I wonder how this "Fight" will go down. Will Adam hesitate and get hit a lot til he gives up and decides he isn't upset anymore and throws away logic?! Or will he curb stomp her and run off to the tower, go through a mini-arc of destroying it solo, saving Erza, and going home as he prepares to apologize about nothing as he isn't really in the wrong for any of this?!?!?! FIND OUT NEXT TIME ON PLOT TAIL Z!!!!
Adam will probably go down as the most brutal member of Fairy Tail in history. Also, I don't think he will get his revenge against Brain. Mainly because Brain is smart and he has most probably figured out that Adam was the one slayed Deliora which means he knows that he is no match for Adam. Knowing that Adam is coming for him, Brain as a safety precaution would have already left the tower. So we will only get to see Adam destroying the Tower. I could be wrong, but I think this is the most likely outcome.
