After being persuaded to betray Riku and join the Crabs, Selphie and the rest of Tidus's team arrive at Riku's hiding place, the broken bridge. Sora and Riku easily knock the other four children into the water, making the Crabs lose the game of Island War.
After Island War, Selphie sits daydreaming on the beach.
Selphie fights alongside Tidus and Wakka in a play battle against Riku, but all three are defeated easily.
Selphie reveals to Riku that she knows about his and Sora's relationship. She tells him that she considers them to be meant for each other, which impresses Riku, as she is "the Queen of Romantics".
