Aang was listening as things happened. Because he hadn't known most of this, even after talking to a lot of the Heroes of Light and reading what he could. "So," he said. "You said you don't know what we're capable of. That's why you haven't just had Garland wipe everything out. But, I agree with Jade. Why now? If you tell us we need to find another way before the end of the year, we can do that. But only if you tell us. Right now, we can see the Calamity and guess how long we have before the crystal covers everything, but we still have months. And we're going to keep working as long as we have."

Aang could reflect on his past experience of world-saving. He wouldn't have pushed as hard as he did if Ozai's conquest wasn't on a timetable.

"And things change. Sometimes things go overlooked for thousands of years until the right person needs them at the right time. And from what everyone says, the Calamity has changed. maybe that opens new chances for us." Look at energy bending: another Avatar might have been able to kill Ozai, and Aang wouldn't have sought it out except for needing a way to stop Ozai without killing him. And Aang knew from Korra that she had her own unique problems.
