"Mind control?" Katara's face paled a little. "Are you serious? They can control your mind? And they're on this ship still? Why hasn't anyone thrown them off yet? Don't they think keeping it around would be dangerous? What if there are more? Who thinks it would even be a good idea that they stay on the ship?"

Katara was definitely disturbed now. The memory of fighting Hama was still in her mind, having a tendency to star in her dream every now and then. She could have really hurt Sokka and Aang when they were being controlled, and that was just their bodies. To have their minds controlled....Katara shivered. "That has to be the creepiest enemy I've ever heard of."
