In Love With The Enemy (Undertale AU Multiship Story)

Killer's Knife

~Sans' POV~

"...Hey, Edge..."  I said nervously.

Edge walked towards me slowly.

"I repeat, what are you doing in my house?" He said, his face cold and showing hatred towards me.

"Um... waiting for you brother..." I said, looking towards the stairs, where he'd not returned from yet.

Edge glared at me before turning to the stairs and shouting. "FELL? FELL, ARE YOU UP THERE?"

After a few seconds, Fell responded. 

"U-uh... Yeah, bro?"

Edge rolled his eyes and snorted in disgust. 

"Get out of my house. Both of you." He shouted.

A few seconds later, Fell came back down the stairs, shoving something in his pocket as he went. I couldn't see what it was, though.

"I see you found it funny to break down my door." Edge said curtly.

"Indeed I did. I don't regret it either. Just makes up for all them broken bones, doesn't it?" Fell laughed coldly.

Edge, yet again, made a noise of disgust. "It's 'all those broken bones', not 'all them broken bones'. Get an education,  won't you? It's getting harder to even call you my brother." 

"Okay, so maybe I wasn't an A plus English student, but at least I ain't a complete jerk," Fell hissed, "Come on Sans, we're leaving."

As I passed Edge, he muttered 'insignificant, unintelligent creatures.'

"Yet I got better grades in school than you." I said as I walked past. 

"Really? Are you sure of that?" Edge hissed. 

"Yup. Fell, go!" I could see that Edge was about to lash out at one of us.

Fell and I sprinted out the doorway, but I felt something grab the hood of my jacket. Obviously, it was Edge.

~Fell's POV~

"Get off him!" I yelled at my brother as he grabbed Sans.

Edge glared at me before a small smirk appeared on his face. Before I could do anything, he punched Sans, directly in the jaw. 

Sans winced, but got up, and instead of running, he took a step forwards.

"You wanna fight, buddy? I mean, I was trying to be friendly, but we can do it your way." Sans said coolly. 

My brother growled before summoning a bone attack, sending it flying at Sans.

"EDGE, STOP!" I shouted, running forwards.

Edge, however, sent a bone attack at me, telling me to say back.

Sans, who had dodged the attacks that had been thrown at him, was standing boredly, waiting for Edge to do something.

Edge growled, turning back to Sans. He sent even more bones at him, which Sans easily dodged again. 

Edge braced himself for Sans' attack, but it never came.

"What, you done yet? Was that it?" Sans said with a small laugh.

"Are you not going to fight back?" Edge asked coldly. 

"Nah. Too much effort. But if you've got anything other than a bone attack, send it my way, buddy." Sans said confidently.

"Don't underestimate him." I mouthed to Sans when he briefly looked at me. But in return, I just got an amused smile.
