CHARACTERS HISTORY (taken from Wikipedia):

Johanna Mason:
Sarcastic and mean-spirited, Johanna's first meeting with Katniss involves her stripping out of her tree costume in order to make Katniss uncomfortable. She reveals that she has no friends or family in District 7, stating "there is no one left I care about." She won her original Hunger Games by pretending she was a weakling so no one regarded her as a threat, but Katniss describes her as being a "vicious killer." Johanna teams up with Katniss, Peeta, and Finnick in the Quarter Quell, bringing Beetee and Wiress with her, because that was the only way to ally with Katniss. Katniss describes her presence as being akin to having an older sister who hates you. Johanna is captured by the Capitol at the end of Catching Fire. In the third book, she is rescued along with Peeta and Annie and brought to District 13, where she fights with rebel forces and improves her friendship with Katniss. She is to fight in the Capitol with Katniss (although not as a sharpshooter—being from an area where lumber is the main export, her main weapon is the axe) but during training in District 13 she panics when the training arena is deliberately flooded. Katniss later learns Johanna has a fear of water, which developed from her Capitol torture: being soaked in water and given electric shocks. Because she and Katniss refuse to be held in the District 13 hospital due to their supposed mental illnesses, they convince the officials of District 13 to let them room together. Johanna is part of the committee that votes whether or not to hold one last Hunger Games, and she votes yes.

Bonnie:
Katniss meets Twill and Bonnie in the woods during Catching Fire. Both are from District 8 and are rebels. Twill proves this by holding out a piece of bread with the image of a mockingjay; it is the first time where Katniss sees that the mockingjay has become a symbol of rebellion. Bonnie and Twill are on their way to District 13 and they are the first to tell Katniss that District 13 may exist. However, in Mockingjay, it is mentioned that the pair never made it to 13, and they are presumed dead. Katniss also begins to ponder the reality of district thirteen, when the show the same footage of the burned-down justice building.

Love Johanna :)

Obviously.

Easy competition.
