True, but I've seen shows that have their production number in different order (like the Boondocks where their 101 wasn't the first episode to air). It's the production of when it was made, not when it will air.

Also, they're not going to give away their big plot point in the trailers. We didn't see Twi being corrupted in the mirror in the trailers for the season 3 premier, after all.
