Um, in the story it was confirmed at the time by Mirajane and Seilah that it was only a partial Take Over. So you're both still wrong, because nobody ever predicted ever that she completely took over Seilah when the story itself said otherwise at the time. And she never kept Macro at all, because what happened was she forced Seilah to summon Elfman, hence the fatigue Seilah felt when Mirajane partially took her over; she herself never acquired Macro at any given point. She went back later and saved Seilah's life. Literally this was something that was out of the blue a surprise for everyone. >_>
