Wiress

Wiress was a female tribute from District 3. She competed in and won a previous, unspecified Hunger Games, and then participated again in the 75th Games. In the second set of Games, she was at first rejected by many to be an ally, except for Katniss who wanted her as one. She later proved her worth when she revealed to her allies that the arena was shaped and operated like a clock by saying "Tick tock" repetitively until Katniss figured it out. Knowing this, Katniss and the others were able to predict the devastating obstacles the Gamemakers arranged. Wiress showed that she was always one step ahead of the others, but could only be understood by her loyal companion Beetee, and eventually Katniss. She was given the nickname "Nuts" by Johanna over the years since her victory. She died after the male tribute from District 1, Gloss, slit her throat.

75th Hunger Games
Wiress was the one who had pointed out the flaw in the invisible force fields in the Capitol. She gazed up at the field protecting the Gamemakers, and showed the square of shimmering air to Katniss, with Beetee to help her out. This fact that she gave to Katniss was essential to the victors' escape at the end of Catching Fire. Without this tidbit, Katniss would not have known to shoot her arrow into the chink of the force field, therefore destroying the dome shield surrounding the arena. She also helped Katniss figure out that the arena was designed as a clock by repeating "Tick, tock."

Alliance
Wiress allied with Johanna Mason, Blight, and Beetee on day one. The four were caught in the blood-rain in the arena, and Blight was killed by running into the force field. It is assumed that this is what made Wiress mentally unstable. She seemed unable to say much except,"Tick, tock," which later proved to be invaluable information concerning the arena's design. Johanna, Beetee, and Wiress then found Finnick, Peeta, and Katniss and allied with them. Katniss discovered what Wiress meant shortly before her death.

Death
During the 75th Hunger Games, a large spool of wire was specifically placed in the arena by Plutarch Heavensbee so Beetee could destroy the force field surrounding the arena, and consequentially Katniss's alliance could leave the arena. After Katniss figured out the arena is a clock, Wiress went to clean the wire in a stream for Beetee, and she also sang and watched out for enemies. She was attacked by Gloss, who slit her throat. After Wiress died, Katniss retrieved the wire from her corpse, which was sinking into the ocean. Beetee then took the wire and planned to use it to destroy the arena, by connecting it from the lightning tree to the force field, but it was eventually Katniss who destroyed the arena by firing an arrow wrapped in wire through a small gap in the force field, which was then electrocuted.

Personality
Wiress was described to be shy by Katniss. It was also mentioned that in the training room, she seldom completed her sentences, and Beetee had to finish them for her. Wiress was naive and kind. Blight's death in the 75th Hunger Games drove her to madness, and she could only recite comments and songs about clocks; referring to the clock shaped arena. Beetee said that Wiress was not only smart, but intuitive. She was an intellectual genius, inventive, and clever.

Appearance
In Catching Fire, Wiress and Beetee are both described as having ashen skin and black hair.
