Invidia
It's incredible, he thinks, that Effie can be so ridiculously clueless about the world she lives in. She believes so ardently in righteousness of the Government. Absolutely nothing he can throw at her phases her in the slightest.
He believed in things once upon a time. He remembers when he was a small boy knowing that his father would keep him safe from all the monsters in the darkness. Then the mines claimed his father and the Hunger Games killed his family and his girl. Alcohol drowned out everything else good in his world.
Jealousy flares and twists low in his belly; he wishes he was Effie Trinket. He wants more than anything to have something he can put his trust in. He wants to believe.
