even at my worst? / even at your worst. by necropathy, PerpetuallyTired_PT

Summary
Nightmare is unraveling.
He doesn’t know what’s wrong with him. The touch of his lovers makes his teeth itch. Their kindness makes him want to scream. Something inside him is festering, tender as a bruise and twice as sweet. Suffering calls to him. Misery clings to the air like perfume, and it leaves him wanting. That alone is enough to terrify him.
And when he finally snaps—tendril tight around Killer’s throat, spine nearly breaking beneath his grip—he likes it.
His curse runs deeper than he knows, rooted in his marrow, coiled tight around his soul. It feeds on his empathy, twisting it until pain tastes sweet and suffering makes his mouth water. He retreats. He lies. But it doesn’t stop.
It’s up to his lovers to drag him from the dark, and feed the thing that’s driving him mad.

Summary
Error clutches Cross’ sweater to his ribs, shivering as he feels the phantom touch of imaginary Cross. The Cross in his mind crookedly smirks as if in response, leaning teasingly closer to the imaginary Error’s pelvis as the telltale glow of building magic can be faintly seen through his pants.
Gasping, Error closes his sockets to try to escape his own mind, his bones warming as his magic gathers at his joints. However, instead of escaping, Error is thrown into another scenario; Cross, settled between Error’s bare legs and looking at him with a hungry glint in his mismatched eyelights. -

Summary
One day, Geno went missing. No one knows where he went or what happened to him, not even Reaper. At least, that’s what everyone thinks.
Nightmare begins to get suspicious when Error becomes more flighty than usual. He comes to conclusions that aren’t necessarily correct nor incorrect.
These two statements are more interconnected than they appear at first glance.

Summary
For the UT character bonanza prompt: Breakfast
Error nearly closes the portal for good to continue working on his puppet to spite his hunger when he finds himself staring as a classic Papyrus stands at the stove. The Papyrus is wearing an apron with “COOL COOK” written on it in sharpie as he cooks what looks to be pancake batter mixed with spaghetti. It shouldn’t be appetizing, and normally Error’s sure it wouldn’t be. Yet for some reason that he’s obvious too, he finds himself reaching through to grab the plate of finished pan-ghetti-cakes sitting to the side.
“AH AH,” Error freezes, confusion and rarely felt shame stirring in him at the scolding tone.Or, Error eats breakfast with two skeletons who feel strangely familiar.

So it’s with a smile that he can’t bring himself to attempt to hide and a twinkle in his eyelight identical to Error’s that Geno steps into his role.
Or alternatively, a lesser known symptom of being left isolated in a void is the awakening of your inner theater kid.
