Control is the second episode in Season 2 of H2O: Just Add Water.


The new girl at school, Charlotte Watsford, gets splashed when Cleo tries to control the school sprinkler. Charlotte instantly develops a crush on Lewis when she sees him, knowing that they are boyfriend and girlfriend, creating a new rival for Cleo. Lewis has little success when he decides to test the girls' new and unpredictable powers; Rikki lights his plastic shark on fire, Emma explodes the fake penguin, and Cleo accidentally knocks Lewis into the moon pool. Emma helps her brother Elliot deal with a meddlesome team-mate, despite her telling the others to control their powers. Lewis' constant attention drives Cleo crazy, leading her to dump him and become only friends. The artistic Charlotte's "small and precise" brush strokes with her Japanese painting leads Lewis to help the girls in controlling their powers better.


  • This is Charlotte Watsford's first appearance.
  • The girls learn to control their advanced powers in this episode.
  • At school Cleo has a bathing suit top on under her shirt.
  • When Cleo lifted up a droplet of paint water in the ending scene, and it splashed on her canvas, it splashed in the shape of a mermaid.


  • Cleo and Lewis will get back together in "Sea Change", after Lewis saves Cleo.


  • Song Featured: "Another Now"
