3 AM UPDATE! Restless night and have nothing better to do? Type up a delayed chapter of a fic you've kept on hiatus for like several weeks... I think...

Anyways!

This chapter was an idea suggested by someone! Thank you for the idea and I hope you along with all the other readers enjoy this! And just so you all know the events in this chapter will leak into the next one so yeah!

ENJOY AND I DON'T OWN UNDERTALE!

Sans was sweating.

Not because of worry or embarrassment. It was not because of the temperature outside or the fact that the sun was beaming on him. It was the fact that he was exercising.

Well even though it wasn't technically exercising because it was just Papyrus lifting him up by his arms and moving them around in a jumping jack like motion… BUT STILL.

Sans huffed and puffed as his brother continued to do this. Never in his life has Sans even wanted or did any exercise. Even when he was a kid he would just lounge around and watch TV. His brother, in their younger years, would beg Sans to come outside and play with him and Undyne but he always refused.

Today was different however. Papyrus and Undyne decided to surprise Sans with some new joggers and sweatpants so he can join them in their training session. The little skeleton gasped for air as Papyrus dropped him to his feet. He bend over and took deep breaths as the fish lady jogged over to them.

"Oh Sans! How can you get tired over a few simple jumping jacks?!"

The smaller skeleton continued to wheeze as her brother agreed.

"Yeah Sans. That was just the warm up portion. Now we have to jog around the block ten times, do twenty five push-ups, twenty chin ups and the combat portion."

"Wait,...there's… MORE?!"

Undyne laughed. "Of course Couch Potato! Now hurry up and catch your breath, we don't have all day!"

She then jogged away, leaving the brothers alone. Papyrus watched her leave before turning to his brother, who was staring at the ground.

"Aren't you coming Sans? Undyne's gonna get mad if we come too late."

"Nope." he said simply before lifting his head up to show no irises and a large grin covered his face. Sans sick smile never wavered as he made his way to the house. Papyrus caught up to him and put his hands on his shoulders.

"Sans, you can't just go! I've been planning this training session for us for months! Not to mention that Undyne held off on her lunch date with Alphys for this!"

"Look bro. that's great and all but you know I don't like exercising. Why couldn't we just find a romantic comedy in the movie section to watch instead?" Sans replied, pushing his brother's hands off of him.

"Because you're always in the house. I wanted us to do something outside together. Don't you want to hang out with me?"

Sans gave Papyrus a small smile. "Yeah. I just… don't wanna be outside… You understand, right bro?"

The tall skeleton smiled back, attempting to hide his sadness. "I understand brother. You can go inside. Me and Undyne can just do our usual training together."

"Thanks Pap!" the small skeleton hugged his brother before making his way to the house. Papyrus' smile drooped to a frown as he watched his brother go. He then turned around and ran off to find his fish friend.

~I~I~

Sans walked towards the front door with guilt piling in his chest. He shouldn't have pushed his brother aside like that. Well, he DID say it was alright. Maybe a good movie could make up for this. He smiled, knowing the right movie to pick out when he notice the spikey vine that was wrapped around the door knob. The skeleton cletched his teeth angrily before looking down at the obvious cause of this.

Flowey was planted next to the door and prevented him from going inside. The skeleton smirked.

"Sup BUDdy! I don't mean to get all in your WEEDS but can you move those?" he pointed to the vines.

"Nice comedian," the flower remarked sarcastically. "but no I won't move."

"Look either move your stupid vines or.." his eye glowed blue. "you're gonna have a bad time."

"You don't scare me couch potato!" Flowey snapped. "I know you didn't wanna train with your stupid brother because you're a lazy bastard!"

His eyes narrowed in anger as Flowey smiled wickedly. "How about make a deal, fatty?"

"What type of deal?" Sans asked,crossing his arms. The plant smirked.

"If you stay out here and train with your brother, you'll prove to me that you aren't a lazy sack of slouching bones and I'll let you inside. But if you refuse or don't comply with my deal, I'll still let you in the house but you will have to trade me your prized possession!"

"NO!" Sans shrieked. "Not my sweater!"

Flowey pouted. "NOT THAT STUPID THING! Your OTHER prized possession!"

"My ketchup?"

"NO!"

"My pet-?"

"IT'S YOUR BROTHER DANG IT!"

Sans raised an eyebrow. "My bro?" he chuckled. "He's my prized PAPsession!"

Flowey gritted his teeth. "JUST DO AS I SAY!"

"Fine, fine."

And with that, he turned back around to look for Papyrus.

~I~I~

After Sans found Papyrus and Undyne. The bros along with the fish did their workout together. Sans was lagging behind for most of the training but he managed and Papyrus was enjoying it. They were in the mist of the combat portion and Undyne and Papyrus were tussling as Flowey popped out of the ground next to a nearby bush. He called the small skeleton over.

"Hey Bone head!"

Sans walked over to the plant and said.

"Sup?"

"You're doing great. That stupid brother of yours is happy and-"

Sans raised an eyebrow and smiled. "Aww you care about my bro? That's SWEET!"

Flowey blushed wildly. "NO I DON'T! THIS WAS A DEAL!"

"A deal?"

The two turned to the new voice to see Papyrus and Undyne standing there. The tall skeleton drooped in misery.

"So you didn't want to hang out with me?"

"Yep!" Flowey cackled. "He was doing this all to get inside!"

Papyrus turned to Sans. "Is this true?"

"Yeah but-"

"I thought you really wanted to train with me Sans. I thought you really wanted to do something with me but I guess I was wrong…" Tears started to form in the tall skeleton's eye sockets as his brother retorted.

"Wait Pap I can-"

But before he could explain, Papyrus had already teleported away. Undyne looked in the direction he was going before looking at Sans.

"Nice one Bone head."

She then ran off, leaving Sans and Flowey alone. The plant laughed menacingly before going back in the soil. Sans turned to where Flowey was before looking back in the direction where Undyne ran off to.

He then sighed. "What have I done…"
