She reveals her ability to wield the Keyblade to him and looks after him when he falls into a coma for several weeks in conjunction with Sora being put to sleep to regain his memories.
When Xion runs with her Keyblade, she grasps it with two hands instead of slinging it over her shoulder as Roxas does.
While Roxas cradles her in his arms, she tells him that she chose to sacrifice herself to slow down Xemnas's plans, asks that he prevent Xemnas from obtaining Kingdom Hearts, and tells him that she is glad that she met him and Axel.
When Roxas wakes up from his coma, Xion is happy and gives him a shell to listen to on the clock tower.
