21 – Life
They had always been backwards (her goal had been to master waterbending, then it became "save the world" and in the second action she accomplished the first; he'd only wanted to return home, but in the abandonment of that dream, gained it) and that is what pushed them onward.

22 – Jealousy

25 – Devotion
They cannot afford to waste time on each other; but they do, still, and it doesn't feel wasted.
