There was a plan to break them out of the arena once Snow announced the Quell. The victor tributes from 3, 4, 6, 7, 8, and 11 all had knowledge of the plan, which explains why it seemed everyone was working to protect her and Peeta.
Why are they trying to save Peeta in Catching Fire?
Instead, Katniss wants to protect him and bring him home because she has strong feelings for him, even though she isn't sure what those feelings mean. Gale's hug and kind words when she returns home are a direct contrast to her newly established plan to save Peeta because of her feelings for him.
The plan is to break the victors out of the game and start the rebellion. They need Katniss because of her power and influence, but they know she won't join if Peeta dies, so they work to protect them both during the Quarter Quell.
Given that she is willing to make the ultimate sacrifice to protect Peeta, it's safe to assume that the Morphling was committed to the rebel cause. Like the other victors, she knows the power that Katniss has as a lightning rod for the rebellion, and she knows that Katniss will not help without Peeta.
Though Katniss began her journey in the Hunger Games seeing Peeta as a potential weight that would slow her down in the arena, she came to realize that he was a genuinely good person, and she didn't want to lose him. In Hunger Games: Catching Fire, Katniss grew to admire Peeta even more.
Why is Katniss conflicted about Finnick saving Peeta?
Before he rescued Peeta, Katniss saw Finnick as a threat and someone she will eventually have to kill. However, she admits she will never be able to kill him because he saved Peeta. She won't be able to look past the debt she owes him for saving Peeta's life.
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.
The following year after Lucy Gray Baird's victory, another female tribute emerged as the Hunger Games winner. Mags Flanagan became the first victor from District 4, living off of nuts and her survival skills by creating fishhooks. She was also the first victor to move to Victor's Village before serving as a mentor.
While a prisoner of the Capitol, Peeta was hijacked into believing that Katniss was not human, but in fact one of the Capitol's mutts. Conversely, Johanna Mason suggested that the Capitol's torture replaced Peeta with an "evil-mutt version" of himself.
He's letting them rescue Peeta. Because the Capitol has hijacked him: They've altered Peeta's memory and conditioned him to fear—and try to kill—Katniss. Snow knows that the thing Katniss loves most, Peeta, can destroy her, mentally and emotionally if not literally, if he never gets better.
Katniss doesn't trust him at first, mostly because Finnick is very flirtatious and seems to be working an angle. But as they work hard to survive in their second competition, Finnick becomes an ally who joins the revolution.
When he was 16, Haymitch was reaped for the Second Quarter Quell, wherein four, instead of the normal amount of two tributes from each district participated. He became an ally to a girl named Maysilee Donner, the original owner of Katniss' symbolic mockingjay pin, but was later forced to watch her die.
Finnick was willing to give up Mags to save Peeta because he needed to, to convince Katniss they were on the same side. He receives a large cut in his leg when he was trying to save Peeta. During the events of Mockingjay, Finnick shows concern for Peeta, and goes out of his way to save Peeta's life again.
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.
His feelings and memories are distorted with hallucinogenic tracker jacker venom, in a mind-control technique known as "Hijacking." The Capitol uses this method to turn Peeta against Katniss, making him believe that she is not only responsible for the death of his family, friends and the destruction of District 12, but ...
The victor tributes from 3, 4, 6, 7, 8, and 11 all had knowledge of the plan, which explains why it seemed everyone was working to protect her and Peeta.
As they discuss District 12, Peeta spirals out of control, blaming Katniss for the district's destruction and accusing her of being a mutt created by the Capitol to use against everyone. Heartbroken, Katniss tells Haymitch and Plutarch that she can't stay in District 13 anymore.
These wolf-like mutts are not just murderous creatures created to kill those remaining but horrific monsters that resemble the now-dead tributes. The wolf-like mutts act as a physical representation of how the remaining tributes have themselves become murderous monsters throughout the course of the game.
Chia Mags kisses Finnick on the mouth to briefly let him know that this is the last time she will see him. It's her way of saying "Goodbye" but in a more affectionate way.
District 12 has the most Hunger Games victors, with five winners, including Katniss, Peeta, Haymitch, and Lucy Gray. Finnick Odair is the youngest winner in history, winning at just 14 years old.
It was also insinuated that the lead heroine believed that Mags previously suffered from a stroke, which would have cleared up her limited communication. Some fans had theorized that PTSD could have been a factor when it came to Mags' lack of talking, or possibly just her old age.
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.
