When going to war, it's good to have friends to rely on; they watch your back, and when things get dark, they give you a reason to keep on fighting. In <em>Mockingjay</em>, though, Katniss starts losing her friends one by one. Many die in battle. Those who survive the fighting have been damaged in other ways: Peeta has been "hijacked," Haymitch has sunken completely into alcoholism, Gale has been morally compromised by his involvement in the war. The loss of these important friendships really hurts Katniss, and near the end of the novel, she completely loses her will to live. The good thing is, though damaged, some friendships can be rebuilt with time.
