OK, just finished reading #66 and I have to say that this particular arc has probably been the wildest ride so far. That was a great ending with Diana putting on the WW clothes and emerging as the hero we know her to be. Obviously, she and Clark are about to take on Hades' army of the dead, but I can't help but wonder if we'll see other members of the JL show up before it's all over with.
Odd observation: are we to assume that the slain JFK is part of Hades' army, given the small panel that showed the Eternal Flame in Arlington?
Final thought: If anyone shows up to help Supes and WW, I hope it's Zatanna!
