Yeah I agree, it seemed like he didnt get them from him, he destroyed Laws sub before he could take them, he could have warped onboard with Auger and taken them by force.
Unless Auger warped onboard afterwards before the sub sank entirely and got them? But Im presuming Law has them on his person or Bepo does and when they escaped, they took them with themselves?
Hopefully Oda will confirm whether Law still has them or Blackbeard does soon but he might let BB get Laws to parallel Shanks getting Kidds ones and thus equalling it out that way.
