Lewis searches through a research folder on mermaids given to him by Max, somewhere in the research lies a clue to how all this happened. Charlotte becomes jealous of how much time Lewis is spending with his ex-girlfriend Cleo. When Charlotte visits Cleo, she sees a picture of Gracie on the wall and recognises her as her grandmother! Old wounds open up for Charlotte and she steals part of Max’s research: an old movie of Gracie – as a mermaid! Lewis finds himself in a race against time to stop Charlotte from watching the recording but he’s too late. How is he going to explain this?
