only Sans would act as if ending up in the hospital for something Papyrus did was his fault, that Papyrus was the innocent victim, not the awful swine he'd acted like.), it's no wonder why the whole town loves him. His consistent positivity, unwavering support, his determination, his belief in others, he was everything anyone could ever hope for a friend, everything Papyrus could never hope to be.
In that hospital sitting by his brother's bed, he realized how small his brother was. How weak he looked. How venerable... His tiny form didn't take up a forth of the bed.
The doctors said he was malnourished, they had asked when he last ate and Papyrus realized he had no clue. When Papyrus was locked away in his room (which was most of the time as both skeletons liked their privacy)Sans took his food to Paps' room. He'd always said he ate before he made Papyrus' plate, so he never thought much of it. He never saw him eat, even growing up he only saw him do it a handful of times.
His brother was starving himself, right under Papyrus' nose. They brother he so often looked up to was suffering in silence.
If that wasn't bad, the doctors told him about old fractures, that there were far to many of, that most of them came from around the same time. They thought they came from his childhood, they where so old.
For as long as Paps remembered, they grew up on the streets, but his earliest memory of Sans was when the oldest was a teen. He never asked about their parents now, never thought about it anymore. When he still did he was little, he was told by Sans that they were good people and that they died in some accident. The former obviously wasn't the case. Papyrus never felt more guilty.
You landed harshly on the bed of flowers, your anger was replaced with suffocating sadness and pain. Why did this happen, why were you doomed to be alone? Why were you doomed to suffer for eternity? Why couldn't you just be loved? You had so much to give and had given, they only threw everything you did into the mud. Insulted you, hated you, beat you... Where you really that repulsive? To the point where you couldn't even try to gain a friend.
It's a dog eat dog world and you weren't strong enough to survive in it.
Your cries echo and bounce along the walls. You sounded as pathetic as you looked, as pathetic as you felt.
"Hello? Is anyone there?" A soft voice called.
You try to muffle your sounds. It could be a bully, they could hurt you or worse.
"It sounds like it came from over here... Oh! You've fallen down haven't you?"
You look up to see a snow white goat wearing a green and yellow stripped shirt. The light made a halo as he stood over you. His voice was to tender and soft, it reminded you of song lyric you heard once. "A voice so sweet, I thought I heard the shuffle of angles feet.", you muttered softly to your self, your voice was so scratchy and hoarse. Compared to his beautiful one. You felt ashamed that you allowed yourself speak when he looked confused as only you heard your whispered words correctly. He asked you if you where alright and told you to stand. He noticed your struggle he moved to help you. When you stood up he but his arm around you and helped you walk. You uttered your name.
He was being so nice, why? What did he possibly have to gain?
"What?", he asked. "My name is Frisk...", you managed to get out with some difficulty. "Your voice! It sounds like it hurts to speak..."
You nod as the two of you arrive at a doorway.
"Frisk, huh? That's a nice name, my name is-"
