I think season 3 is shaping up to be all AWESOME! The fact that both of the songs are from the same episode definitely changes things up, I wasn't expecting that. The thing I'm looking forward to the most is the Celestia/Luna conflict... I mean, the clash of two god-like ponies is most likely going to be epic! And as Thoth said, this may be where Discord comes in... Definitely looking forward to that as well. And on a tangent off of the Celestia/Luna conflict, I've been thinking about Halloween/Nightmare Night a bit. And I've come to the conclusion that Nightmare Night must be the night that Luna "snapped" and tried to plunge Equestria into eternal night. It makes sense, since Nightmare Moon would only have been around that night only, thus spawning the legend.
