Finally, some epic Makarov. While the explanation for Fairy Law comes a bit late, it makes some sense. But, it makes too much sense, in that it actually creates some further questions, like:

If the cost is so high, why did you use it against Phantom Lord, then? The only possible answer I see is that the shadow soldiers or whatever don't count, the elemental four was already out, thus Jose Porla counted as only "one" enemy, so the cost was mitigated to be negligible. But then, he could've easily finish him with the giant form alone, so why use something so risky at all? The situation against PL hardly warranted a last ditch effort like that, after Makarov was on his feet.

Yet it doesn't make enough sense since it still doesn't answer some questions, like:

The situation against Tartaros, however, still did, even factoring in the cost. I wonder if Makarov's thought processes went somehow like this: "Okay, let's see. Most of my guys are in grave danger fighting against enemies who should logically be out of their leagues, Magnolia is getting destroyed, and all the Faces will active in like a few minutes. Fairy Law, then...? Nah, let's wait for Nakamagic instead, and let the blind and crippled Erza sort out this Face thing. She'll be fine." -- yep. Good call, old soldier. Good call. >_<

My vote is on that the "cost" is not there to give us explanation about anything, but as an easy plot device for creating some sense of drama.

Oh well. Still better chapter than the last one. And still a better love story than Twillight.
