Step-by-step explanation:
In Suzanne Collins' novel "Mockingjay," the final book in "The Hunger Games" trilogy, there is a period when Katniss Everdeen doesn't see Peeta Mellark with the others due to a specific situation.
During the rebellion against the Capitol, Katniss becomes the symbol of the rebellion, known as the Mockingjay. She is used as a propaganda tool and sent on missions to inspire and rally the districts against the oppressive regime.
At one point, while Katniss is away on a mission, Peeta is captured by the Capitol and held as a prisoner. He undergoes intense physical and psychological torture, including hijacking, a process that manipulates his memories and emotions, turning him into a weapon against Katniss and the rebellion.
Due to Peeta's captivity and the manipulation he undergoes, he becomes a danger to Katniss and the others. The rebels keep him isolated and separate from Katniss to prevent him from causing harm or triggering his hijacked state.
Katniss is initially unaware of Peeta's condition and the extent of the Capitol's manipulation. When she eventually learns about his captivity and the danger he poses, she becomes determined to rescue him and help him recover from the trauma he endured.
Therefore, the reason Katniss doesn't see Peeta with the others is because he is being held captive by the Capitol and kept separate to ensure the safety of everyone involved.
