Prim. I think one of the biggest things that drew me to The Hunger Games was that Katniss was willing to sacrifice herself to protect her sister. When I saw the movie, at the part where Katniss volunteers as a tribute, I literally leaned over to my boyfriend and said "If they chose my sister, I would volunteer in her place too." Prim felt like she could have been my sister. I liked Rue, but maybe I didn't get attached to her because I knew she would die from the moment she was introduced compared to when Prim died in the third book... it was such a shock. I really thought she was going to live.
