sipping on primordial soup

In this AU, the twins have been slotted into the premise/plot of GGG as a pair of additional gods.

Ingo and Emmet are the twin gods of transportation: arrival and departure, the destination and the origin, etc. They run a shared two-way train through the towns of the Grove, from BuzzHuzz to the Grove Cove.

Their god room entrances are in the two engine cars located at the opposite sides of the train, yet they share a god space from ascending together.

Additionally, their engine cars can only move forwards; Ingo can only move towards the Spire while Emmet can only move towards the docks. They rely on one another to pull the train back and forth in tandem.

One day, a letter arrives from King that suggests though they've always move together, haven't they always wondered who's the better god between them? Who can pull the most weight, who can run the fastest, who is the most popular between the two? Clearly one of them has to be the best god of transportation.

Ingo and Emmet, who love competition and challenges, had already exhausted most physical comparisons (with most ending in a tie). Popularity is new territory though. Sounds fun, so why not?

Ingo and Emmet host a contest poll for who's everyone's favorite god between them (only between them, because they'd be grossly outpaced by other gods like Inspekta), which is kind of Splatoon Splatfest-like in festivity. The mood starts off great, and the Bizzyboys are a great help with decorating and hyping up the contest.

Maybe a little too good. Over the course of the event, some people start getting a little too hyper and competitive. The poll is now no longer fun for the weird groupies/chronically online sub groups, and they're quickly ruining everyone else's experience. Eventually it gets wayyy too serious. The twins fail to notice how bad it's getting.

Eventually Ingo is announced the winner. Both twins are happy with the results; it's Emmet's groupies who aren't. Harassment between groupies escalates to the point that one day, while the train is waiting to depart from BuzzHuzz's station, someone goes and decouples Ingo's engine car from the train cars.

When it's time to depart to the Grove Cove, the train, unknowingly, leaves him behind.

Now Ingo and Emmet are separated on the two furthest ends of their tracks, unable to reverse and reconnect their cars. They remain that way for what seems like an eternity...
