Weston offers him a kind ear and the sailor takes him for a kind man. When Weston wakes up later in the journey he finds that the sailor has left Daisy in his care. The problem is that Daisy is a middle sized alligator. Whilst trying to throw the beast overboard, he meets Moira who helps him out. He is desperate to see her again and uses the alligator as an excuse.
