Holy crap, that was the most evil cliffhanger EVER. They make you feel as low as possible with all the deaths on the good guys' side, then get your hopes up to the highest pinnacle when it looks like it's about to be epic transformation time and all the sacrifices will be avenged, then they screw over the good guys again and leave it at that.
...Damn. And the sight of Simon's blacked-out Spiral Energy meter as things took a turn for the worst was just a downer.
