Esther and Ben were finally Abaddon's vessel's age, and Katherine all got them in the same school. On the first day, Abaddon was pretty much singled out for how he acted, and he finished all of his work the minute after it was handed out, since... he's been alive since Earth was created. He knows a lot of things and has no issue with arguing with teachers if they try to call him out.

Soon, Esther gained new friends and invited them all to the Undervale since they didn't mind or think that ghosts haunted the place. Abaddon joined her and Ben, the other five 15-19 year olds just in the lobby. There weren't many people who got rooms at the hotel..

Abaddon soon stated that he was bored and that he was going into the woods nearby. Some guy, with a dark aesthetic, joined him. So, Abaddon led him through the woods.
