There are few things which we have yet to see....
1) Whirlpool - Gaban doesn't seem to have a df.
2) Black ship
3) Working for the government or associated with it
4) Shs already got one handed over to them by zou. I doubt oda would hand another one through an ally.
The first 2 just need an explanation on circumstance. A black ship doesnt really matter much to this character, but the Whirlpool could be just his strength or some technique he has too.
The WG thing was just a guess from Shiryu, it doesnt need to actually mean anything.
And Ive explained this before but Scopper giving them the RP would be contingent on Elbaf being saved from Loki or Shamrock's plan. Scopper's family is from Elbaf, so this would make sense if they were "given" it.
I mean, think about the alternatives:
- if its some unknown powerhouse then Oda has to somehow explain that history in yet another arc beyond Elbaf. Meaning we'd be even more years out from a potential climax of a 30+ year story
- If its not some strong person but a weakling, then its not really earned, it just turns into a conflict with Blackbeard or Akainu or someone else, which already would happene regardless of this happening or not.
- It doesnt have to be Scopper, but they also dont have to be evil either, meaning someone could gift the RP to the crew after this arc anyway.
When i think about the above, I would just "rather" it be Scopper because it allows all of these plotlines to come to a close and not drag it out.
Hell, maybe Shamrock finds and seizes the RP from Scopper, boom theres your "earned" aspect of getting it.
