Hmm...Iron Shadow Garjeel eh...
Natsu has used his Thunder Fire powers a couple times since he got them right? So they're permanent? I wonder if the same is going to be true of Garjeel.
I'm a little confused as to how Rogue and Sting got their powers. They supposedly have Lacrimas AND were taught slaying by dragons. But Rogue seemingly learned to be a Dragon Slayer after Garjeel left the Phantom Lords...which is well after the dragons had disappeared. So where did Rogue and Sting find these dragons they supposedly killed?
