"Lewis is given the chance of a lifetime with an opportunity to study overseas. But he‟s interrupted from telling Cleo by Sam and Don surprising everyone and announcing an early wedding ceremony. When Kim learns about Lewis‟ impending departure, she sees an opportunity to sabotage the event and breaks the news to Cleo. Distraught but determined, Cleo focuses her attention on organising the entire ceremony for Don and Sam on her own, outside the cafe. With Lewis as Best Man and Cleo as Maid of Honour, the ceremony is icy. Another stunt from Kim gives Lewis the opportunity to declare his love for Cleo and let her know his decision – he‟s not going. Not to be foiled by her sister, Kim plots yet another way to derail everything and this time succeeds, nearly exposing the trio as mermaids. But with Rikki, Bella, Will and Lewis‟ help, Cleo recovers the ceremony and transports it to Mako, to finally give Don and Sam the wedding they deserve. In the process, she realises she must let Lewis go to follow his dreams – and in a bittersweet goodbye, Lewis departs."
