Underfell:

"Ugh, I hate work." Sans sighed heavily, a cloud of hot breath puffing from his mouth and floating in front of his skull. He swished at it irritably with a hand. Grumbling to himself, he burrowed further into his jacket, settling in the fluff of his pulled up hood, shivering against the cold.

"I hate this place. I hate the cold." He growled, exposing sharpened teeth, with one dipped in gold. The rest caught the flickering light of a torch nailed to the boards that made up a crappy bridge his brother had made.

"I hate this bridge." He narrowed his eyes and kicked a clump of snow, grinning a little as it disappeared into the darkness below. That was the only thing that he could come close to liking. Watching stuff fall into that endless void, never to return. Like that dog he threw done there last week. He heading heard it annoying yapping since.

"I hate dogs. Hell, I even hate Papyrus."

"What did you say, Sans?" A gravely voice colder then the winter air reached him, and the short skeleton jumped, his hands clenching in his pockets.

"Uh, nuttin, Boss. Jus sayin how much I despise everyting, but you. Heheh.." He glanced up towards the towering monsters face, instantly lowering his gaze as Papyrus narrowed his eye at him.

He scoffed and turned away, the spikes of his armor swishing past Sans' head, who ducked to avoid being smacked.

"That is right, brother. The Great and Terrible Papyrus is the only good thing about this hell hole. Without me, you would be nothing."

"Only a hell of a lot happier."

"Hmm?"

"Nuttin, Boss." Sans growled as he turned away, leaning against one of the wooden poles nearest to him. His red eyes darted across the clearing in front of him, checking along the dark path for signs of life. Nothing.

"Ain't nobody ever gonna come done this way, you know, Boss? I think we scared the shit out of that last punk so bad that they ran and told everyone to avoid this way."

Sans shook his head, stirring the inside of his hood. He peered over his shoulder to look at Papyrus, who had his back towards him. An extended elbow signified he had a hand wrapped around his chin, his dangerously sharp mouth set in a grim look as he thought.

"I suppose your right, Sans. We haven't seen anyone for days now.. Maybe they all died trying to solve my puzzles." Sans narrowed his eyes at that, setting his shoulders against his cheeks.

"I hate your puzzles, too. OW!"  A swift smack to the back of his head shut him up, and he turned back around, rubbing his skull gingerly.

"Why'd ya do that?"

"Because you said you hate my puzzles!" Papyrus was upset now, his mouth twisted into a frown, his hands on his hips. Sans always thought he looked like a mom when he was angry.

"Well, I do." Sans anticipated another hit, closing his eyes and turning his head, but reopened them after a moment of nothing happenig. He caught sight of Papyrus' back again, this time noticing his head was lowered, his shoulders hunched.

"Boss-"

"Sans, do you really hate me?" The question was so unexpected, that Sans felt like he ha been smacked again. He blinked stupidly, trying to wrap he is he's around what his brother meant. Was this a trick question?

"Uh, yeah. Always have and always will." He stated slipping his hand back into his jacket. He waited in awkward silence as Papyrus stare at the ground in front of him. All the anger was gone from his face, now replaced with a hidden sorrow.

"No, do you.. Hate hate me?" His voice shook this time, and Sans had a feeling that this wasn't a game.

"Well, no, Boss. I hate you, but I don't hate hate you." He cocked his head I the side and waited for an answer, sighing as he didn't get one. He was shuffling his shoes in the snow to turn around , when the crunch of icy flakes beneath heavy boots stopped him.

"Good.." Papyrus said, facing him but not making eye contact. He was rubbing the back of his skull, as if embarrassed, and Sans couldn't help but snicker. This time he got a smack, but a lot softer. Papyrus was back to his normal self, all sinister and exagerated anger.

"Well, get back to work! Humans aren't going to capture themselves, unless their as dumb as you!"

"Hey, that only happened once, and I was drunk!" Sans snarled as he remembered staggering home after downing 4 bottles of mustard to have fallen into a hole that Papyrus had dug outside the town, the fall leaving him battered and peeved. Instead of helping him out, Papyrus had stood there and laughed at him for almost an hour, before chucking the end of a rope at his head.

"Whatever. Just.. Don't do it again. And call me if one comes. I don't want you getting hurt." Papyrus wiped around and stalked away after that, Sans watching his silloulete slowly merge into the shadows ahead of him. That was the closest the skeleton could ever come to sympathy, and it left Sans' soul warm, enough to get him through his shift.
