I thought we were into taking down a Yonkou, (unless DonFla is now one,) not a SB
Dfla is not an Emperor and the plan still stands. What changed was the involvement of Vergo and by extension Dfla which blindsided Law big time. If catching CC was a means to get to Joker/Dfla then I really have no idea how it would work.
I love this arc lol, so unpredictable.
