Prim

So there are those book characters that people think are weak when they are really not. At all. And Prim is definitely one of those characters.
(Spoilers for the Hunger Games Trilogy.)
Prim was twelve years old when the trilogy started. Her father had died and her mother had been depressed. That's pretty hard on a person. What people want is a mature character that is wise beyond their teenage years and can take care of themselves. So a person like Katniss. Prim wasn't that character when the trilogy began. Does that make her weak? She was really young. Not everyone can be a Katniss-like character.
And her sister Katniss had to be really brave when she volunteered for her at the reaping and then had to fight in the Hunger Games. There is no denying that. But on the other hand, I think Prim was really brave too. The way Katniss describes Prim walking up to the stage in the square trying to be strong, facing her fate, I think that this is when Prim starts to mature. I feel like twelve years old, it makes sense that she starts to mature about then. But then when Katniss volunteered, I think she may have even wanted to go into the arena then, if it meant her sister didn't have to. And having to watch her sister fight to the death? Katniss had some pretty scary and dangerous situations in that arena. I have an older sister, and if I had to watch her go through that stuff... it would be really, really, really hard.
Then when Katniss comes home, she doesn't find the Prim she left behind. She sees the new Prim, who helps her mom with the apothecary business and she's so sweet and caring that everyone loves her and she helps everyone she can. Tell me how that is weak. Katniss hunted for her family to be able to eat. That's really strong, she was taking care of her family. Well, Prim is taking care of people too. If she is healing them from their diseases and injuries, I think that is really strong. Katniss would agree, especially because she can't stand all the ill people that come into her home to see her mother. Not to mention how sweet and kind Prim is. Being like that to any person that you meet is amazing to me.
