A/N: Okay, this an extremely short chapter, and I'm really sorry about that! The next one will be much longer, I promise! I had a little fun with this chapter, I thought that it needed some humor to break up the fast action I've put in it. Enjoy! And please review, I could use the feedback!
Chara was cut off by the glowing blue bone shield cast around by Sans, quickly followed by an explosion. Chara shielded her eyes from the growing blinding light, though she was the only one to see it, as she was the only one who hadn't been affected by the blast. Her ears were still ringing though. When Chara opened her eyes again, she was hovering in a white space. The best word to describe it was...nothing. This was nothing.
She started to wonder if this was what happened to HIM. She suddenly panicked, realizing her idiotic partner was nowhere to found. "FRISK! FRISK!" She yelled, to no avail. Her breathing ragged, she turned around and yelled some more. She realized that she was really alone now. A stunned look came over her face as she processed this. This... was worse than being a ghost. Hah ha...Karma is funny. I'm ending up just like HIM, aren't I? I wouldn't be surprised if HE was here.
The tiny ghost sank down on her knees, a forlorn expression plastered onto her face. Her head suddenly jerked up, as she heard a distant yell that became louder and louder with every passing second. What in the name of...?! Chara looked behind her just in time to see a sweater clad, short kid smack into what appeared to be the floor of the void. "Ummm..." Chara said, approaching slowly. She wasn't sure that Frisk was alive. The fall probably hurt them a lot.
Frisk was more discombobulated than anything else. They remembered doing something incredibly stupid, and the blinding white light. Everything had been spinning, images of memories, and their battles, genocide, the surface, all of it felt like it had been ripped out of their brain and then haphazardly thrown back in. Then there was the falling into nothing. They let out a muffled groan, and heard an annoyed sigh from beside them. They raised their arm and used their finger as if pointing something out, and muttered "You know, the invisible floor is a lot softer than you think." They then let their arm flop back down in defeat. Frisk heard an exasperated groan, presumably from Chara.
They rolled over onto their back, clutching their nose, which was a bit red from the sudden impact. (Then again, so was the rest of their body.) They glanced at Chara, who was frowning disapprovingly at them. You smile, but then immediately regret it as you discover that you have a cut lip. Frisk stared up at the nothing above them, and let the consequences of their actions wash over them like a tidal wave. They could only hope that at least Sans wouldn't be dragged down into this abyss. After all, Chara had been fine until your DETERMIINATION woke them from death. And now, you had trapped her in an inescapable prison, where they ceased to exist. Frisk had hoped that the souls could have helped them. They knew it was incredibly selfish, but they had hoped that the souls would sense the regret inside them. They wanted to start over. RESET. Just one last time, to get it right, and never look back. Instead, they had trapped themselves and Chara in the nothing.
They didn't even exist anymore. Now that they were gone, Flowey would once again have the most DETERMINATION, and the fate of the Underground would rest on his whims. Frisk was vaguely aware that tears were streaming down their cheeks, clouding their vision down to a watery blur. Their body started to heave with silent sobs. The young child sat up, and buried their face in their striped sweater as their fragile body was wracked with uncontrollable bawling. It was their fault. They had damned themselves and Chara to a life of nonexistence. This was their fault.
If only you hadn't taken that knife.
If only you hadn't RESET.
If only you hadn't succumbed to curiosity.
If only you hadn't made them forget.
If only...
If only...
