Finnick was lagging behind Katniss and Peeta, so he wandered the arena by himself, trident at the ready Suddenly, he was attacked by monkeys, but he deftly fought them off, trying to get as far away as possible He retreated to the beach, but two monkeys swooped down on him, and while he was fighting off one, the other was preparing to deliver a fatal bite, when suddenly it was struck by a bow arrow and killed. He killed another monkey and returned joyfully

"Thank you, Katniss... I thought you-" Finnick says, breathing heavily, but he saw you...not Katniss...He saw you draw an arrow on the bowstring and give him an almost deathly serious look.
