"A city?!" Well that was news to Katara! Here she thought the ship would primarily consist of all of this with the pods, but they also had a city! And these...Sensoriums? That would be a good place to practice, now that she knew they existed. HOW they existed was a very good question, but Katara was not going to start asking questions about that, leave it to Sokka, the science guy.

"That's helpful. Thank you sir! I just have one other question, if you don't mind. Are there any others on this ship that claim they can bend like me?"
