I dont think Hook traded to Blackbeard. If he did, he would know Blackbeard wasn’t dead in SB and assuming Ariel saved him, that Ariel got her happy ending. If Hook knew about Blackbeard being alive, I think we’d have to accept a retcon on the eipisode where we see that whole Ariel/Hook/Blackbeard thing.
