(Rewind to the Tracker-Jacker scene) Rue's POV
Rue felt guilty. She made a mistake. She disobeyed Peeta and told Katniss to cut the branch down, resulting minor injuries for Peeta & Katniss. Her planning killed Glimmer. Rue never felt worse in her life. She followed Katniss through the woods, and when Katniss fell in the puddle, she ran to Katniss' aid, she dragged Katniss under a big tree and put some medicinal herbs on her stings after removing the stingers. She hoped Katniss would wake up soon.
Marvel's POV
Marvel was very jealous of Cato, he was in love with Glimmer. But Glimmer never saw it. When Glimmer died. Marvel broke down and snipped a lock of her golden hair. He thought to himself that he would hold it when he was about to die, which he knew was very soon. He followed Clove to Cato, he was ready to kill Clove but when Clove turned around she said "I'm really sorry Marvel. I know you had feelings for her. And I have feelings for Cato. So I understand how you feel." They continued walking.
