Katniss is certainly a unique character with many special qualities and personality traits. She is brave, determined, independent, selfless, and also resourceful. She is also very clever when she puts her mind to it. Since Katniss has gone through a lot, mentally, and even physically, for example with her father's death.

It finally clicked in her head that he must have been near a water supply and eventually found him near a river bank.
