THE DISTRACTION, KAIRIThe following information is the way Saix interacts with Kairi in the video game version of Kingdom Hearts II. Different games give off different information with this relationship. To view Saix's relationship with Kairi in other games, try each individual section in the main navigation above.
Kairi is the ultimate weapon against Sora, and knowing that, Saix is determined to find her and capture her in order to manipulate Sora into cooperating well with the Organization. After Kairi runs away from Axel's capture, she winds up in the hands of Saix and the rest of the Organization. Kairi gets put behind bars in order to keep her secured in the hands of the Organization. In one scene Saix is shown talking to Kairi while she is behind bars, where he tells her he will "take [her] to see Sora," with an evil grin on his face. Understanding that it probably would be a trap, she refuses to go see him. Kairi escapes the bars because of Namine and they start running away. Saix stops them and they hold up their fists to fight. Saix starts saying if he had a heart he'd be dying laughing at the sight of them. Riku comes and saves them, so Saix flees into a portal and gets away.
