After Prim's death, Gale leaves voluntarily because neither of them can avoid the matter of Prim's death having been caused by Gale's invention, with Katniss letting him go without a word. Katniss subsequently grows back together with Peeta, whom she finds she loves again now that he is recovered from his hijacking.
In the end, Katniss and Gale grew apart, as many childhood friends and young loves do. She needed something different in her life, and with Gale's link to Primrose's death, Katniss found a reason to cut ties. If Katniss ever wanted to find comfort again, she knew she had to return to Peeta for the long term.
Katniss didn't really have the time to consider romance when she was worried about survival. When Peeta and Gale both made their feelings clear, Katniss wasn't entirely receptive despite caring for them both. In the end, her feelings for Peeta and Gale diverged, with Peeta ultimately winning her heart.
The woods are now ruined. Katniss decides that the Capitol views her and Gale's weekly hunting trips — and the one time that Gale unexpectedly kissed her, which Snow knows about — as flaunting her defiance in front of the entire district.
Katniss's focus on survival and her family's safety prevented her from fully considering romance, but her feelings for Peeta and Gale diverged in the end. Katniss ultimately chose Peeta because he understood her trauma and she didn't want to lose him, proving her love for him.
Chaff, of course, comes right out and kisses Katniss, though his reason is more to have fun with Katniss's image than to turn it to his advantage. Finnick's and Johanna's tactics, however, are clearly deliberate attempts to manipulate Katniss, and Katniss immediately distrusts both as a result.
Gale does not marry anyone in The Hunger Games. He and Katniss talk about running away together and starting a new life in the wilderness, but they never officially marry.
Gale was responsible for creating weapons that would trigger a second wave of bombs to target first responders and combat healers. This invention potentially ended up killing Prim, but even if he wasn't directly responsible, Katniss found this tactic so abhorrent that she lost her affection for him.
Who does Gale end up with at the end of Mockingjay?
In the Mockingjay movie, Katniss confronts Gale about his role in Prim's death, which he struggles to come to terms with. Katniss, unable to look at him the same way, lets him walk away without a word and eventually ended up living with Peeta.
Although she will never know for sure, Katniss does recognize that she cannot be with Gale. She will never be able to forgive him for his idea — the parachute bombs — that killed Prim.
It's only implied that they get it on via snuggling and other affectionate acts in close quarters — but if you have read the book, they really imply that they took their relationship to the next level.
She later realizes, after a conversation with the imprisoned President Snow, that President Alma Coin sent Prim to her death (which was caused by a hovercraft by the rebels) both to sway the Capitol citizens to Coin's side by making them think Snow was bombing the children, and to swing Katniss to her side through the ...
Gale and Katniss did not see each alone until a few weeks after the end of the Hunger Games, at their meeting place in the woods. They shared an emotional reunion. At the end of a day of hunting, Gale spontaneously kissed Katniss and told her that he “had to do that, at least once.”
Katniss speculates that Coin deliberately sent Prim to die in the Capitol bombing in order to fully gain her trust, but it's never outright confirmed or denied.
Deceased. Primrose Everdeen - Blown up by President Coin's parachute bombs. Messalla - Melted in an unknown pod that trapped him before burning the flesh off him.
She was only 13 years old when she was killed in The Hunger Games: Mockingjay, and her youth only makes the tragedy that much harder for Katniss to bear after everything else she had suffered. Prim's death is a truly heartbreaking moment.
The double bomb that kills Katniss Everdeen's sister, Primrose, was designed by two rebels: Beetee and Gale, Katniss's lifelong friend. Previously, Gale had explained that the double bombs are designed to appeal to mankind's weakness for compassion.
The Hunger Games series, much like Harry Potter is for young adults, and the themes and motivations are not hard to understand. Katniss NEVER hated Peeta. She figured she'd have to kill him to survive and had no desire to like him because of that.
Gale is jealous of Peeta and the relationship he has with Katniss, and he wants Katniss to decide between them, though he doesn't press Katniss during her recovery in District 13. Gale is an excellent hunter and excels at setting snares and traps.
Essentially, Katniss was afraid that if she was to kill President Snow, then the whole revolution fails, and the rivalry would still continue. Therefore, Katniss had to sacrifice by killing Coin in order to end war, and knew that Coin couldn't do anything better than Snow to save the Panem.
While the Hunger Games film never talked about it, the Catching Fire novel explained why she could only communicate through hand gestures. Katniss briefly mentioned that a previous stroke could have caused Mags' garbled speech. However, post-traumatic stress disorder could have also caused her speech incapacity.
As the anthem blares, the victors hold hands in what Katniss says must be the first showing of public unity among the districts since before the Dark Days.
Peeta used the dyes to paint a picture of Rue after Katniss covered her with flowers when she died. He says he wants to hold them accountable for killing Rue, and Effie tells him that that kind of thinking is forbidden. Katniss then tells the team she hung a dummy of Seneca Crane.
