I expect the RA to make some moves, although not sure how Dragon is supposed to cover all that distance and reach Egghead in a day.
Wind logia, He can travel as fast as a cyclone\typhoon\storm does. I know the distance is far but why wouldn't Dragon interfere with the execution of Vegapank since we know he is very close to him(when he talked to Shaka, he interrupted when Shaka said he will die soon)?
Garcia being guarded by one admiral and few ships is another chance for Dragon to make a statement. Catching a Elder will surely pave way for his goal, wouldn't it?
