Katniss felling when rue dies?

Katniss managed to control her emotions by blocking them out. Right before she died, Rue told Katniss that she had to win for her. Rue also reminded Katniss of her sister, Prim who also told Katniss that she had to win. Katniss then felt that she must complete her dead Ally's wishes and that she had to win for Prim. When Rue died, she wanted to win more than ever.
