One and Three had gotten into an argument, and One… killed Three using her magic. And when she tried to revive her, Three came out messed up, her value completely screwed up. In an effort to make sure One didn’t hurt anyone else, Two, Four, Five, Six, Seven, Eight, Nine, Ten, and X trapped her in the moon and sealed the escape shut.

One: “WHAT?!… No… NO…!”

One desperately tried to escape the moon, but nothing worked. She then sat there in silence, realizing there was no escape.

One: “No… No, no, no, no, no, no, no, no, no… No…”

She laid down, feeling extremely upset and hopeless. She never meant to kill Three, she was just upset that no one would hang out with her and acted out of anger.

After she was sealed away, the rest of the algebraliens went off their own ways. Well, except for Six, who stayed behind just in case One ever came back.

Timeskip to BFB 30, April 9th, 2021. After fixing the problem with Four and the BFB contestants, Four was about to unmerge with the sun and return to earth with them, when he looked at the moon for a moment, he felt kinda… guilty, for some reason. However, he brushed it off, unmerged with the sun and returned back to earth with the BFB contestants, where they were all having a party for Four, set up thanks to Profily. As they were all chatting, when he heard Flower and Gelatin’s conversation.

Flower: “Good job with Four today, Jelly man!”

Gelatin: “Thanks, Flowey! Y’know, everyone deserves a second chance!”

”Everyone deserves a second chance”. He felt… guilty. He couldn’t brush off the feeling this time. He didn’t know what to do.

[This is when One was still trapped in the moon, feel free to continue the RP!]
