I think it's possible Dragon may have been a former Cipher Pol agent. Otherwise, probably would've already known about his relationship to Garp. As for that power of his, I'm thinking that Electro can be taught to non-Minks similar to Fishman Karate, which Dragon mastered and took to the next level, but that has yet to be confirmed. Anyway, as much I can see a lot of possibilities for them to strike against the Government at the Reverie, I'm not sure Oda would be willing to make an arc without Luffy in it.
