Fi disagrees, and Laron eats for for insolence.

To Laron's profound irritation, Fi disagreed with her. "I am sorry, my previous master, but I cannot accept this. This new body, as well as Ghirahim's dark magic, has addled your mind, and led you astray. Let me use the mirror on you, Master, and become yourself again."

A very, very small part of Laron, the dumb part she thought, agreed with Fi. She had been corrupted, and her ego was too large. She needed to go back to who she was. This was, of course, stupid. Corrupted? Please. She was powerful. That was what mattered. "I'm sorry you feel that way, Fi," was all Laron said before swallowing the sword spirit whole. She expected another rush of power, another tingling of change, but there wasn't. Apparently, Fi wasn't that mighty to begin with. Now then, what was she about to do again?
