Terra's axe lands a second after Camilla's. He doesn't know quite where he is or how he got this weapon, but combat is what he's trained for. And there doesn't seem to be any question of who's on the right side, not when he's just watched this "Ifrit" seem to control the minds of others. He still remembers when Maleficent...
