I feel that. Like I mentioned FO is my favorite, but I feel like the mid season finale that's about to air might be even crazier, or that one of the episodes next year could top it. But it's going to have to be a BIG episode to do that. Gus was an incredible character and seeing his demise was just epic for me. There's not enough time to introduce another character who becomes such a big player, so something crazy is going to have to happen to the main cast. I'm sure that's what's in store though. If Skylar ever dies that might end up being my favorite episode by default >.>
my favorite is probably the train robbery episode. but i havent watched the older seasons in a while so its hard to say. i really liked that scene where they kill the cartel.
