Excellent! Aang now can have an air-bro and an ice-brow. Now to hunt down people with earth or fire powers.

Aang sells candy, plus any trinkets he gets his hands on that he thinks people want. If he thinks Ian wants model planes, he can probably figure out how to get some to sell to him. And yeah, I intend him to have hair until he starts remembering more stuff and decides to start shaving his head again.
