Determined to cash in on Lowe's debt to her, Kate enlists the physician's help with her husband, Balfour. After a brief examination - and some testy questions from the inquisitive Balfour, who thinks Lowe seems familiar - Lowe decides what Balfour requires is not medical assistance. To Kate's surprise, he recommends unconditional love.
Meanwhile, renowned pirate Captain Sam Valentine arrives (albeit blindfolded) at the request of Blackbeard, who offers him the just-finished chronometer built by Balfour using the decrypted blueprints. The catch for Valentine is twofold: first he must sell it to William Jagger, the man obsessed with finding Blackbeard, and then he must acquire two so-called "hellburners." Once Jagger takes the chronometer back to England, Blackbeard will no longer appear alive... and thus will be free to operate with impunity. But Valentine refuses to participate in the scheme since accepting the offer would end piracy altogether. Not so good for business, in his opinion.
Despite Valentine's refusal, Blackbeard allows his old friend to remain on the island. Valentine repays his apparent kindness by recounting an embarrassing story about Blackbeard and even insulting him face to face. Blackbeard manages to leave the confrontation without bloodshed... until that night, when two of Valentine's pirates corner him at his grotto, swords drawn. With the use of a brass bell and his own fighting instincts, Blackbeard sustains only minor wounds in the quick battle, yet fails to discover who sent the assassins before they both die. While he recovers, Blackbeard eliminates Valentine from consideration due to their shared past and mutual respect. Santa Campana, however, condemns him - and Selima, ever distrustful, asks that they condemn Lowe as well.
