User blog comment:Guts!/Anime Depiction of Luffy's Gear Second/@comment-5640399-20130528153249

It could be a pressure thing. The slower moving blood in the rest of the body acts like a dam to the faster moving blood in the arm. Or maybe Luffy expands the blood vessels in his arm creating a pressure gradient and causing blood to rush into the arm temporarily recreating Gear Second conditions. Point is, that is the way it's drawn, if it's in the manga and not in the anime it's a mistake on the animes part and you're all just gonna have to explain it to yourselves and move on. There are loads of these in OP, look at Brook the first time we meet him. In the Sunny's cabin he's not casting a shadow, which means that the light in the room is passing straight through him, but we can see him, which means light is being reflected from him into our eyes. Conclusion, when your shadow is stolen your body becomes a light source and manufactures the reflections of the light that goes through you and it draw the energy to make the light from the food that you don't eat in the stomach you don't have. Enel's power, is it possible to force a conductor to follow the path of the charge carriers rather than the other way around? Chopper, how do those shorts continue to fit?? Whitebeard, how do you pick up china??? Just make up some pseudo-science and roll with it, there are too many already for Oda to suddenly decide to turn round and explain them all.
