I'll return to this once I find the time. Generally when we talk about the movie I don't have a problem with her being typed as ESI. I mean where exactly to we draw the line between a stoic and skilled ESI and a typical SLI? ESIs typically star in revenge stories, while SLIs are survivors. That however is not a rule and not strong enough for me to rule out ESI 100%. Although I don't see Katniss and Gale (agree LIE) as duals. When I type Katniss I have the books in mind which are written in first person and give a lot more information about her thought process and motivations.
Also @
hybris theory has a point. Typing fictional characters is tricky.
