Demyx waited in the Keyblade Graveyard, alone with his thoughts as the war between light and darkness raged. He was due to pick up another replica, by order of Vexen, but he wasn't allowed to be seen by the Organization. He'd felt so many emotions in the past day, all beginning with his encounter with Larxene. She loved him. She proved it! And it made him the happiest guy in the world with their impossible moment. He put a finger to his lips, trying to preserve the memory of her kiss forever.
Choosing between his two favorite activities, music and napping, he began to play his sitar, alone in the Keyblade Graveyard. For a moment, his song was joyful at his musings on Larxene's mutual feelings. The wind changed, and his song suddenly became somber. She would have to fight the seven lights and fade away to recompletion or become a vessel for Xehanort's heart. Either way, he may never see her again, losing her forever. He continued to play, closing his eyes to listen to his own music. Man, he must really be the wrong guy for a happy ending.
