I actually think that glare from Erza is a power that had been for shadowed all this time from all the times she scared the heck out of the Natsu and the others. Or it is just Haki. XP

Either way, that looked cool how she was defeated, good to know that there is a limit as to how much she can fight.

I am really looking forward to Eileen's introduction!

Besides Carrot, even though I wouldn't mind seeing a character suffer more as the next person, but in chapter 416, it is declared that during those weeks after the Tartaros arc, she was going through some Post Traumatic Stress, it was thanks to Jellal's words of encouragement that helped end it. I doubt with a strong will like hers she would fall for the same experience twice.
