Sorry that it took so long and that it's lazy/short.

Time Skip

Alphys entered the room Sans was in and turned on the light. It's been two days since Sans was brought in to properly rest and now, he could finally leave, but when she turned the light on, he was gone."Sans? Sans!" She ran down the hallway and into a room where she had the cameras. She soon spotted Sans running around in the forest near Snowdin and called Papyrus.

"Papyrus! Sans is running through the forest near Snowdin! I need you to bring him back here before something happens!" She shouted into the phone."ALRIGHT. I'LL GET HIM." He then hung up and Alphys returned her attention to the cameras. Sans was running around and stopping every once in a while to look around. Almost as if he was looking for something.

Meanwhile

Red got a text saying that Classic was in Underfell. He immediately ran out of the lab and started searching. He wasn't in Waterfall or Hotland, so that leaves three areas. Snowdin, Dreemurr Castle, and The Ruins. Classic could be in any one of them and he's already tired from searching all night, but he shoved that urge aside for after he finds him. He wasn't in the town of Snowdin, so maybe he's in the forest. Red ran into the deeper parts of the woods, knowing that no monsters go there. They're afraid that someone's going to be there to attack them, so no one ever dares to step off the path. That makes it easier to look for him.

He heard a rustle and spotted Classic sleeping in the bushes."Heh. Of all the places. At least it ain't somewhere stupid." Red said as he picked up Classic. He teleported into the lab where he was staying and set Classic down on the bed. He quickly picked up his phone and called Nightmare."Hello?" Nightmare asked."I found Classic. Is Nyala okay?" Red asked in a concerned tone."She's alright. She's actually hugging me right now, so no need to worry." Nightmare replied."Alright. Thanks." Red then hung up and crawled next to Classic. He pulled him close and hugged him before falling asleep.

Later

"SANS!" Red jolted awake and saw Papyrus. He pulled Classic closer while making sure he could breath."WHO IS THAT?!" Papyrus asked. Red's sockets widened when he remembered what happened earlier this morning."Oh shit." Was all he could say. Papyrus reached for Classic, but was stopped by a hand slamming down in front of his. Papyrus looked at Red, who was already sweating and obviously scared."L-look, I may not be the strongest monster, but if you think he's just s-some... e-easy XP, then.... then you've got another thing coming!" Red said as he started to shake. Papyrus could tell that he was scared, but he still seems willing to protect the new skeleton. Papyrus moved his hand away and Red slowly moved his, but he was still watching his every move.

Alphys came in and saw Red almost lay on top of another skeleton, as if he was trying to protect him. She came over and tried to pull Classic out of the bed, but Red quickly smacked the bedding right next to her hand as a warning."Mine." He said. Classic stirred and looked at Red."Morning, Red." He said. Red lowered himself so he was now completely on top of him."Going back to sleep?" Classic asked."ACTUALLY, YOU'RE GOING TO GET UP AND TELL US WHERE YOU CAME FROM." Papyrus reached for Classic again and tried to move the blanket off him. Red grabbed the blanket and put it back, earning a small laugh from Classic.

"SANS, STOP." Papyrus tried again and this time, Red flopped onto Classic and rested his head on his chests. He let out a tired and annoyed groan, making Classic laugh more. Red had his back facing Papyrus and Alphys when he started to fall back asleep."Heh. Goodnight, Red." Classic said as he patted his head.

Classic turned to Alphys."I'm sure you want an explanation, huh? Go ahead and ask your questions, just be quiet." He said as he slowly sat up."First, how do you know my brother?" Papyrus asked, trying not to be loud."Well, he's actually my husband. Why wouldn't I know him?" Classic asked."HUSBA-?!" Classic managed to cover Papyrus' mouth without waking Red and looked down at him. His head was now laying in his lap and he looked pretty peaceful."How did you get in here?" Alphys asked. Classic moved his hand from Papyrus and leaned against the wall."Well, I ended up in Snowdin and our boss told Red about it. He brought me here and we both fell asleep." He replied.

"Makes sense." Alphys said."Who are you?" Papyrus asked."For now, just call me Classic. I'm going to go to sleep." Classic replied. He leaned against the wall and put his hands on Red's back. He soon fell asleep and Undyne ran in."What's going on?!" She asked.
