DEAR GOD, this arc makes the finale essentially a 6-parter going back to "Tears of a Sea Cow". This series is PHENOMENAL.
Favorite moment: There are so so so so so many, but I have to go with the Brock shark. Having done theatrical ministry before, I was dying at the Ephesians armor, the power of prayer, and the only weapon you'll ever need.
How can they top this week's episode? MORE BROCK SHARK! Seriously though, I expect the Triad and JJ involoved somehow.

Yeah, nothing really tops the Brock shark. However, I'd like to give honorable mention to "Helper often speaks of the coming war between man and the brotherhood of machines" and "What is it with you sword guys? You're always talking about how cool your swords are." I'm still not sure how the ORB is supposed to play into the season finale, though. Maybe that's just something for next season, I guess.
Actually, the best part of the episode is the segment on Adult Swim. Totally awesometastic stuff in the two minute video. Holy Diver was pretty awesome, and I didn't expect the Bibleman and Centurion references. And poor Gary Busey...
I don't watch the show, but one thought occurred to me as I read your theory: it's possible that they record a lot more than they show, and so it's in the editing that they tip off that it's a big moment or whatever.
