World-building: We come to see in this chapter that the Games aren't just a punishment for the districts, they're also entertainment for the Capitol. The Capitol hated the year when there was no wood so the tributes mostly froze to death, because of all the bloodless deaths that didn't stir any excitement. Then also Katniss starts to talk strategies, about her own refusal to cry and her thoughts leaping to why Peeta is crying, if it is to make himself look like he isn't a threat. We also hear about the children who train to enter these games and their fierceness. This puts the Games in a whole new perspective, that it isn't just to be thrown in and go, it's thought out. Katniss will have a lot more challenges than we thought, and this also reflects back on the society that not only made these Games, but made them competition and entertainment like the Olympics are today.
- Katniss: In this chapter we get the first sign of Katniss having any type of rebellious streak in her. It's small, but when she eats her food with her fingers to annoy Effie, it gives us a sense of what type of behavior Katniss may have later. And despite her doubt that she can win, we see Katniss using strategy, trying to figure out others' strategies, and determining how she can best survive. We've observed her survival skills in the woods, and now we're really seeing her mind at work.
- Effie: She's our only Capitol character at the moment, and she's characterized as an epitome of what the Capitol is. She worries about her appearance when they watch the footage of the reaping again, and when they eat dinner she talks about how last year's tributes, two starving children, had eaten so sloppily it upset her digestion. Yes, when she was taking them to their death.
- Rue: Well, we don't know her name is Rue yet. But we're connected with her as the girl from District 11, who reminds Katniss of Prim. We don't even know her yet, but we sympathize for her because unlike Prim, no one steps up for her. She is who Prim could have been.
What we can learn in a nutshell: Foreshadow your character's traits that will be important later on. Make sure that readers can find a seed in them what they're meant to do in the future. Also, be sure that your character fits the story you've put them into. Don't forget when world-building to also set up the society's morals, feelings, manners, etc. into perspective for the reader. And of course, with the tension, throw more boulders at your characters. Make them rely on something or someone that will hold them down.
