When Undyne returned I was out of my body, and I hated it. I know, I have to do it for him, but that doesn't mean I have to like it. It's not just that I was used to having a body, it brings back bad memories. Of back when I thought Blooky wouldn't accept me for who I wanted to be. So I left him all alone. How did I think that was any better?
Undyne ran up to Alphys holding a green chamber thing.
"Alphys! I got it! I got the soul!"
Alphys took the soul from her, "A-Alright, I just have to... um..." she touched the soul to Papyrus' chest, or the part of him that looked like a chest?
There was a flash of light. And suddenly, nothing mattered. I didn't care I was a ghost because the skeleton standing in front of me took all my worries away. I hugged him and he hugged me back. For a few seconds that was all that mattered.
"Papyrus, oh my god!" Undyne yelled, tackling him.
Sans used his powers to fling Undyne off of him so he could hug his brother.
Everyone was happy. Finally. That is until a knife was flung right through my tiny ghost body. That was the only time in my life I was glad I was a ghost.
Sans' eye went blue, and Undyne pulled out a spear.
"wHO THE HELL-" Undyne stopped short and stared at the other side of the room, a look of fear in her eyes, a look of fear someone like Undyne didn't get.
Everyone turned to look at what she saw.
There, Frisk's body was floating, wearing a murderous smile, holding one of the knives Arahc described earlier. We were not getting our happy ending.
