you came from a long line of exorcist and your family expected the best from you but being Lydia's friend you couldn't just send her best friend Beetlejuice to the depths of hell back where he came from even if you both didn't get along you trie to make it work and you kept it a secret for a pretty long time from your family being friends with both a ghost and a girl who you naturally found amazing
Lydia was the peacekeeper between the three of you even when you had small arguments with Beetlejuice about him being a real ghost demon and threatening him that you would send him back one day but you never did strangely you actually started to like him a little bit but you didn't let him know that so you wouldn't feed his ego balloon
Today, after school you were at city's place for a study session on a science quiz of course it was about biology but it never made sense to you anyway
