I kind of wondered if they'd all - including Michael and Janet - end up back on Earth. I don't really trust Vicky to stick to the plan either.
They've done Earth already, and it's not like Mike Shur to tread old ground. Also, Vicky's storyline really felt solid and satisfying, rather than a red herring. I'm more intrigued by the crumb trail they've laid out for the Good Place committee, which is just about the most useless batch of idiots you could imagine.
I smell a rat.
I'm suspicious of just how fatuous they are, since the narrative about the Bad Place has always been more nuanced. Maybe Bad Demons are just inherently more interesting and fun, but just how Good can the Good Place be when it's run by sycophantic imbeciles? Maybe team Cockroach's next challenge will be completely remaking the Good Place into somewhere you'd really like to spend eternity, because so far I haven't seen the appeal.
