By the end of this, I'm betting we probably get to see everybody at least two more times, right? The pirates...Black Leather Bounty-hunter Chick...the glider-wheelchair guy...the Mad King...Auntie Wu...

Without spoilers, I will merely agree that no show worth its flying bison should introduce an awesome cast of characters just to discard them completely in future. And a viewer should keep in mind that given the amount of awesome put onscreen in the first season, there may be more to come in future.
