Frisk was approaching the Final Corridor. Though currently paying attention to Flowey's story, the excitement was already rising within her. She was finally done with the journey and finally at her destination. All she had to do was get through Flowey's story...
"Why am I telling you all of this?", he asked. No answer, but it was rhetorical anyway. He went on, "Chara, I said it before. Even after all this time... You're still the only one that understands me. You won't give me any worthless pity!"
For Frisk, it was reassuring to know that Flowey was still on her side, even if it's just because of a mistaken identity. At the very least, she had one friend of the five - at most - monsters left in the Underground.
Flowey continued. "Creatures like us... Wouldn't hesitate to KILL each other if we got in each other's way. So that's... So... that's... Why..."
Suddenly, neither of them liked where this was going. Regardless, the flower continued digging himself deeper.
"I... I've changed my mind about all this. This isn't a good idea anymore. Y-you should go back, Chara." But Frisk wasn't backing out now. She was finally so close to the only monster she hasn't fought in any of her timelines...
"This isn't funny! You've got a SICK sense of humor!" And with that, Flowey left. The last thing standing in her way was gone. The final obstacle overcome. It was finally, finally time.
The Final Corridor. Frisk couldn't hold her excitement anymore. With no reason to keep up their genocidal facade, she let out a smile, hastily saved, and started walking to the other side of the hall until Sans was suddenly in the room.
"heya. you've been busy, huh?" Once again, the question was rhetorical. In her excitement, Frisk forgot Sans wasn't in on her motives. Believing Sans would misinterpret her smile, she quickly hid it.
He asked another question, but all Frisk could think to do was walk closer, which didn't help the situation at all.
"here's a better question. do you wanna have a bad time?" This time, Frisk almost opened their mouth to answer. Though, this was also rhetorical; he cut her off to continue.
"'cause if you take another step forward... you are REALLY not going to like what happens next."
Frisk was really going to enjoy what happened next.
Author's note: So, I assume it's obligatory for me to say this is my first fanfic. Special thanks to peer pressure for driving me to submit it.
