Prompt 1: Defiant

I'm currently doing a 30-prompt challenge (table C here); I'm trying to do one a day, and I'm doing pretty well, though I mostly start them on the official day and finish them later. I'm up to about seven or so, and am really enjoying it.

Prompt One is "Defiant", which succinctly describes the initial dynamic between Katara and Pakku; both of them are stubborn as mules!
