35 Mortal-world years ago, Lydia started growing distant from BeetleJuice, although he hadn’t noticed until she stopped summoning him altogether. With his best (and only) friend now gone, he spent most of his time locked in his room, mostly crying face down on his bed and bedrotting- that last part isn’t exactly unusual for him, but that paired with the crying is the issue, here.

He had gone in a spiral of depression. The residents of the Neitherworld, however, were enjoying the peace and quiet of not having to worry about BeetleJuice's stunts and pranks, but they couldn’t help but be a little bit concerned about him, since during the rare occasions where he’ll come out of his house, his jokes have gotten a lot more self-deprecating.. such as “where’s a bridge when you need one?”, and “Someone should hang me for that one”. Very concerning jokes-

After several years of silence and ghosting (pun not intended), Lydia had decided to drop by the Neitherworld again, not exactly intending to see BeetleJuice again but not entirely opposed to the possibility of seeing him if it so happened to work out that way.

She was strolling through the old alternate dimension, greeting the residents and other old friends she had but wasn’t as close with as she had been with Beej, but something she soon picked up on was that whenever BeetleJuice was mentioned, either in passing or as the conversation topic, they’d get all quiet and awkward.. huh, weird, wonder what that’s about?

She kept walking through the Neitherworld, thinking about how weird everyone was acting around the topic of her old ghost-friend, until she stopped at the doors of a familiar looking wonky house.. muscle-memory must’ve lead her there after all these years.
