“[…]You need someone different from me.”
“No, Haymitch, we need someone exactly like you.” 
“Just luckier?” I say. 
“Luckier, or with better timing.”

Haymitch and Plutarch hold the above conversation in Chapter 27 after Plutarch pulls Haymitch aside during his Victory Tour and asks him to join the rebellion. Here, Haymitch says the movement is going to need a different type of leader because he failed. Plutarch tries to reassure him, claiming he was exactly what the movement needed and that just because they failed today does not mean that they will fail tomorrow—a nod to the outcome of the war in Mockingjay, in which they do ultimately topple the Capitol. Plutarch’s remark that they need someone “exactly like” Haymitch anticipates the moment in the Epilogue when an older Haymitch agrees with Peeta that he and Katniss are a lot alike. The link between Katniss and Haymitch is essential to the reader's understanding of both characters. The Girl on Fire and the boy with the flint-striker are two sides of the same coin, and it’s clear the rebellion would not have succeeded without the two of them.
