The bitch will go down, and erza will do it. I mean fairy tail+strong emotions=mayhem. And erza packs a lot of mayhem. when that fight is over I expect to see filet de tigerbitch, and if erza can't, let sting loose on her, that could be satisfactory...
I was rather hoping that a Erza who lose her head walks straight into whatever trap Minerva has set up for her, leaving a SB victory.
