Don't think you were asking me, but:

We now can be pretty certain that Drake has haki, it's possible that that was swamp dripping from his jaws, but it's reasonable to assume it's blood. Nothing else massively new was revealed, though, we already knew that there was a link between Scotch, Drake and Kaido, now the only question is whether Drake is a subordinate of Kaido or Scotch now works for Drake, and someone else has already mentioned this...

Something to think about. Brownbeard mentions five pirates as being the most active, saying that anytime something tragic or dangerous happens, it's one of them. Blackbeard, Hawkins, Law, Kidd and Drake. Now, Blackbeard is a Yonko, likely with a huge fleet, but only he gets accredited by Brownbeard when his crew does something. Kidd, Law and Hawkins we know have nothing to do with any Yonko, so they get credit for their own shenanigans. And so does Drake. If it's Drake whose causing trouble instead of Kaido, then it's possible that this is evidence that he never joined him like we all assumed. Just a thought...
