Crusoe and Friday are startled after a rescue ship arrives off the coast of the island. Upon reaching the beach, they find a shipwrecked lifeboat, and save the sole survivor from being drowned by the current, whom they later discover to be Jeremiah Blackthorn. Crusoe is overcome with joy and gratitude, but Friday isn't convinced that Blackthorn's intentions are pure. Reading Friday's claims as a misunderstanding, Crusoe encourages Friday to spend time with Blackthorn and get to know him. Back in England, Olivia rescues Susannah from the mental institution Blackthorn placed her in, and they set out to discover Blackthorn's true intentions.
