Manchee soon finds the scent and they're back on their way. They travel up a steep hill as the sun comes up; Todd realizes that his fever isn't cured and he should have kept the rag.
They get to the top of the hill. Todd asks Manchee if Aaron planned this slow and painful death for him.
And guess what? Aaron comes out from behind a tree, affirming Todd's question with a "yes." Because of course Aaron is here.
Before Todd can react, though, Aaron is gone. Todd blinks, trying to figure out what's going on; he starts sweating and shivering.
He then sees Aaron again and hears his voice all around him, saying "killer."
Fortunately, though, this time Aaron is just the byproduct of Todd's fever—he's not actually there. Todd starts to eat.
He sees Aaron with a pre-crocodile face, reciting his sermons from Prentisstown.
Todd and Manchee continue, and Todd ignores the Aarons that he sees wherever he goes.
After walking and following the scent, Todd walks into a destroyed settlement, burnt to the ground. And Aaron is standing in the rubble. He smiles with what's left of his face as Todd threatens to kill him.
Aaron tells him that killing a Spackle doesn't count—he's still not a killer because he hasn't killed a man.
Todd's not giving in this time, though, and as Manchee barks, he raises his knife and stabs it into… wait, what? Viola?
She looks up at him confused and sad and says "Killer" (29.100).
Todd collapses to the ground and his world spins; he can't kill Aaron. He passes out.
He wakes up to Manchee licking his face, and when he stands up, he sees Aarons and Violas all over the place.
Okay, so we know that he's still hallucinating: Viola's not dead, and Aaron's not there.
Still, though, all the Violas and Aarons are calling him a coward.
Then, amid a swirl of Noise, Manchee leads Todd out of the settlement.
As they run, Todd sees (what could possibly be the real Aaron and Viola) knelt in prayer across the river.
