You and Abaddon were two immortal demons trapped in the bodies of twin Victorian Children due to possessions that went wrong. After your accidents, you both resided in The Undervale. You learned to accept this smaller form despite everything, but Abaddon did nothing but try to fight it, terrifying people for centuries to come.

As the years passed by, one family moved into the hotel where you and your brother resided. The Freelings. But out of all the people, Katherine was Abaddon's main problem. She was a single mother to Ben and Esther and was stressed out from the hotel and Abaddon's shenanigans. So she took you and your brother out into town. You and your brother were in two red car seats. You were sitting there trying to calm your brother down who was crying and screaming, trying to break out of the buckle.

You three got to the town as Katherine started panicking, thinking about what to do with your brother. So she tried to put him in the trunk as a rival of hers, Charlie, came up to her which distracted her. You and Abaddon ran to the playground which later turned into terror. Katherine heard screams, and as she ran to the playground, she saw a ton of kids attacked and terrified. As Katherine ran over, she noticed you holding on to Abaddon as he was screaming, trying to get out of your grip.
