Not just Aang. [But that gets a smile out of her.] They were a group. Katara, Sokka, Toph, Zuko and Suki. Aang couldn't have stopped Firelord Ozai and ended the war without them.

[after a moment, it occurs to her] Ozai was Sozin's grandson. Sozin, Azulon, and Ozai were the three firelords during the war.

[She feels a little bit like she's reciting her history lessons. Wouldn't her masters be proud!

.........considering she's naked and come-encrusted, no, probably not. But they'd probably be surprised she remembered Azulon. He was pretty much the firelord that history forgot; his atrocities were overshadowed by both his father and his son.]
