16 – Weakness
It's horrible to watch a Waterbender dehydrate, to see their spirit curl up and flicker out (he's mixing it up again; a Waterbender, at times, will shimmer; and that's a close as their appearances get to flickering) as well as their body; this is why, and for no other reason, he gives her what is left of his own disappearing rations.

17 – Tears
Out of sheer hysteria she tries to scream (make them stop), but Zuko covers her mouth and bruises her arm in his grip to keep her out of sight and she dampens his hand while he saves her life in place of Aang's (stop).

18 – Speed
"If I beat you, will you stop chasing him?" He shifts; replies, "If I beat you, will you let me have him?"

19 – Wind
She hears someone calling her, pleading with her ("No, not him; don't go with him.") and she risks one glance behind her before grasping his hand to step onto the ship; oh, it was just the wind.

20 – Freedom
She turned; he bared his teeth in a bastardization of a grin as if to say, "You thought you were rid of me? It's not that easy, girl."
