Misery loves company, but sometimes the company is the source of your misery. I knew why we were both here: Papyrus wanted us here, and because he was his brother and I was his friend, we both felt more than obligated to oblige – even if we were only united in our hatred for each other and desire to be there for Papyrus. Sans was a lot better at acting natural around his brother than I was, though his permagrin made it almost too easy for him – not that he needed the help. He specialized in not letting anyone in, only his brother owning such a privilege, and I was as far removed from his life as he was mine – not that I could ever be far enough from him.

The Nice Cream guy waved at us as we took our nice cream to go, and I checked my watch in between licks. "I have to get going in a minute." I sent a regretful look Papyrus' way, though I was sure Sans was mentally pumping a fist while his hands remained comfortably in his pockets.

I barely caught his curious glance from under his hoodie's hood, but I didn't elaborate until Papyrus gasped. "BUT WE JUST ARRIVED!"

"I know, and I'm sorry, but I have work in a little bit." I took a step backwards, guilt practically spelled out on my face, and shame started to claw its way up my throat when Papyrus' previous grin fell away to pure sadness. I hated breaking his heart – that was part of the reason I couldn't say no to him when he invited Sans and I out despite my distaste for his brother.

"SANS AND I COULD WALK YOU!" He threw an arm around his brother, almost knocking the multiple scoops of ice cream piled high on his cone onto Sans' hoodie.

"That's alright." My gaze flickered down to Sans, who sent me an almost grateful wink – like a silent 'thank you' for not lingering in his presence longer than necessary. But it was just as much for me as it was for him. "Sans will be late for his mid-afternoon nap." He chuckled at that, shrugging when Papyrus shot him a displeased look.

"You heard her, I can't cancel again."

"YOU SHOULD JOIN ME!" Papyrus grabbed the shorter skeleton, practically shaking him in his excitement. "UNDYNE IS LETTING ME TEACH HER CLASS TODAY!" Undyne hosted a dance class up on the surface with the purpose of helping kids channel all that punk energy into something more productive than vandalism, and while the students were troublemakers, they took to Undyne rather well. I knew Papyrus would be fine with Undyne around, but my lips still pulled into an unconscious frown at the thought of him going in the same direction as me.

"You sure that's a good idea, Paps?" Sans asked for me, that same pull of discomfort on his face, but Papyrus only put a hand on his hip as he held the ice cream in the air like a torch.

"I'LL BE THE BEST TEACHER THE ROYAL GUARD'S EVER SEEN!" He still clung to the hope that even now, with the barrier broken years after the monsters made it to the surface, he would get into the Royal Guard eventually. Neither Sans nor I had the heart to tell him to let it go. "AND YOU SHOULD JOIN ME TO TEACH THE HUMANS THE MAGIC OF DANCE!" Papyrus struck a pose that made me smile despite how corny it was but Sans was already shaking his head like I knew he would. He never danced, not even for his brother.
