Dust POV (I think that's his name correct me if I'm wrong please!)
'Everyone, is gone, I have all of the LV. That ki- no MONSTER, can't win, they never will. Their is only one person left. My closest friend, (Y/N). She is the only one preventing me from my goal. I don't want to, but I HAVE to. If I don't, they will win. I-I can't let that happen.' I walk up to her and start attacking, I miss every time. She was always good at dodging. Lots of training... She's a tomboy. Would rather get dirty than wear makeup.
(Y/N) POV
Sans started attacking me. Why was he doing this? Papyrus went missing, along with everyone else. I'm the only one left to bring the person to justice, I would get help from Sans, but he wont talk to me, and he has been acting weird, did he....no.
"Sans! Why are doing this? What happened?" He doesn't even reply, I check his stats. ATK: 100 DEF: 100 LV: 97. Doesn't want to...
'Doesn't want to what? AND WHERE DID HE GET ALL THAT LV?! He couldn't have...'
"Please Sans! I'm scared too, but please, don't do this!"
He whispers, ever so quietly,"You sound like him." Who is he talking about? His attacks get stronger.
"Sans! Why are you attacking?" He now looks at me.
"Isn't it obvious?-deep breath- I need more LV, more power, to defeat them. "
I look him dead in the eyes. I'm not afraid of him, I'm worried. His eyes are bloodshot, his smile has faded, his sanity.......

Is gone. This is not the sans I knew.
"YOU ARE NOT SANS! YOURE NOT THE SANS I KNEW, you're not the sans I fell in love with." Tears are streaming down my face, for me that's saying something. His attacks stop, we just stand there. He walks up to me slowly,
"I guess you could say you stabbed my heart heh," he rubs the back of his skull,"I'm sorry, for uh scaring ya." He says as he hugs me. I stop crying.
"You didn't scare me, I was sooooo worried." He shuts my up by giving me a quick kiss. I look at him,"gross." He laughs.
"Well, get used to it." I shake my head as we release the hug.
"I love ya." He tells me.
"Yea you 2." I say back.
