Firefly Musings: If the show *had* continued, what would've happened?

As all Firefly fans know, the show was canceled after twelve episodes (fourteen if you count the two that never aired.) Serenity came out in 2005, but although it answered some questions, it wasn't quite a finale.

So here's something I've been wondering for a while now: what would Firefly have looked like had it gone on beyond one season? Beyond two?

Under the cut are some of my thoughts. I'd definitely like to know yours too. Please note that the cut includes a significant spoiler - it's something very shocking that I've heard around the internet pertaining to a certain character.
