Only Erik Sundqvist is able to escape. Samson later catches up to Sundqvist whilst he is assisting Isla and Spike, who observe an infected woman give birth to an uninfected baby.

Samson later finds the Bone Temple and attempts to decapitate Kelson, but is prevented from doing so by Spike, who injects him with a further high dosage of morphine
