"You don't look..." Well, of course she didn't look over sixty. But for all her time in the Bastion, Zuko hadn't had much experience (knowingly) with people who were considerably older than they appeared. Paarthurnax was a dragon, so him being thousands of years old was easier to swallow than this. This wasn't even like Aang and his 112 years.

Wait.

"Eternally?" She was supposed to be fighting forever?
