I really do not like making statements like this because they may or may not sound stupid, but I wonder if this can really happen.
We all know Dragon is wanted by the government for being a revolutionary and stuff. And we also havent seen Dragon for a LONG TIME, we havent even heard of him ever since Lougetown. We also know that the SH are in a bit of a dilemma with the Buster Call and stuff, and they are at their limit. I dont think they can handle fighting 5 VA's. Personally, I dont think the VA's will back down and run away. It just doesn't seem like something the VA's would do. They are strong as Ao Kiji and unless some miracle happens I dont think they would wussy out and run away. Thus where Dragon comes in, he is against the WG, what better way to stand up to them by helping the SH defeat the Buster Call? I think its about time Oda give us a little bit more of a hint as to who Dragon is exactly.
I am probably not the only person who has thought of this. This may be a stupid idea, but it seems likely, no?
