Commander Paylor has been voted in as president. Katniss learns about her trial and how Dr. Aurelius, Katniss' “head doctor,” came to her aid by stating that she is highly disturbed and shell-shocked, so they are sending Katniss back to District 12 where Haymitch will watch over her.
That said, it was stated that an emergency election took place after Katniss assassinated Coin. Commander Paylor, a vital leader in the Second Rebellion from District 8 was elected as Panem's new president.
By killing President Coin, Katniss risked her safety in order to not only avenge Prim's death but also gift the people in Panem a chance to live in a peaceful and fair country for everyone. Katniss was incarcerated for a time, and she was sent back to District 12 after she was deemed unsuitable for a trial.
Katniss searches his eyes for signs of emotion but only finds amusement in them. She remembers that they did indeed promise not to lie to each other anymore, and she realizes that Snow wasn't lying to her about Coin's role in the parachute bombing.
Snow laughs after Katniss killed Coin because he enjoys the irony of the situation. He avoided the official execution ceremony, even though Panem's citizens still take their revenge on him, while Katniss ends up snatching away the victory and power that Coin thinks she has successfully secured.
Katniss Kills Coin | The Hunger Games: Mockingjay Part 2
How did Gale kill Prim?
Before the Capitol battle, Gale had explained to Katniss his series of bombs designed to feed off human compassion: a small bomb would go off, and then when medical aid rushed in, a second bomb would go off, killing those people as well. Incidentally, it's this exact type of bomb that took Prim's life.
Did Gale mean to kill Prim? No, Gale did not mean to kill prim but he still designed the bomb. But, although he holds a small fraction of responsibility, he never meant for Prim to get hurt.
It is likely that he is a relative of Hilarius Heavensbee. In the Mockingjay - Part 2, Plutarch appears to smile as he looks at Coin's dead body, suggesting that he approved of her death.
After reading the book and watching the film, it seems clear that Lucy Gray realizes Snow was responsible for the death of his friend Sejanus Plinth (Josh Andrés Rivera). If Snow could sell his best friend down the river for personal gain, it was only a matter of time until he did the same with her.
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.
Katniss also realizes that, even though Gale had nothing directly to do with Prim's death, the bombing trap that killed her was based on one of his designs, which makes both him and Katniss feel he is somewhat responsible.
Devastated and left mentally and emotionally stranded , Johanna spent the next few years in isolation, wallowing in her sorrow and trauma. During this period of time, she served as a mentor for the tributes reaped in her 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.
Finally, Haymitch enters her room and tells her they are going home. As they head back to District 12, Plutarch describes how Snow was killed in the chaos that followed Coin's assassination. Commander Paylor has been voted in as president.
This interaction was so surprising to fans because it's not in the books at all. While, throughout the series, there's some chemistry between the two, nothing ever comes of the tension in Suzanne Collins' novels. Beyond the kiss, nothing happened between the two in the movies either.
At an unknown point in time years before the 74th Hunger Games, she was personally fired by Snow, the stated reason being due to her being too surgically enhanced.
However, when the stakes are as high as they are in The Ballad of Songbirds and Snakes, it makes sense why this character would ultimately become the series' main villain. Snow follows a path the audience can't morally follow, and when he kills Highbottom with rat poison, it solidifies his turn to evil and path toward ...
Peeta, Annie, and Beetee vote no, while Johanna and Enobaria vote yes. After some thought, Katniss demands to kill Snow. Once she receives an agreement, she votes yes, for Prim. Realizing something is up (as Katniss would never do that), Haymitch votes yes, too.
Where his movie character was calm and self-assured, his personality in the books was much more like the other clueless Capitol citizens. Regardless of which, Plutarch Heavensbee played an essential part in Panem's rebellion and contributed significantly to Katniss' survival.
Answer and Explanation: Prim is killed by a bomb at the very end of the battle. Alma Coin sees an opportunity to turn the Capitol troops against Snow, and she decides the resulting loss of life from her plan is a worthwhile price to pay.
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.
She asks Gale and his family to escape into the woods with her. He agrees happily, and confesses that he loves her. He is disappointed by her reply that she cannot love anyone romantically at such a perilous time. He is further angered when he finds out that Katniss plans to bring Peeta along into the woods.
