Brainstorming
Author-san why not while you are with Rosalie you release the climate control. You already know how to make up a little story about not knowing why while you feel sad / happy the weather changes. as it is said that the Ororo emotions of the X-men can change the weather. so you can create a cover about how Edwar got hurt, before they find out he did it
Tbh with his powers, I feel it would have been much better if instead of the whitebeard devil fruit you gave him haki. It would be so much better I feel, I make he will not only be able to anticipate any moves if he gets good enough he can see into the future, Then the armour haki for when hitting. It would make him MUCH better at when fighting, surviving etc Cause you have that for close up stuff, things that can take him by surprise won't then you still have the massive firepower and long-distance power of storm. Dunno just feels it would have suited the story much more. I mean where can he really use the df realistically? And if you talk about it can take out many at once, storms power also fits that role. It is just overall better for him with haki.
