The Expanse

On one of the pods it seems Ty was hinting that there ‘could’ be a future something but nothing is in the pipeline
Pretty sure the ‘dogs’ story is a big time elevator pitch
And I think Filip’s escape was too - pretty sure he does in the book as well, but zero need to show his escape unless you hope to use him again
It's my understanding the show runner is hoping to circle back and finish the series at some point. I feel like they did a nice job of tying the main storyline up and leaving the unfinished things in a place that is less agonizing than some series finales.
