Summary
They had a problem in the castle. Specifically Cross had a problem and Nighymare had to be aware of it. The younger monster seemed to have been having regular nightmares that kept him up and made him misrable during the day. Nightmare had caught him multiple times in the kitchen or lounge due to his own odd (nonexistent) sleeping hours.
He surely knew Nightmare knew, but never seemed interested in acknowledging it. On the few occasions their paths would merge, Cross would mumble an apology about being up so late and scurry away. It hadn't started to affect his performance in the field *yet* but it was only a matter of time. So tonight, Nightmare decided, he would approach Cross instead of observing him from the shadows.

Summary
Frisk had long given up on dreams, on the future, since long before they fell into the underground. Chara never got the chance to dream, other than dreaming of disappearing. But then they both climbed a mountain, and across time, they have become intertwined. There cannot be one without the other. Since they were twelve, they’ve been stuck to each other, and both of them silently hope that they’re stuck together forever.
Come hell or high water, they will grow together. They will heal.
A.K.A. ,

Summary
It's been five hundred years.
Five hundred years of spite and hatred, slowly turning into something more. He grew out of being that small child. He had long since killed the ones who hurt him.
His sweet, helpful, clueless, dumb brother was inanimate now. He would stay that way.
And if that little brother did return, he would be grown, surely.So now, staring at the armed child--and finding no difference between him and what he remembered him to be--Nightmare hesitated.
Why was he so small? -

Summary
“...How much cash do you have on you?” Asriel asks out of nowhere. Chara swivels around to rifle through their wallet.
“Fifteen dollars.” They say, plucking the notes out of the inner pocket.
“Great!” Suddenly, paws on their back, and they almost topple out of their seat; Asriel is pushing them towards the counter. “Now go get us something!!”
He gives them one last shove despite their protests, and they unfortunately stumble right before the barista with the inklike, glazed eyes and that naive, curious look.
or: a deltacharisk take with absolutely nothing nefarious going on! absolutely none! totally!! and i'm definetly not lying!!

Summary
“so, you’re uh…” the blue skeleton in front of Sans had an odd pinched expression.
“an advanced AI” Sans clarified and his social program hissed at him to relax his posture “nothin’ more an’ nothin’ less”
Sans’ analytics quickly gathered the expression of each skeleton monster in the room to come to the conclusion that something was off. He carefully noted the odd atmosphere as the chime of a directive made itself known.
FIND A WAY HOME
Something in him settled and the red circlet at his temple evened out to a mild yellow.
“you sure about that pal?” the first skeleton’s red twin said as he picked his golden tooth after a pause.
“my social programming’s pretty complex, it can be hard to tell i‘m just a machine” Sans tried not to let incredulity sneak into his voice—of course he was sure.
“THAT CAN’T BE RIGHT” a lighter blue skeleton said rather intensely and Sans’ analytics scrambled to see where he went wrong “YOU HAVE A SOUL. RAZZ CHECKED YOU EARLIER”
Sans blinked at the accusation.
Or
Sans is pretty convinced he’s a machine, everyone else is convinced he’s got issues.

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.
