Sink or Swim is the 11th episode in Season 1 of H2O: Just Add Water.


Emma trains Byron for the swimming competition. At first Emma becomes the training dragon, but after Byron feels under pressure they begin get along better and even share a kiss. Byron fires Emma after she becomes harsh again, but when he wins the competition he tries to hug her and she recoils.


Byron asks Emma for training help prior to the school's swimming competition. After initially turning him down, she changes her mind but becomes a "heavy training dragon", to Byron's disappointment. Lewis continues his experiments on the girls but Rikki does not like being treated like a specimen and does her best to disrupt his research. Emma and Byron end up kissing, but Emma dumps Byron, believing that coaches should not be involved with their students. It turns out that Byron is challenging Zane; though Emma swore she wouldn't attend the race, she comes anyway and watches Byron beat Zane in the race. After the victory, Emma and Byron become friends.


  • Second time Emma and Byron kiss.
