“SANS, DID YOU FIND THE SHADOW?” Papyrus suddenly asked, jolting Sans out of his thoughts.

“Yeah, but its not at all what I expected.” Sans was unsure how much he should tell Papyrus but he felt too lazy to lie. Papyrus nodded.

“I wonder why it’s causing the disappearances.” Papyrus murmured, as though waiting from an answer from Sans. Sans blinked. He hadn’t asked that. Now that he thought about it, he was sure that Cordis was defiantly behind the disappearances. Why hadn’t he asked about that? Sans’s head began to throb. Why did he still feel the need to trust and care about Cordis, knowing he had nearly kidnapped Undyne and had hurt her so badly. Sans found himself trying to come up with reasons as to why Cordis might have done it. Something was wrong with him but he wasn’t sure what.

“I-I don’t know.” Sans wasn’t sure how else to react. Sans suddenly found Papyrus’s face quite close to his. A bright blue flush darkened Sans’s cheeks and he silently willed it to go away.

“Sans, what’s wrong?” Papyrus was certainly observant.

“I-I…” Sans didn’t know what to say. He knew something was wrong with him but he wasn’t sure what. He felt his magic stir uncomfortably, as though hunting for what was wrong. Papyrus’s right eye glinted orange for a split second and Sans could feel the other perform a check.

Sans

LV: Unknown

ATK: Unknown

DEF: Unknown

HP: Unknown

*Something is wrong.*

Papyrus sighed. Sans was curious as to what his check had said but he also wanted to know what was up with Papyrus.

Papyrus

LV: 1

ATK: 100

DEF: 20

HP: 680

*He doesn’t know what’s wrong.”

Sans figured that the check Papyrus had done hadn’t yielded any results. Papyrus locked eyes with him.

“Sans, do you know what’s wrong?” It was a straightforward question that Sans didn’t trust himself to answer vocally, so he merely shook his head. Papyrus nodded and seemed to be silently pondering something. What though, Sans wasn’t sure. Papyrus moved away a bit, before moving in quickly and kissing Sans’s forehead. “We can figure this out together, just talk to me.”

“Ok, Pap.” Sans muttered, looking to the side.

“Sans, I don’t mean later.” Papyrus grabbed Sans’s chin and turned his head so he could look into his eyes. Sans purposefully didn’t look at Papyrus’s face. “Sans…” Papyrus had a dominant note in his voice that made Sans whimper. As an Omega not actually related to Papyrus, he had always instinctively thought of Papyrus as a potential partner but in all honesty wanted to stay siblings. Papyrus didn’t command attention in a room, he didn’t like to as, despite common belief, he didn’t like everyone’s attention on him. So he hid his dominate aura, which he had despite being a Beta, as best he could, mostly behind a cheerful, innocent facade. Papyrus wasn’t completely innocent, Sans knew, but he was still more innocent than most. He sometimes let his dominate aura leak out when he wanted to know something, along the lines of what was happening now, or if he wanted Sans to do something, like dishes. Sans instinctively loved when he did but he had never showed any indication before hand. Sans didn’t know why, but he felt completely at the others mercy. The whimper seemed to have surprised Papyrus and thinking he was going to mistake it for a sound of fear or pain, Sans hugged Papyrus. His empty mug falling to the floor with a soft thud.

“Stay, please.” Sans’s voice was muffled and slightly hushed as he nuzzled Papyrus’s chest. Papyrus sighed.

“I wasn’t going to leave, but why did you whimper?” Sans froze and flushed, Papyrus had always been curious and observant.

“I-um-I, that is...I...like when…..” He mumbled the last few words.

“Sans, please say it at a volume I can hear.” Papyrus laughed.

“I-I umm…...like..i-it w-when y-you……..te.” Sans muttered.

“When I let my control of my aura slip?” Papyrus interpreted. Sans nodded. Papyrus raised an eyebrow bone, a bit more of that aura slipping out, Sans didn’t know if it was on purpose or not.

“Y-yes….” Sans replied, his face dark blue. Papyrus chuckled, a warm sound. Papyrus gave Sans a soft, kind smile. Sans resisted letting out a sigh. Papyrus suddenly pulled Sans onto his lap, the now empty plates having already been set aside, Sans’s tail twitched and he fought a yelp.

“I have always known you're an Omega. I live with you and you are my brother, almost mother considering you did raise me.” Papyrus pulled Sans into a ball then curled around him.

“P-Pap?” Sans asked, flushing in embarrassment. Papyrus said nothing. Sans grew more flustered by the second, he was being coddled like a baby and he was older! Sans found that his chin was gently grabbed by Papyrus and turned upward at Papyrus’s face. Sans was sure his face was as blue as a sapphire. Teeth suddenly clicked softly to his forehead for a moment once more before pulling away.

“Sorry I didn't tell you that I knew that you were an Omega before.” Sans hugged Papyrus tightly.

“There’s nothing to be sorry for.” He whispered, tears on the edges of his eyes. His mind suddenly swirled and it was like a veil had been lifted over his eyes.

“Sans, are you sure you don’t know what’s wrong.” The final piece clicked into place.

“Pap, the shadow put me under a love spell. He tried to get me to marry him, he obviously needs my power but can’t take it by force. Pap, we need to find out who he is.” Papyrus looked at Sans curiously, anger hidden well behind his eyes, if Sans hadn’t known him as well as he did, he wouldn’t have seen it.

“Who?”

“I’m not going to say his name aloud, names hold power. Especially Latin ones. We need to speak with Asgore and Toriel.”” Papyrus blinked.

“Alright? Let’s go.” He seemed confused but went with it. They both had already been ready to walk out the door, so Sans teleported them into the Judgement Hall, his Judge clothes teleporting onto him. They landed behind a pillar. Asgore, Toriel, Undyne, and Alphys were all there. The souls hovered over them, visible only to Sans. Sans gestured for Papyrus to stay put and he emerged from behind the pillar.

“S-Sans?” Alphys asked. Sans didn’t bother to change his voice but just nodded, exaggerating it to almost a bow of his head so it could be seen. Toriel and Asgore let out small gasps of surprise. Then Papyrus walked out.

“Sans! You stop being so mysterious, it’s weird. We all know its you so stop hiding.” He said it in the scolding manner he always did but the tiniest bit of his dominate aura laced his words, Sans slipped off his hood.

“Sorry Pap.” Sans smiled lazily as he usually did before turning to the others seriously.

Mom! We couldn’t feel you! What happened? Patiantice was freaking out, as he did when worried. Integrity pulled him into a hug, well as best as she could considering she was just a soul.

“Asgore, Toriel, I need to speak with you. It maybe the key to the disappearances.” They’re faces grew serious.

“What is it?” Sans pulled out his notebook and wrote something down. He calmly walked up to the monarchs and showed them it.

Quod Peccatum Cordis Tenebrosi
