Their swords clash, and she is laughing. Not because it's funny, but because she has been waiting for so long, and now he's finally here, and she's finally won. She smiles, because she knows he doesn't really stand a chance, and even if he does win, they will all die anyways, as her creation was threaded into the very existence of Hyrule. In the end he's an easier fight than her brother, and she can't understand how he was made to fight him to save her, and now she's slain both of them. She guesses it doesn't matter all that much, as now they are dead, and she was made to be forever, and they were made to be temporary, until Farore and Din learned to make them like her. She leaves the sword in his heart, and waits.
