@mutsutakashi I always break Crimson plan in two: his good natured plan and his bad natured plan.
His good plan usually involves saving, like this case (he provided detailed information so the princess army can win) and usually its because of Ragna. His bad plan usually involves controlling, or taking for his own gain, and this is the one who usually failed miserably.
Its like karma, he is forced to be a good guy, and yes I laughed hard everytime it happen XD
@SakuraOrihime Crimson know about all the dragons background, so his information is reliable. The downside is, he never do this for good, he is evil in nature. So if his plan executed perfectly, they will win yes but his plan will do more harm (to the collaborator) than good.
